Modification 2025-03-31 that allows you to specify the initial yield stress as a function of location.
The program works as before if this is not the case: a setrun.py file that was valid for the release v1.0.2 will still be valid for the current version.
However, you can now set an integer flag "i_use_var_tau_y" to 1 to impose a spatially varying initial yield strength using absolute values, and to 2 to impose a spatially varying initial yield strength using "relative values" (i.e. a map of values 0 < val < 1 such that tauy = tauy_r + val*(tauy_i - tauy_r) ... ) These maps of initial yield strength are specified using variable name "fname_tau_y". Examples of setrun.py files and distribution files are found in the directories "absolute_initial_tauy_example" and "relative_initial_tauy_example".
