Posts: n/a
In my problem ,I just want to define a heatfunction and display it's contours after solving. My problem describe as: in a square the left side is define as hot wall and with a constant temperature,in the right side is cold wall ,the up and down side is adiabatic. The transport equation is H+d(TV)/dx-d(TU)/dy=0 . I just want to define it by udf ,but now my confusion was how to define heatfunction BC in udf?

Thanks all
