Chris Kriel is on a distinguished road
I am running some simulations using Adaptive Mesh Refinement. It works extremely well. However, I sometimes have the following problem:

After the mesh has been refined I sometimes stop the simulation to look at results. Sometimes, when I want to continue the simulation, the option to 'Continue' is greyed out and the only option is to start a 'New Calculation' and with that the 'Mesh' option is automatically ticked and greyed out, so the only option is for the solver to create a new mesh. All the parts in my model are fixed/mated, so it is not that a part has moved that the solver picked up with the only option to remesh.

So my questions:
1. Any idea why this sometimes happens?
2. If this happens, is there a way of forcing the solver to use a specific mesh, i.e. the previously created adaptive refined mesh? I.e changing some environment variables or editing a text file or something?

Thank you
