I have a quick question.
In the material model, I have three properties which are upper crust, lower crust, and mantle, respectively.
I’d like to impose diffusion and dislocation creep for rheology.
For the upper and lower crust, I’d like to impose dislocation only while I’d like to impose a composite model for the mantle.
This is capable of ASPECT using the viscoplastic or diffusion and dislocation model?
In my knowledge, diffusion creep is dominant in deeper depth so that’s why I’d like ot only consider dislocation for crusts. I am wondering It is proper assumption or not?
