what extra step should i take in doing time-step analysis? i need to do an analysis which involves 300 time-steps, with 100 constants in each time-step. the problem is a multi-scale mass-heat transfer related.
Check out the time-dependent examples, e.g.
examples/diffusion/time_poisson.py (long syntax) examples/diffusion/laplace_time_ebcs.py (short syntax, changing boundary condition nodes)
Basically, just define the time-stepping solver, and if it's a dynamic simulation, add some terms with time derivatives of variables, like dT/dt in the first example above.
What do you mean by "100 constants"?
