I an working on Joule Heating and would like to generate 3 repeated voltage pulse
Pulse Width: 100e-9
Rise and fall: 10e-9
This is what I tried
Lower Limit: 0
Upper Limit: 100e-9
Size of transition: 10e-9
Parameters >> Expression: rect1(mod(t,150e-9)
Plot Parameters>> Argument:t, Lower limit: 0, Upper Limit:0.001*
*With these setting, I can see the periodic waveform
Calling An1 in Electric Potential>>
Study >> Time: range(0,1e-9,4.5e-7)
Time stepping: Intermediate
Trying to see the temperature profile but it seems that the temperature keep rising up till 4.5e-. However, I do expect temperature to drop after each pulse interval before the next pulse starts.
What should I correct?
Please help. Thank you.
