Hello,

I would like to know if it's possible to approximate a curve by an exponential one determine and plot it on Comsol.

Thks

Hi
you can import the data into a interpolation file, then create an exp function and optimise the parameters to fit in a means square way to the data set, but it's somewhat an overkill to use COMSOL for that, you can also ask the interpolation function to approximate yor data, but I believe its limited to poloynomials

Good luck
