Specifying initial condition as an expression/function in transient problems?

Please login with a confirmed email address before reporting spam

Hello,

I am solving a transient heat transfer problem in version 4.2 and would like to specify a spatially varying temperature distribution (i.e. T=F(x)) as the initial temperature of the domain . Could you tell me how can I achieve this?

Thank you.

Hi

well exactly as you wrote it, use "x" or "X" depending on your model, check which is referring to the original Reference frame, i.e. "X" if with solid physics included

Most GUI window entry lines are for equations, you should read it per X,Y,Z, or rather what is applying to a small element dx*dy*dz

Good luck
