Thank you so much. I appreciate it. It is now worked out! Also, I want to mention here one thing: With the values of the non-Schmid factors given in the example of plastic material parameters for dislotungsten_W i.e., a_nonSchmid_110: [0.0, 0.56, 0.75], the simulation is not getting completed and stopped in between with some error. But, when I used some lower values for example a_nonSchmid_110: [0.0, 0.2, 0.25], it worked perfectly fine.
