Hello everyone, I am looking for a way to calculate the principal strain rates in ASPECT, similar to the principal stresses obtained in the postprocessing output. I have been unable to find an option for principal strain rates. Could anyone guide me on how to achieve this? I am currently using ASPECT for my PhD research.
@sharmamd That might not be implemented yet, but since there is a postprocessor for the stresses, take a look at how that is implemented – and then copy it to create a postprocessor that computes the principle strains.
We’d of course be excited to take a patch!
Best
Wolfgang
@bangerth Thanks, I will look into it.
