Getting a matlab function to work within Comsol pde?

Please login with a confirmed email address before reporting spam

Hi,

I have 1D general form PDE (g) with dependent variable u. Gamma(the flux term) is defined as an input function - [K]=function(u) from Matlab. This function is a numerical code we wrote that has u as input and (double) K as output. When I define function(u) in Comsol and plot it, it generates the correct plot, meaning my Matlab file path is correct, and Comsol can connect to it and find the right function. When I put function(u) as Gamma term the solution does not seem to be using the function at all.

Any ideas on what I might be doing wrong? What is the correct way of inserting a matlab function into comsol?

Thanks.
