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 at 0.9s from 0.1s to 0.01s interval. But these examples are for predefined steps. I want to store the output based on the gradient of an output variable. Is there a way to define this in Comsol?
