Hello,

I am wondering how to set an initial temperature to be a linear (in radius r) temperature profile from, say, T_A at r_a (inside wall) to T_b at r_b (outside wall) for, in this case, a cylindrical annulus.

As my boundary conditions, I have the inside and outside walls of the annulus two different temperatures, and I want my inside temperature to go from the one temperature to the other temperature linearly. Is there a utility that can do this or some way of coding this?

Thanks,
Trevor

Set p like T so fixed value on your annuli, zeroGradient on front and back.

Copy (by hand) resulting internal field of pressure back into T.
