Re: just start with a known solution for first time step

Markus,

1st create a new study. In the new study...
Under Step 1: Time Dependent, in the Settings window, expand Values of Dependent Variables.
Check Initial values of variables solved for
Method: Change Method to Solution
Study: Select the Study that you would like to reference
Selection: Select the Time step from that study that you would like to use. In your case, use "Last."

Re: just start with a known solution for first time step

Thanks Josh,
I know this possibility.
But I was not sure if your solution does not at any time following step refers in the approach first to this initial solution. In my model, it initially looked like this. Even if I not pick the "last" time step, but "automatic", it works exactly the same. So I was really confused.
Another solution was than more familiar to me:
You export the final solution (eg in case of 2D as xy-matrix) and imports it as int1(x, y) and use it as initial variable and repeat the same study. It works like your proposal, Josh.
Best Regards,
Markus
