Hi all, Octavio you should be able to restart the simulation from any .chk file or directory that is stored inside your case folder. The format for using a file or directory with name restartfile.fld(for example) should look likes this: <FUNCTION NAME="InitialConditions"> <F VAR="u,v,p" FILE="restartfile.fld" /> </FUNCTION> And should be placed inside the <CONDITIONS> … </CONDITIONS> section of your session file. This example can be directly applied for a 2D flow with flow variables u, v, p. Also, don’t forget to match the variables of your simulation with the ones that are specified next to the VAR name. I hope this helps!

Hi Nektar community, in your experience, is it possible to start a case from a .fld or .chk file that has already been running but for some reason something stopped it? (Maybe a blackout or some sort of inconvenience) I've used the: <Expansion> <F FILE="restartfile.fld" /> </Expansion> But it doesn't seem to work. Any info will be helpful and highly appreciated. _______________________________________________ Nektar-users mailing list Nektar-users@imperial.ac.uk <mailto:Nektar-users@imperial.ac.uk> https://mailman.ic.ac.uk/mailman/listinfo/nektar-users
