hi,
i'm new with openFOAM (OF) and a little bit confused by all the commands that changed with OF versions. Please advice me how to learn OF from up-to date materials.
In addition i try to run an axisymmetric jet simulation and i cant seem to find enough material. Nevertheless, with code i found in github i managed to construct a case that succeed to run however only for one time step.
Attached code:
