Re: Error in compiling subroutines - Code Saturne 5.2

Hello,

Could you also check if gfortran works when run under "salome shell" ?

If it is not related, we would need to modify a salome_cfd file to instrument it, but starting with the simplest test first may be better...

Best regards,

Yvan

Re: Error in compiling subroutines - Code Saturne 5.2

Again: does the "gfortran" command work on your machine now ?

Re: Error in compiling subroutines - Code Saturne 5.2

Hello,

do you have a "gfortran" executable or only "gfortran8" ? This may depend on your distribution.

Could you post your new compile.log ? You might have a similar but slightly different issue if some other tool is missing.

Best regards,

Yvan

Re: Internal coupling and steady state

Hello Luciano, Checking our verification test case, the "steady" case ignores unsteady terms in the equation, but uses the default time-stepping algorithm, so we do not go through the pseudo-steady time step option you used, which explains why we did not notice the issue before... but it is indeed a...

Re: Velocity at the wall

Hello, You used a regular wall model for k-omega, which does not enforce a true no-slip condition on the wall, but only a wall friction (so that the mean velocity in the wall-adjacent cell matches that we would have with a more refined mesh and a true no-slip condition, given the expected velocity p...

Re: Internal coupling and steady state

Hello Luciano,

OK thanks, I'll check that (probably with Erwan's or Martin's help) and get back to you soon.

Best regards,

Re: Internal coupling and steady state

Hello Luciano, Is the top left picture using the modified or unmodified version ? On the right, I do not see the orange curve. Is it superimposed with another ? Which modification did you need to add to the code ? Checking our verification test case, we seemed OK in the steady simulation, but since ...

Re: Compilation error code_saturne 6.0 beta - "no member named 'coeff_send' "

Hello,

This is an error when building without MPI (we occasionally test without MPI, but all our automated tests use MPI).
I just uploaded a new version containing a fix (and others).

Best regards,

Re: user subroutines not executed

Hello, OK good. For your info, if you setup the post-install correctly (see install documentation, but basically amounts to setting a few values in the <install_prefix>/etc/code_saturne.cfg), you can use a batch system directly with the regular Code_Saturne scripts, and use the "code_saturne submit"...
