Extracting end values and use them as initial values on the same geometry in new simulation

Please login with a confirmed email address before reporting spam

Hi,

My problem is the following:
I have a certain rectangle A (2D) with a uniform initial temperature. On top this rectangle A there is another rectangle B with also a (different) uniform initial temperature.

After computing the Time Dependent solution, the temperatures of rectangle A and B are not uniform anymore.
Now, I would like to extract/save the temperature end values and use them in a next simulation as initial values where I add another third rectangle C to the geometry.

To do so, I have two m-files: one with rectangle A & B and one m-file with rectangle A, B & C.

The question is: how can I (via the Matlab Livelink) use the end values of rectangle A & B as initial values of rectangle A and B in the next simulation?

I know the function:
T = mpheval(model,'T','dataset','dset1');
which gives me the end temperature, but how can this be used a initial value for the another simulation (geometry stays the same!)?


I hope one of you can help,


Regards,

Peter
