Hi

could you please give more information? Like the equation, what do you want to do exactly... Otherwise people cannot help you.

hi,

In my case, I want to set the inlet velocity to 0.2m/s and find the optimize outlet pressure. currently, I was used Lagrange method to solve that. so how can I set the equation of the optimization and calculate the velocity error into icofoam?
