Hi, I'm trying to reconstruct a model of cytokinesis in this paper

I've tried axisymetric model in COMSOL using the remesh of a single static step in the adaptation and error estimate as the following. However, I have very limited control of the remesh configuration, only the maximum element number. I'm wondering if it's possible to have several criterions for remesh like the maximum and minimum element size of the remesh? https://ibb.co/nn99Oe The figure after manually adjust the range of value is like this, https://ibb.co/k1Y0wz

Another critical problem is I don't know how to do multiple static steps that inherit the stress and strain from the previous remeshed step so far. I've found a stress free nodal update here, but what I want is to inherit stress and strain from the original configuration and keep each analysis in a static sense. I don't want a time dependent physical problems. Could anyone give me some advise about how to do that?

One of the point I found is that for static problem, when I disable the BC's by modifying the physical model tree, COMSOL always just report error, " - Feature: Stationary Solver 2 (sol1/s2)". My COMSOL window setting is like this. This doesn't happen in the time dependent analysis when I play with the heat transfer problem. Does anyone know what's wrong with my setting? How to do multiple static analysis steps use the remesh to update the mesh at each step while inherit the stress and strain in previous step as initial conditioins. Please help and let me know, thanks.
