Hi everyone, the computational time for calculating von Mises stres on material with transient temperature distribution is taking so long for me... Please can anyone tell me what wrong i have done?? Else please suggest how to reduce computational time....

Hi,
Difficult to tell without more information, but there is one thing you should think about:
The vast majority if thermal stress problems are one-way coupled, in the sense that the thermal problem is independent of the structural deformations. When this is the case, it is much more efficient to first solve the thermal transient separately, and then do stationary structural analysis using the computed temperatures.

Henrik
