Default transonic simulation with OpenFoam
Posts: n/a
Hi, I am testing OpenFoam for our research work. I am interested in steady state solutions for flow over aerofoil. The compressible solvers in OpenFoam are transient and are sensitive to choice of timestep and hence consume more CPU time. I am wondering if it is possible to do a multigrid acceleration as conventionally done for euler flows. Also, is it possible to set the timestep constraint in OpenFoam using a CFL criteria than specifying the time step directly?

Thanks in advance for your help.
