Set starting point for stationary study comsol

Please login with a confirmed email address before reporting spam

I am using ht in solids and fluids coupled with laminar flow. I started stationary study, and i saw that in first iteration Temperature of probe 1 and probe 2 are 215 degC and 205degC. I knew that they should be around 135degC and 125degC.

How can i speed up simulation by defining some initial values for solver to take?

Frist Comsol solve stationary study. Than i change my model a little. That change is not new geometry or new mesh or something like that. Its same model with some constants changed in model (heat flux coefficient, emissivity, etc). I expect that the final results does not change drastically. How can i start simulation of changed model from starting point which is final result of previous model simulation?

Is it possible for solver to take some part of the results from previous simulation? Lets say if i change inlet boundary condition to open boundary, i want that my solver at least takes all the temperatures from last solution.

Thanks.
