Hi,

I have using a step function in a time depenedent study where I want to increase my voltage from 0 to 75V in 4 ms. For this I have given voltage by this function Voltage*step2(t[1/s]). Here my input paramter Voltage is defined as 75V.

If I understand the attached graph correctly- it means at 0.003s , the voltage will be (75*0.85 = 63.75)V Is it correct interpretation?

Hello Shrutika,

Yes, from your plot it looks like step2(0.003) will return about .85. If you want to know the exact value, you can have COMSOL compute step2(0.003) via a parameter.

Best,

Jeff
