Hello all, I was wondering if some automation in the application of boundary conditions was possible. My problem involves repeatedly reducing exit pressure till the exit mach reaches a certain value. If I could simply iterate the same till it happens, it would help a lot. Maybe write a code in the boundary conditions or solver where it iterates for each pressure value till convergence and if exit mach is not matching required mach, reduce pressure by a certain amount and then continue.

Alternately, I could go for a transient analysis with pressure varying with time in the boundary conditions. I can give timesteps and do the same. I would like to know in which way should I go about it.

transient simulation probably will take more time, ofc everything depends on your settings.

you may control almost everything using TUI commands
write them into scheme, however, code requires some knowledge from you.
