Re: Periodic Boundary Conditions and CGNS
Hello, I was not aware that ICEM exported HDF5-based CGNS files with an HDF5 extension instead of CGNS (but then again, ICEM have done strange things in the past, such as cheating on the CGNS version number)... The .hdf5 extension is also used by other formats (such as the Salome Platform's study fi...

Re: Periodic Boundary Conditions and CGNS
Hello, I recommend exoporting the file as an unstructured file: though the reader may handle both, unstructured is more natural, and can handle boundary conditions at faces, not nodes, which requires less conversion steps. For the crash, using periodicity incurs a mesh joining step, which is where t...

Re: Wall shear stress calculation
Hello, In your code: f(iturb.eq.42.and.idries.eq.0) then tau = romc*uet**2 tau0 = 0.0d0 uet0 = 0.0d0 if (ntcabs .gt. 3600) then tau0 = tau0+tau uet0 = uet0+uet endif usertau(ifac) = tau0 userutau(ifac) = uet0 endif you are resetting tau0 at each time step, even when you are trying to accumulate thin...

Re: Fatal error (divergence) solving for Enthalpy
Hello, I won't have the time to look at this before a few days (though other members of this forum might). Did you follow most of the troubleshooting recommendations in the documentation section of this web site ? I'm especially thinking of the time step and CFL, because in may cases, electric arcs ...

Re: Wall shear stress calculation
Hello,
Could you please follow the forum usage recommendations and post the complete user files ? I suspect you forget to add a "save" attribute, but can't check with just a snippet.

Re: Wall shear stress calculation
Hello, There were some fixes since 3.0.3, so I really recommend upgrading to patch release 3.0.5 (3.0.6 should be released with 2 or 3 weeks). Did you call the "init_user_module" somewhere after reading the mesh but before the time loop (for example, in cs_user_initialization.f90/usiniv) ?...

Re: Turbomachinery and mixing planes
Hello, There are several threads on this Forum from about 6 months ago relating to turbomachinery cases, which may help you get started. They relate mostly to version 3.2, but things have not changed too much in this regard since (except turbomachinery cases may now be handled using the GUI). I can ...

Re: Troubles with Pulverized coal and slagging TUTORIAL
Hello, To avoid the "enthalpy" error, you should edit the user law for initialization, and replace temperature with enthalpy. Still, trying this, you may have other crashes later on. The GUI has some amount of automatic updating from 1 version of the code to another, but it is not quite co...
