Does anyone know what 20 denotes in command convectParallel(Mesh, [u1, u2], -dt, c, 20) ?
It is a safety parameter.
Many thanks. So I will keep it in case this command won’t work.
Sorry, I want to ask a further question, if I want to change this parameter, if it is more better if I make it larger or smaller?
It’s problem dependent. In general, you should not use this function.
Thank you very much for your reply. I think it’s unreliable to use convect command to parallelize NS equation. So I will transfer to use Newton method.
