Hello,

I want to use the NREL solar spectrum (https://www.nrel.gov/grid/solar-resource/spectra.html) data in my COMSOL simulations. I am able to import the data into an interpolation table (name is root.int1), however I am not sure how to integrate it. I have tried to do:

integrate(int1,x,lower, upper)

however COMSOL cannot recognize int1 as the interpolation name. Any suggestions would be much appreciate.

Hello Gabriel,

If int1 is a function, you call it with the argument x by typing int1(x), not int1.

Best,

Jeff
