Hello there.
i have a very gerneral question related to solving the models. My question is that when i make a model and then i start to solve the model and then i realise that i have to make some more changes and i cancel the simulation while it is in process, then i make all the necessary adjustment and then press the solve button again, then will the comsol start to calculate the solution right from the beginning or will it take the previous value of the solution that i stopped and take it as an initial value and then continue to slove the modle with the new changes. Plz help me in the regard.
Thanking you
Yasir

Hi Yasir,
If you press cancel, it is like you erase all the solution history. If you hit stop (on the time solver), your solution stays, but you have to tell the solver manager to use it as initial condition (current solution).

Hi Danial
Thanks alot for the tip. i have another question also what if i run a simulation and get the results and then i go back to sub domaine setting and made some changes and run the simulation again. will the previous results effact the current simulation..
Thanks again in advance....

it depends on the configuration of your solver manager. (=! icon)
Normally it will not affect it, unless you have the current result set as initial conditions for the next one. In that case, the only problem that can occur is that you have modified the model so much that your initial conditions (previous results) are too bad as a startup for the new one.
