Hello, Thanks for your reply Yvan, it was really helpful. I achieved to print what I wanted for each iteration with : fprintf(chargecsv, %e %s %e\n", charge_bas,";",charge_haut); I would like to know how to print also the associated time step using the double variable t_cur. I tried t...

Hello, We are facing the same problem : we launched transient simulations restarting from frozen rotor cases and during the calculation (sometimes after 1600 time steps, sometimes after 6 time steps) the job is aborted with the following message. We've tried to change the joining functions from 0.1 ...

Hello, Thank you for your answers. "Where you print data into the listing, you could as well also print it to another file of your choice, which makes extracting data simpler." We would like to do this precise operation but we are wondering how to do it : which function should we use and w...

Hello, Thank you very much for all those precious informations. We have managed to print coherent total head results (in regards to the results we obtained on previous ANSYS simulations) into the listing and we would like to extract those numbers into a CSV file for each time step. Do you know if th...

I found out the reason why the programm was crashing before it started : it was coming from my anti-virus (Avast) which was blocking the calculation. After disabling it, the calculation runs without any problem.

Best regards,

Valentin

Dear Yvan, As you told us we built a file following the cs_user_extra_operations_turbomachinery.c in the example directory. We only kept the headers and the calculation of turbomachinery head. We then uploaded the file into the SRC folder and ran the calculation through the Code_Saturne GUI. We face...

Dear Yvan,

Thank you for your prompt answer, I'll check this out and try to compute it.

Dear experts, I'm currently simulating a flow through a centrifugal pump. I would like to compute the difference of total pressure between the outlet and the inlets (in my case there are two inlets). The total pressure is defined by TotalPressure=Pressure+0.5*density*mag(Velocity)² Is it possible to...

Hello, Thank you for your answer. Indeed we use SALOME to create our meshes, we tried to export them into med files but we still face problems. By lurking through the Documentation part of Saturne website we have noticed that people often use .des meshes. Which software should we use to open and/or ...

Hello, We are learning how to use Salome and Code_Saturne on simple geometries. We managed to run a convergent simulation using a unstructured mesh (Netgen 3D algorithm on Salome). Then we tried to run another simulation using a structured mesh (Body Fitting with constant spacing on Salome) but we f...
