Changing heat source in ANSYS
Dear Colleagues,
I have got a little problem which I hope you could help with. I would like to use heat source which is decreasing in time period (e.g. 18MW in 1 sec, 15 MW in 2 sec, etc.). It's decay heat from low-power nuclear reactor, geometry at this moment is not so important, I will just use simple geometry in 2D. Is it possible to solve this issue in ANSYS? Does anybody know how to do it? Thank you in advance for your help. |
Hello. I believe You can use "expression" as an input (I don't have time to confirm it right now). Here is an expression I was using for varying inlet temperature. I think You can modify in for Your purpose:
Code:
300[K] + if(t>6300[s],0[K],if(t>5400[s],600[K],if(t>4500[s],0[K],if(t>3600[s],600[K],if(t>2700[s],0[K],if(t>1800[s],600[K],if(t>900[s],0[K],600[K]))))) Best regards, Sheaker |
