Hello,

To select rotating cells, you can either use a geometric criterion (see selection criteria in user documentation), or define a volume group in SALOME (which is the recommended option).

Hello, I did not find anything obviously wrong with your mesh so far, but as cells are very thin in the joining area, it is difficult to zoom on the zones where issues can be seen. To further analyze you mesh, a solution would probably be (before joining) to cut just a small piece of the mesh (both ...

Hello, Could you try setting the same values for CompC as mpiCompC (mpicc) and compCxx as mpiCompCxx (mpicxx) ? Actually, first trying only setting compCxx = mpicxx would be interesting. I do not use the automatic installer often, so I would not be surprised that issues are du to using compCXx where...

Hello, Which of the efforts to use really depends on what you are computing (again, refer to the definition). In any case, all surface efforts given by Code_Saturne are given per surface unit , so you don't need to divide them by the surface (but rather multiply them by the matchin face surfaces to ...

Hello, The guide needs to be updated, as both Syrthes and Code_Saturne need the PLE library to be installed first. As that library is part of Code_Saturne , it is easier to simply install Code_Saturne first. Another option is to install PLE first, by running a configure/make/make install sequence re...

Hello, You may also need to first apply the "extract blocks" filter in case you have output both on volume and boundary meshes. Otherwise, are the glyphs based on velocity ? As this is the only vector field in most cases, it should be the default, but it may be safe to check. Regards, Yvan

Hello,

Under ParaView, to get glyphs right, you need to apply the "cell data to point data" or "cell centers" filter first. Otherwise, glyphs all point in the same direction, as in your screenshot.

Hello, You need to go back to the definition of the skin friction coefficient. Using the efforts and face normals, you may integrate the efforts (or their components over a given direction), then divide them by the reference surface to obtain the friction coefficient. This type of operator could in ...

Hello,

Could you post your Syrthes setup.ini and Code_Saturne config.log ? Did you build Syrthes after Code_Saturne, or at least its PLE sub-library ?

Hello, I am not sure about your syntax. Do you mean --with-salome=/home/ffan/salome-meca/V2014_2 in the configure step ? This is strange, we often build with SALOME with no issues. I have tried building with SALOME-MECA also in the past, with no issues. Is our build of SALOME-MECA 32-bit or 64-bit ?...
