I am using the PDE module of COMSOL multiphysics v3.5a.
the PDE, coefficient form/time-dependent analysis.
now, I am solving one equation. The coefficient of my equation is a function of the COMSOL calculation results of the previous step. That is, when I am calculating the variable of n+1 timestep, the coefficient of my equation is a function of variable value of n timestep.
please tell me how can I achieve this?
I heard that the prev operator ( prev(expr,i) ) can satisfy my purpose, but i don't know how to use it??
please help me.
thank you very very much!!
