[HFSS] Does HFSS use previous results?

Hi

I am using HFSS and in order to obtain best result. To do that, I try to optimize parameters. For Example, I use 100pF to tune the antenna, than, change it to 150pF.
How does HFSS solve the next one? Does it use results of previous simulation?
What if I change the dimensions?
Lastly, I need a solution for 64 MHz. My structure is not complicated. What do you suggest to increase the speed of solution?

Thanks a lot

Any time you change a parametr of your simulatioon HFSS will restart the simulation from scratch

when you change the cap value, it does not warn you about invalidation of the results!
