Hi All,
This is a thermal question but I think those who have experienced in APDL can help too. I want to define a boundary condition for a cylinder in a way that this boundary condition changes with time t and height z. Let's say this function is
T(t, z)=Ln(z*t)+z+t+20
How should I write a short APDL command block in workbench? I know that I should insert the command in the boundary condition but I do not know how to write the appropriate code. At least I need some examples so that I can learn how to do that.
Thank you
