Weird problem in Mechanical APDL. Please give ur comments
 

Hi.
I am doing a simple heat transfer simulation in ANSYS Mechanical APDL.

Normally under 'General postproc' there is "plot results" [under that "contour plot" and then "nodal solution"]

But when i simulate my problem, which is a simple steady state heat transfer between two rectangles one inside the other, THE "plot results" just vanishes.

Can any1 please tell me what could be wrong?
I can give further explanation/ or diagrams if it is not very clear..
