Purpose: ! ------- ! User subroutine. ! Fill boundary conditions arrays (icodcl, rcodcl) ! for unknown variables. ! Introduction ! ============ ! Here we define boundary conditions on a per-face basis. ! Boundary faces may be identified 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. ! Boundary condition types ! ======================== ! Boundary conditions may be assigned in two ways. ! For "standard" boundary conditions: ! ----------------------------------- ! (inlet, free outlet, wall, symmetry), we define a code ! in the 'itypfb' array (of dimensions number of boundary faces, ! number of phases). This code will then be used by a non-user ! subroutine to assign the following conditions (scalars in ! particular will receive the conditions of the phase to which ! they are assigned). Thus: ! Code | Boundary type ! -------------------------- ! ientre | Inlet ! isolib | Free outlet ! isymet | Symmetry ! iparoi | Wall (smooth) ! iparug | Rough wall ! Integers ientre, isolib, isymet, iparoi, iparug ! are defined elsewhere (param.h). 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 0 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 for iv et iw not used) ! -> Specific code and prescribed temperature value ! at rough wall, if applicable: ! at face ifac, icodcl(ifac, ivar) = 6 ! rcodcl(ifac, ivar, 1) = prescribed temperature ! rcodcl(ifac, ivar, 3) = dynamic roughness height ! -> 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 (= impermeable frictionless 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: ! we retain 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: ! we prescribe 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), we define ! - 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, we may use 'iindef' if we 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 we forget 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, en 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, ivar, 3) = rugd ! For other scalars, thermal roughness ! rcodcl(ifac, ivar, 3) = rugt ! 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, we may have for example: ! -> set itypfb(ifac, iphas) = 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). ! 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 ! we must have code (velocity and Rij) = 4 ! If code (velocity or turbulence) = 5 ! we must have code (velocity and turbulence) = 5 ! If code (velocity or turbulence) = 6 ! we must have code (velocity and turbulence) = 6 ! If scalar code (except pressure or fluctuations) = 5 ! we must have velocity code = 5 ! If scalar code (except pressure or fluctuations) = 6 ! we 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) ! We have the ordering array for boundary faces from the ! previous time step (except for the fist time step, ! 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: ! Cell values ! Let iel = ifabor(ifac) ! * Density phase iphas, cell iel: ! propce(iel, ipproc(irom(iphas))) ! * Dynamic molecular viscosity phase iphas, cell iel: ! propce(iel, ipproc(iviscl(iphas))) ! * Turbulent viscosity dynamique phase iphas, cell iel: ! propce(iel, ipproc(ivisct(iphas))) ! * Specific heat phase iphas, cell iel: ! propce(iel, ipproc(icp(iphasl)) ! * Diffusivity: lambda scalaire iscal, cell iel: ! propce(iel, ipproc(ivisls(iscal))) ! Boundary face values ! * Density phase iphas, boundary face ifac : ! propfb(ifac, ipprob(irom(iphas))) ! * Mass flow relative to variable ivar, boundary face ifac: ! (i.e. the mass flow used for convecting ivar) ! propfb(ifac, pprob(ifluma(ivar ))) ! * For other values at boundary face ifac: ! take as an approximation the value in the adjacent cell iel ! i.e. as above with iel = ifabor(ifac). !------------------------------------------------------------------------------- !
