Hello everybody

I am trying to solve a 2D axisymmetric problem of heat transfer corresponding to an annulus. I have all the four edges defined as walls, the left one with a constant heat flux, the right one with a constant temperature (=298 K), the top and bottom as insulated.

The problem is that once I run the solver and post process my results, I see that the tempeature on the right edge is not equal to 298K as it should be. It gives me something close, like 299K or 300K but not what I impose on it.

Please let me know as to why this is happening. What should I do to overcome this problem??

Thanks

the walls are adiabatic or no chankhar
