Variables

integer nscamx
 maximum number of scalars solutions of an advection equation, apart from the variables of the turbulence model $ (k, \varepsilon, R_{ij}, \omega, \varphi, \overline{f}, \alpha, \nu_t$) , that is to say the temperature and other scalars (passive or not, user-defined or not) More...
 
integer nvarmx
 maximal number of variables = nscamx + 12 (u,v,w,P,Rij,e,alp) More...
 
integer ntypmx
 Maximal possible boundary condition types. More...

integer iparug
 
integer iesicf
 if itypfb=iesicf: imposed inlet/outlet for compressible flow (for example, supersonic inlet). More...
 
integer isspcf
 if itypfb=isspcf: supersonic outlet for compressible flow. More...
 
integer isopcf
 if itypfb=isopcf: mixed outlet for compressible flow with a given pressure. More...
 
integer iephcf
 if itypfb=iephcf: mixed inlet for compressible flow with given total pressure and total enthalpy (reservoir boundary conditions). More...

integer i_convective_inlet
 
integer nestmx
 maximal number of valuators for Navier-Stokes More...
 
integer iespre
 Error estimator for Navier-Stokes. iest = iespre: prediction, (default name: EsPre). After the velocity prediction step (yielding $\vect{u}^*$), the estimator $\eta^{\,pred}_{\,i,k}(\vect{u}^*)$, local variable calculated at every cell $ \Omega_i $, is created from $\vect{\mathcal R}^{\,pred}(\vect{u}^*)$, which represents the residual of the equation solved during this step: $\vect{u}$ and $ P $:

\begin{eqnarray*} \vect{\mathcal R}^{\,pred}(\vect{u}^*) & = & \rho^n \dfrac{\vect{u}^*-\vect{u}^n}{\Delta t} + \rho^n \vect{u}^n \cdot \gradt (\vect{u}^*) - \divv \left((\mu+\mu_t)^n \gradt (\vect{u}^*) \right) + \grad(P^n) \\ & - & \text{rest of the right-hand member } (\vect{u}^n, P^n, \text{other variables}^n) \end{eqnarray*}

integer iesder
 Error estimator for Navier-Stokes. iest = iesder: drift (default name: EsDer). The estimator $\eta^{\,der}_{\,i,k}(\vect{u}^{\,n+1})$ is based on the following quantity (intrinsic to the code):

\begin{eqnarray*} \eta^{\,der}_{\,i,k}(\vect{u}^{\,n+1}) &=& {|\Omega_i|}^{(k-2)/2} || \divs (\text{corrected mass flow after the pressure step}) - \Gamma||_{{L}^{2}(\Omega_i)} \\ &=& {|\Omega_i|}^{(1-k)/2} | \divs (\text{corrected mass flow after the pressure step})- \Gamma| \end{eqnarray*}

. More...

 
integer iescor
 Error estimator for Navier-Stokes. iest = iescor: correction, (default name: EsCor). The estimator $ \eta^{\,corr}_{\,i,k}(\vect{u}^{\,n+1})$ comes directly from the mass flow calculated with the updated velocity field:

\begin{eqnarray*} \eta^{\,corr}_{\,i,k}(\vect{u}^{\,n+1})= |\Omega_i|^{\,\delta_{\,2,k}}\ |div (\rho^n \vect{u}^{n+1}) - \Gamma| \end{eqnarray*}

. More...

 
integer iestot
 Error estimator for Navier-Stokes. iest = iestot: total, (default name: EsTot). The estimator $ \eta^{\,tot}_{\,i,k}(\vect{u}^{\,n+1})$, local variable calculated at every cell $\Omega_i$, is based on the quantity $\vect{\mathcal R}^{\,tot}(\vect{u}^{\,n+1})$, which represents the residual of the equation using the updated values of $\vect{u}$ and $P$:

\begin{eqnarray*} \vect{\mathcal R}^{\,pred}(\vect{u}^*) & = & \rho^n \dfrac{\vect{u}^*-\vect{u}^n}{\Delta t} + \rho^n \vect{u}^n \cdot \gradt (\vect{u}^*) - \divv \left((\mu+\mu_t)^n \gradt (\vect{u}^*) \right) + \grad(P^n) \\ & - & \text{rest of the right-hand member } (\vect{u}^n, P^n, \text{other variables}^n) \end{eqnarray*}
