Hello,Luciano

Whether Code_Saturne can be achieved wo fluid modelling? The attachment is the user subroutine I mentioned earlier. I hope you can give me valuable advice.

Best wishes，

Hello,

In the "cs_user_boundary_conditions_ale001.f90" file you define "itypfb(ifac,ilelt) = ientre" and you fill all the icodcl and rcodcl arrays. As it is mentioned in the user documentation

In the case of standard boundary conditions (see §6.4.1), it is sufficient to complete itypfb(ifac)
and parts of the array rcodcl; the array icodcl and most of rcodcl are filled automatically. For
non-standard boundary conditions (see §6.4.2), the arrays icodcl and rcodcl must be fully completed.

So, you get an error during the execution. If you comment the line "itypfb(ifac,ilelt) = ientre", the BC is imposed correctly.

I attach a case using this subroutine, I modify the values of some variables in order to used an existing mesh.

About multiphase flow, EDF has a specif solver called NEPTUNE, you can check the information in the code saturne web page. UPDATE(
