Some questions regarding PFM on raccoon

[ghost]

Hello,

I have some questions regarding phase field modeling using the raccoon app:

1. Assuming we are using the traditional Allen-Cahn formula \dot{d}=\frac{1}{L}(\frac{\psi}{d}) where d is the damage and the phase field variable, psi the free energy and L is the mobility, I understand how d is defined and how psi is defined but I do not find mention of the mobility and the viscosity anywhere.. could you please guide me on this?

2. For the free energy, I see that in the given tutorials psi is usually function of the active elastic energy and no mention of the inactive elastic energy is there a reason for this? I have tried to add psie_inactive to the psi formula in the input file by adding psie_inactive as an auxvariable in the fracture.i file and adding it to the transfer block in the elastoplasticity.i file and by defining it again in the header file of the SmallDeformationIsotropicElasticity.h but I am getting the error 'undefined psie_inactive', how can I proceed to fix this?
   Thank you.
