Re: Restart not taken into account in v7

Hello Yvan, Thank you for your analysis, I understand that you can't help more precisely without a more detailed debugging. And I don't exclude some simple stupid error from my side... Anyway, I tried to uncheck the "use unmodified checkpoint...", but no improvement. And yes, I double chec...

Re: Restart not taken into account in v7

Hello Yvan, Yes, I use the Default partitioning. I have just made a test with other partitioning methods, but nothing changes. Yes, the crash occurs before the partitioning file is written... I am using v7.0.2. I see that it does not seem to be linked to the restart, but actually the calculation wor...

Re: Restart not taken into account in v7

Hello Yvan, I see what you mean. I actually found a forbidden memory area access error, reported in the error file (I have two error files, this is reported only in one of the two): SIGSEGV signal (forbidden memory area access) intercepted! This could be a sign of the source of the issue, but the se...

Re: Mixture multiphase model

I forgot to add that of course you will then have to modify your properties (density, viscosity...) as a function of the scalar.
This could be done in the cs_user_physical_properties.f90 at the time, I don't know with the current version.
Best regards, Daniele

Re: Restart not taken into account in v7

Hello Yvan, I forgot to update you about this issue: indeed, imposing the restart through the cs_user_scripts.py works! So thank you very much for this tip! However, I sometimes encounter the following error with restart (I am always with v7): Reading file: restart/mesh_input.csm Finished reading: r...

Re: Mixture multiphase model

Hello, I actually did this in the past, with v5. If you want a mixture two-phase model, the easiest way is just to add a transported scalar. You can add scalars directly in the GUI. The scalar will represent your void fraction (or rather the mass fraction in CS). Then, you can add a drift velocity t...

Re: Free memory constantly decreasing

Hello Yvan,

Thank you for testing and correcting the issue.
I am not experienced with Github, I saw the commit where you fix the bug on branch v7.0: does it mean that if I clone v7.0 and compile it, I will have the code with the bug fixed?

Thank you very much for your help.
Best regards,
Daniele

Restart not taken into account in v7

Hello, In v7.0.2, I have noticed that for some cases I cannot manage to tell the code to do a restart. I select restart in the GUI, select the correct checkpoint directory, but the code seems blind to my set-up and always restarts the simulation from zero. The ISUITE=0 appears in the listing, which ...

Re: Output forces on surface

Hello, It is a user routine that you need to add in the SRC directory. I suggest you to have a look at the examples of such routines on the webiste or in the GUI. Anyway, I have not used v8 yet, but I think they removed all fortran routines, so you will need to switch to C. The procedure remains the...
