Hello everyone!
I am a newbie who seeks help in COMSOL.
I have simulated a laminar flow in an annulus using direct solvers. The results match well with the problem (taken from Bird Stewart Lightfoot). I am trying to observe if changing the solver I have used will bring about any change in simulation time, easier convergence,etc. However, I am not sure where to look for these details.
Could you help me find where any changes, due to changing solvers, may be possible?
Also, I find a convergence plot laid out while using DIRECT solvers. It shouldn't be there, right? I have read that the solution is generated 'at once' using direct solvers using matrix method.
Thank you for your time.
