Hello,
I would like to give a pulsed concentration to my model. Therefore I created a rectangle function rect1.
Then I would like to declare my concentratin c_in as variable as rect1(t[1/s])*0.1 Unfortunately comsol tells me that rect 1 is an unknown variable.
How can I solve this problem?
Kind regards,
Sarah
