Sir/Mam
I would like to give a rectangular wave temperature boundary condtion to the inner surface of an annular geometry. The maximum wave temperature is 663.15K and the minimum is 623.15K. Each temperature exists for about 3600s. The whole simulation is for 10800s.
I tried interpolation (in function - > Definition), but the temperature shift is not exactly at 3200s, 7200s as it should be since periodic. It happens near to it.
My table goes like 0s 663.15K, 3600s 663.15K, 3601s 623.15K, 7200s 623.15K, ... so on
I do not know how to use rectangle, step function though they seems to be more appropriate.
Kindly guide me. I shall be thankful to you for this. Harshal
