’Validation of the dislocation transport equations‘ by Christoph Kords, nonlocal

[cherry12306]

Hello, I am a beginner in damask and I am trying to reproduce chapter 5 Validation of the dislocation transport equations of Christoph Kords' PhD thesis. I am having 2 problems and I hope you can give me some guidance. First of all, regarding the dislocation source being at the origin and the positive edge dislocation moving in the positive direction of the x-axis, and the negative edge dislocation moving in the negative direction of the x-axis, the dislocation didn't move after I ran my model, I will attach my material.yaml file below, as well as a schematic of my model. Secondly, regarding the elastic matrix, I did not find the shear modulus and poisson ratio in the isotropic example, and I did not find the dislocation mobility in the nonlocal constitutive law. I will attach all my files below, and I hope I can get your answer. Thank you very much.

I don't recommend beginners to start with the nonlocal model because of its complexity.

Thank you, but my form of force requires me to use this constitutive law, I'll do my best to try again.

Then I suggest that you start learning DAMASK with simpler constitutive models and switch to nonlocal only after you became a DAMASK professional.

Thanks for the suggestion, I've tried Phenomenological constitutive models before, and nonlocal is indeed a bit harder than the previous one. I need to learn more.
