how to manually set time step after remeshing

I am using comsol to simulate a time-dependent Fluid-Structure Interaction (FSI) problem. If I select generalized-alpha method under time-dependent solver node, I can manually set a desired time-step size. But after comsol automatically remeshes my module due to a large deformation, comsol will ignore the setted time step size and run with automatically calculated time step again.
Could anyone tell me how to keep the manually setted time step size after comsol remeshing a FSI model.
Besides, where can I find some information about how does comsol calculate its time step size? I didn't find anything about it in comsol help documents nor online.

Thank you in advance!
