A general question about convergence issue

I'm doing research with Comsol 5.3 fluid flow interface. I used couple geometry parameters such as radius of a cylinder, the angle of a domain relative to the others, etc. When I try to change those parameters and build the geometry, it usually mess up the domains I set up earlier in "delete geometry" and "partition domain". This is one problem. Another one is: when I try to calculate different results from different parameters, Solver doesn't converge. And I rebuild everything in a new file exactly the same as previous ones except this time I start with the new parameter I want. Then it works. I don't know why. Is this happening to you guys?
Sincerely,
Xu Xu
