We are running a model where we take a subset of a large 3D model, rotate it, and restart it. We can do this fairly easily from a time = 0 model with no mesh refinement criterion other than depth dependent setting. We can take subset from paraview, do some postprocessing, re-mesh and interpolate onto a new grid and then make an ascii file that ASPECT can read (following instructions from the manual and cookbook examples).
However, it is more difficult, and a lot messier, when trying to do the same procedure after Time = 5 Myr (for example) rather than Time = 0. The grid is no longer nice and regular as it was at time 0, which makes it more difficult eventually plot onto a new grid.
I thought I would message the forum to see if there is any way to take an irregular grid from paraview and and repackage into the appropriate restart.mesh* files to then restart a modified model.
Basically, the same question asked in another way would be: is it possible to manipulate the restart* files and then repackage and “restart” a new model?
I hope that is clear, thanks for you help.
