Hello All,

I'm trying to fit parameters to my model (using some known experimental values), the thing is that it's not computationally cheap to evaluate. I have a voltage source and all the model does is to calculate the distribution of the potential in space. I was wondering if it's possible to restrict the calculations to only solving at the points where the experimental values are defined, and if that would even speed it up to any degree?

Thanks,
Aaron R. Shifman

The potential is dependent on the surrounding potentials so you have to evaluate it everywhere. But maybe you can reduce your mesh size or the number of dimensions of your model to decrease computational speed.
