FSI internal coupling and sub-iterations
Posted: Wed May 22, 2019 12:16 pm
Hello,
I am dealing with FSI internal coupling calculation within Code_Saturne and I would like to know how to change the force relaxation term used in the sub-iterations which maximum number is driven by the variable NALIMX ? According to the documentation, the variable CFOPRE is supposed to do so but it does not seem to work in my simulations: I am indeed dealing with FSI calculation with a relative high value of the ration added mass/structure mass and I need to reduce the relaxation term in order to stabilize the calculation.
Thank you in advance for your help.
Best regards,
So_nuc
