Default Step from coarse mesh to extra/extremly fine mesh

shizuka is on a distinguished road
Hi everyone,


For a thermal fluid multiphysics problem, I want to perform a mesh convergence study. I'd also like to make use of the computed solutions as an initial condition for the next finer mesh. In other words, in step 1, I'll compute with a coarse mesh. In step 2, I then move on to compute a normal mesh based on the solution I got from step 1.


I'm not sure how to do it. Do I need only specify the "initial values of variables solved for" under "Values of dependent variables"? or do I need to specify the "values of variables not solved for" as well?


Thank you for your help in advance!
