Second order time scheme

[fomeh]

Hello guys

Could someone explain to me how to activate the second order time scheme in CS? I can't find this option in the GUI.

Thanks

Hello,

In which version of Code_Saturne?
The solution is probably in user doc.

Hi Jacques,

I'm using 3.0.0.

[fomeh]

According to the user guide of CS, this parameter should be modified via the user subroutine parameters under -usipsu. However when I add

Code: Select all

ischtp = 2

to cs_user_parameters.f90, the simulation crashes without generating any error file. Any comment would be appreciated.

There is no error message in listing ?

It stops after this message:

Could you attach your listing here?

[fomeh]

I've attached.

Do you need my param file and user subroutine aswell?

Tnx
