Where is the interface energy G_c set for the ductile damage model in DAMASK3.0-alpha3? I have seen the critical energy release rate or interface energy G_c in almost all DAMASK damage models, but the anisotropic brittle model and the toughness model only have the settings of critical load g_crit and critical displacement s_crit? And what is the function of the parameter damage diffusion D?

Absence of G_c in Ductile Damage Model:Despite reviewing the related source code and material configuration files within DAMASK, I haven't been able to locate the parameter G_c for the ductile damage model. The material configurations I've been using specify only the critical load parameter g_crit. I have attached the relevant files for reference. Could anyone guide me on where to find G_c or how it is typically incorporated in DAMASK? Relationship Between g_crit and G_c in Anisotropic Brittle Damage Model:Based on previous discussions, the anisotropic brittle damage model uses g_crit (critical load) and s_crit (critical displacement). I'm trying to understand how these parameters relate to G_c and if there's a way to convert between them. I've consulted numerous sources and even looked into DAMASK version 2.0.3, but the specifics regarding G_c remain unclear.

Thank you for your guidance, which has been very helpful. However, I have a few issues that still need clarification:
Your insights into these matters would be invaluable, as these parameters are critical for the accuracy of my simulations. Thank you for your time and assistance.
