Adjust FEM model (Beginner)

[hpon]

Hi,

I'm working through some FEM tutorials, and things are mostly going well. But unfortunatelly, the study material has left out one essential thing: Howto go back and make changes in an already executed model?

The most imediate issue here is that all settings seem to be locked due to the existance of a solution. How do I unlock executed models for modifications?

It seems like one has to delete each object manually and then replace them with new ones, instead of simply modifying them in a straight-forward manner. Is this true?

For instance, if I want to change the mesh. Should I then first delete the results file and then mesh and then recreate the mesh again? I hope not.. How do I make changes more time-efficiently?
