Change mesh from one simulation to another

[krb-nantes]

Hi everybody!
I need to simulate a Zry cladding oxide spallation, making the oxide grow before spalling. So, I planned to first do the oxide growth on a whole block until the desired thickness and then, make a second simulation where I would remove part of this block (this would be the spalled part), but I wanted to use some data from the first simulation, as the temperature profile, by setting the "restar_file_base" on [Problem] block, however, I receive an error doing this, I must use the same mesh for both.
So, is there a way that I can make modifications in the mesh on the second simulation and use the data from the first one?

Hello

You ll want to use the SolutionUserObject to do that.

Alternatively you can load the other mesh in a MultiApp and transfer information from there

I was able to load the variable values and use as IC for the second simulation, however I could not retrieve the oxide thickness, because it is set as AuxVariable, and I cannot set IC for AuxVariable.

use an auxkernel executed on INITIAL for an IC of an AuxVariable
