Hi everyone,
In my project, I would like to do THM simulation with three sub-cycles. There are HM coupling, TH coupling and HM coupling with certain time ratio of three cycles. Firstly, I use 100 mechancial substep to do simulation.
I noticed that after mechaical and thermal balance. The time ratio of fluid time (by fluid.time command) and mechanical time (by mech.time command) become much less than 100. To speed up simulation, is it reasonable to substitute mechanical substep with this value? If the answer is not, how to determine reasonable substeps with program information I can get?
Thank you all.
