Restart a dynamic refined simulation from a different time-step -- CFD Online Discussion Forums

Andrea_85 Senior Member Andrea Ferrari Join Date: Dec 2010 Posts: 319 Rep Power: 16	Hi All, Is there a way to restart a simulation with dynamic mesh refinement (interDyMFoam) from a time different from zero, and prevent openFoam from refining again a mesh that has already been refined in the previous steps? If a simply restart the simulation from a time different from the 0-time, openfoam takes the already refined mesh as the "base" mesh and refines again. i would like to avoid this. I though about using mapField utility to map the "refined" fields at a certain time back on the base mesh (not refined) and restart the simulation from there but i was wondering if there is a quicker way to do that. best, Andrea
