problem in convergence
I am doing blood flow through stenosed artery. I consider the arterial wall as porous domain
wall has multiple layers which has different porosity and permeability
I have written permeabity and porosity as a function of r
it is steady state analysis. I am facing the convergence problem .I need your help
Use a much smaller timestep to start off, and possibly local time scale factor (set it to about 5). Run that for a while until it starts to converge, then switch back to physical time scale with a larger time step to convergence.
These are all standard tricks for getting convergence, read the documentaton on "Obtaining Convergence".
