Which file is read in restart for velocity and pressure?

Hello,
Now I am wondering which files are read for velocity and pressure when we set restart calculation.
I mean that when we select "check point" in GUI, which files of velocity and pressure are refererred in restart calculation?
In future I will use these files for inverse problem, so I want to know this.
Best regards,
Tusbasa

Hello,
Did you check the user guide?
In section 3.9.3.7 Variables saved to allow calculation restarts, you have a detailed description of the saved files in the checkpoint directory and also the variables saved in each file.
Regards,
Luciano

Hello,
As you said, I can find the description for my question.
Let me check just in case.
As far as I understand in Section 3.9.3.7,
"main" file contains variables" value of last time step.
This means, if I need all variables' value at every time step for inverse problem, do I have to use variables' value (such as pressure velocity) in "listing" or "run_solver.log"?
For inverse problem, I will use my code and need variables' value at every time step.
Best regards,

Hello,
If you need values over the whole domain at every time step, I recommend you look at i-situ methods. Writing values at each time step has a high impact on performance, and will fill up your storage very quickly.

Hello,
Do you mean "in-situ method"? or "i-situ method"?

Hello,
Sorry for the typo.
"In-situ" methods.
Best regards,

Hello,
If I need only variables' value of average flow fileld at the las step, where can I get them (velocity and pressure)?
Best regards,

Hello,
In this case, the best is to activate time moments (in postprocessing) for velocity and pressure. They should then appear in the checkpoint/auxiliary.csc file.
