Hi, Could someone please help on the rectangle function of COMSOL? I tried to apply two thermal pulse onto one surface at two different times. Pf(t)+Pf(t-1). P is a constant. f is an Heaviside function that lasts for 0.1s. However. COMSOL can only recognize the first function and cannot process the 2nd one. Has anyone seen this before? Thank you

I suggest you post your .mph file to the forum. I'm guessing that your model contains a relatively simple error in either the way that you defined the function or the way that you attempted to call it.
