How to calculate the "crack propagation speed" in the cohesive zone model?

10 October 2019 1 10K Report

Damage parameter is used in the Cohesive Zone Model to study the crack propagation. Is there a relation to the "crack speed" to the "damage parameter"? What could be the best way to calculate the crack speed preferably in COMSOL?

How to make "time step to store output" variable in Comsol Multiphysics?

In time dependent study one can define the range like (0,0.1,1) the solver stores solution at each 0.1 interval. One can also define steps like range(0,0.1,0.9),range(0.9,0.01,1) it changes steps...
