Purpose: ! ------- ! User subroutine. ! Fill boundary conditions arrays (icodcl, rcodcl) for unknown variables. ! Introduction ! ============ ! Here one defines boundary conditions on a per-face basis. ! Boundary faces may be selected using the 'getfbr' subroutine. ! getfbr(string, nelts, eltlst): ! - string is a user-supplied character string containing selection criteria; ! - nelts is set by the subroutine. It is an integer value corresponding to ! the number of boundary faces verifying the selection criteria; ! - lstelt is set by the subroutine. It is an integer array of size nelts ! containing the list of boundary faces verifying the selection criteria. ! string may contain: ! - references to colors (ex.: 1, 8, 26, ...) ! - references to groups (ex.: inlet, group1, ...) ! - geometric criteria (ex. x < 0.1, y >= 0.25, ...) ! These criteria may be combined using logical operators ('and', 'or') and ! parentheses. ! Example: '1 and (group2 or group3) and y < 1' will select boundary faces ! of color 1, belonging to groups 'group2' or 'group3' and with face center ! coordinate y less than 1. ! Operators priority, from highest to lowest: ! '( )' > 'not' > 'and' > 'or' > 'xor' ! Similarly, interior faces and cells can be identified using the 'getfac' ! and 'getcel' subroutines (respectively). Their syntax are identical to ! 'getfbr' syntax. ! For a more thorough description of the criteria syntax, see the user guide. ! Boundary condition types ! ======================== ! Boundary conditions may be assigned in two ways. ! For "standard" boundary conditions: ! ----------------------------------- ! (inlet, free outlet, wall, symmetry), one defines a code in the 'itypfb' ! array (of dimensions number of boundary faces). ! This code will then be used by a non-user subroutine to assign the ! following conditions. ! Thus: ! Code | Boundary type ! -------------------------- ! ientre | Inlet ! isolib | Free outlet ! isymet | Symmetry ! iparoi | Wall (smooth) ! iparug | Rough wall ! These integers are defined elsewhere (in paramx.f90 module). ! Their value is greater than or equal to 1 and less than or equal to ! ntypmx (value fixed in paramx.h) ! In addition, some values must be defined: ! - Inlet (more precisely, inlet/outlet with prescribed flow, as the flow ! may be prescribed as an outflow): ! -> Dirichlet conditions on variables other than pressure are mandatory ! if the flow is incoming, optional if the flow is outgoing (the code ! assigns zero flux if no Dirichlet is specified); thus, ! at face 'ifac', for the variable 'ivar': rcodcl(ifac, ivar, 1) ! - Smooth wall: (= impermeable solid, with smooth friction) ! -> Velocity value for sliding wall if applicable ! at face ifac, rcodcl(ifac, iu, 1) ! rcodcl(ifac, iv, 1) ! rcodcl(ifac, iw, 1) ! -> Specific code and prescribed temperature value at wall if applicable: ! at face ifac, icodcl(ifac, ivar) = 5 ! rcodcl(ifac, ivar, 1) = prescribed temperature ! -> Specific code and prescribed flux value at wall if applicable: ! at face ifac, icodcl(ifac, ivar) = 3 ! rcodcl(ifac, ivar, 3) = prescribed flux ! Note that the default condition for scalars (other than k and epsilon) ! is homogeneous Neumann. ! - Rough wall: (= impermeable solid, with rough friction) ! -> Velocity value for sliding wall if applicable ! at face ifac, rcodcl(ifac, iu, 1) ! rcodcl(ifac, iv, 1) ! rcodcl(ifac, iw, 1) ! -> Value of the dynamic roughness height to specify in ! rcodcl(ifac, iu, 3) ! -> Value of the scalar roughness height (if required) to specify in ! rcodcl(ifac, iv, 3) (values for iw are not used) ! -> Specific code and prescribed temperature value at wall if applicable: ! at face ifac, icodcl(ifac, ivar) = 6 ! rcodcl(ifac, ivar, 1) = prescribed temperature ! -> Specific code and prescribed flux value at rough wall, if applicable: ! at face ifac, icodcl(ifac, ivar) = 3 ! rcodcl(ifac, ivar, 3) = prescribed flux ! Note that the default condition for scalars (other than k and epsilon) ! is homogeneous Neumann. ! - Symmetry (= slip wall): ! -> Nothing to specify ! - Free outlet (more precisely free inlet/outlet with prescribed pressure) ! -> Nothing to prescribe for pressure and velocity. For scalars and ! turbulent values, a Dirichlet value may optionally be specified. ! The behavior is as follows: ! * pressure is always handled as a Dirichlet condition ! * if the mass flow is inflowing: ! one retains the velocity at infinity ! Dirichlet condition for scalars and turbulent values ! (or zero flux if the user has not specified a ! Dirichlet value) ! if the mass flow is outflowing: ! one prescribes zero flux on the velocity, the scalars, ! and turbulent values ! Note that the pressure will be reset to p0 on the first free outlet ! face found ! For "non-standard" conditions: ! ------------------------------ ! Other than (inlet, free outlet, wall, symmetry), one defines ! - on one hand, for each face: ! -> an admissible 'itypfb' value (i.e. greater than or equal to 1 and ! less than or equal to ntypmx; see its value in paramx.h). ! The values predefined in paramx.h: ! 'ientre', 'isolib', 'isymet', 'iparoi', 'iparug' are in this range, ! and it is preferable not to assign one of these integers to 'itypfb' ! randomly or in an inconsiderate manner. To avoid this, one may use ! 'iindef' if one wish to avoid checking values in paramx.h. 'iindef' ! is an admissible value to which no predefined boundary condition ! is attached. ! Note that the 'itypfb' array is reinitialized at each time step to ! the non-admissible value of 0. If one forgets to modify 'typfb' for ! a given face, the code will stop. ! - and on the other hand, for each face and each variable: ! -> a code icodcl(ifac, ivar) ! -> three real values rcodcl(ifac, ivar, 1) ! rcodcl(ifac, ivar, 2) ! rcodcl(ifac, ivar, 3) ! The value of 'icodcl' is taken from the following: ! 1: Dirichlet (usable for any variable) ! 3: Neumann (usable for any variable) ! 4: Symmetry (usable only for the velocity and components of ! the Rij tensor) ! 5: Smooth wall (usable for any variable except for pressure) ! 6: Rough wall (usable for any variable except for pressure) ! 9: Free outlet (usable only for velocity) ! The values of the 3 'rcodcl' components are: ! rcodcl(ifac, ivar, 1): ! Dirichlet for the variable if icodcl(ifac, ivar) = 1 ! Wall value (sliding velocity, temp) if icodcl(ifac, ivar) = 5 ! The dimension of rcodcl(ifac, ivar, 1) is that of the ! resolved variable: ex U (velocity in m/s), ! T (temperature in degrees) ! H (enthalpy in J/kg) ! F (passive scalar in -) ! rcodcl(ifac, ivar, 2): ! "exterior" exchange coefficient (between the prescribed value ! and the value at the domain boundary) ! rinfin = infinite by default ! For velocities U, in kg/(m2 s): ! rcodcl(ifac, ivar, 2) = (viscl+visct) / d ! For the pressure P, in s/m: ! rcodcl(ifac, ivar, 2) = dt / d ! For temperatures T, in Watt/(m2 degres): ! rcodcl(ifac, ivar, 2) = Cp*(viscls+visct/sigmas) / d ! For enthalpies H, in kg /(m2 s): ! rcodcl(ifac, ivar, 2) = (viscls+visct/sigmas) / d ! For other scalars F in: ! rcodcl(ifac, ivar, 2) = (viscls+visct/sigmas) / d ! (d has the dimension of a distance in m) ! ! rcodcl(ifac, ivar, 3) if icodcl(ifac, ivar) <> 6: ! Flux density (< 0 if gain, n outwards-facing normal) ! if icodcl(ifac, ivar)= 3 ! For velocities U, in kg/(m s2) = J: ! rcodcl(ifac, ivar, 3) = -(viscl+visct) * (grad U).n ! For pressure P, in kg/(m2 s): ! rcodcl(ifac, ivar, 3) = -dt * (grad P).n ! For temperatures T, in Watt/m2: ! rcodcl(ifac, ivar, 3) = -Cp*(viscls+visct/sigmas) * (grad T).n ! For enthalpies H, in Watt/m2: ! rcodcl(ifac, ivar, 3) = -(viscls+visct/sigmas) * (grad H).n ! For other scalars F in: ! rcodcl(ifac, ivar, 3) = -(viscls+visct/sigmas) * (grad F).n ! rcodcl(ifac, ivar, 3) if icodcl(ifac, ivar) = 6: ! Roughness for the rough wall law ! For velocities U, dynamic roughness ! rcodcl(ifac, iu, 3) = roughd ! For other scalars, thermal roughness ! rcodcl(ifac, iv, 3) = rought ! Note that if the user assigns a value to itypfb equal to ientre, isolib, ! isymet, iparoi, or iparug and does not modify icodcl (zero value by ! default), itypfb will define the boundary condition type. ! To the contrary, if the user prescribes icodcl(ifac, ivar) (nonzero), ! the values assigned to rcodcl will be used for the considered face ! and variable (if rcodcl values are not set, the default values will ! be used for the face and variable, so: ! rcodcl(ifac, ivar, 1) = 0.d0 ! rcodcl(ifac, ivar, 2) = rinfin ! rcodcl(ifac, ivar, 3) = 0.d0) ! Especially, one may have for example: ! -> set itypfb(ifac) = iparoi which prescribes default wall ! conditions for all variables at face ifac, ! -> and define IN ADDITION for variable ivar on this face specific ! conditions by specifying icodcl(ifac, ivar) and the 3 rcodcl values. ! The user may also assign to itypfb a value not equal to ientre, isolib, ! isymet, iparoi, iparug, iindef but greater than or equal to 1 and less ! than or equal to ntypmx (see values in param.h) to distinguish groups ! or colors in other subroutines which are specific to the case and in ! which itypfb is accessible. In this case though it will be necessary ! to prescribe boundary conditions by assigning values to icodcl and to ! the 3 rcodcl fields (as the value of itypfb will not be predefined in ! the code). ! Boundary condition types for compressible flows ! =============================================== ! For compressible flows, only predefined boundary conditions may ! be assigned ! iparoi, isymet, iesicf, isspcf, isopcf, ierucf, ieqhcf ! iparoi : standard wall ! isymet : standard symmetry ! iesicf, isspcf, isopcf, ierucf, ieqhcf : inlet/outlet ! For inlets/outlets, we can prescribe ! a value for turbulence and passive scalars in rcodcl(.,.,1) ! for the case in which the mass flux is incoming. If this is not ! done, a zero flux condition is applied. ! iesicf : prescribed inlet/outlet (for example supersonic inlet) ! the user prescribes the velocity and all thermodynamic variables ! isspcf : supersonic outlet ! the user does not prescribe anything ! isopcf : subsonic outlet with prescribed pressure ! the user presribes the pressure ! ierucf : subsonic inlet with prescribed velocity and density ! the user prescribes the velocity and density ! ieqhcf : subsonic inlet with prescribed mass and enthalpy flow ! to be implemented ! Consistency rules ! ================= ! A few consistency rules between 'icodcl' codes for variables with ! non-standard boundary conditions: ! Codes for velocity components must be identical ! Codes for Rij components must be identical ! If code (velocity or Rij) = 4 ! one must have code (velocity and Rij) = 4 ! If code (velocity or turbulence) = 5 ! one must have code (velocity and turbulence) = 5 ! If code (velocity or turbulence) = 6 ! one must have code (velocity and turbulence) = 6 ! If scalar code (except pressure or fluctuations) = 5 ! one must have velocity code = 5 ! If scalar code (except pressure or fluctuations) = 6 ! one must have velocity code = 6 ! Remarks ! ======= ! Caution: to prescribe a flux (nonzero) to Rij, the viscosity to take ! into account is viscl even if visct exists ! (visct=rho cmu k2/epsilon) ! One have the ordering array for boundary faces from the previous time ! step (except for the fist one, where 'itrifb' has not been set yet). ! The array of boundary face types 'itypfb' has been reset before ! entering the subroutine. ! Note how to access some variables (for variable 'ivar' ! scalar 'iscal'): ! Cell values (let iel = ifabor(ifac)) ! * Density: propce(iel, ipproc(irom)) ! * Dynamic molecular viscosity: propce(iel, ipproc(iviscl)) ! * Turbulent viscosity: propce(iel, ipproc(ivisct)) ! * Specific heat: propce(iel, ipproc(icp) ! * Diffusivity(lambda): propce(iel, ipproc(ivisls(iscal))) ! Boundary face values ! * Density: propfb(ifac, ipprob(irom)) ! * Mass flux (for convecting 'ivar'): propfb(ifac, ipprob(ifluma(ivar))) ! * For other values: take as an approximation the value in the adjacent cell ! i.e. as above with iel = ifabor(ifac). !------------------------------------------------------------------------------- !
