Hi Everyone,

I am new to comsol (version 4.2) and running into a problem: I defined a global function called generic_pulse_shape_func and I'm trying to evaluate the definite integral of this function (from t=0 to t=50E-9 seconds) and set the value as a global parameter. In global parameters I type in this:

integrate(generic_pulse_shape_func(t),t,0,50E-9)

but the result is not calculated and the text I typed apears orange with a warning: "Unexpected unit of input". Can anyone help me figure out what is going on or how to get around this problem?

Thank you!

In the help files for 4.2 I didn't see a special function for integration. Maybe I'm missing something?
