Samgopiraj, It's not clear to me that you even understand the physics behind what is happening to your block. Think about what is causing the deformation. Once you figure that out, read the ANSYS manual on how to model that physical behavior. The folks on this list will help you with specific ANSYS related questions, but only if you demonstrate that you know the engineering fundamentals.

The block when subjected to a repeated 2000 thermal cycles (ONE CYCLE - 1._at_Time 0, 24 degree C 2. _at_Time 10 min, Temp 700C, _at_Time 70, Temp 700C, 4. _at_Time 80, Temp 24C.)showed deformation at the edges. I am trying to simulate it in ANSYS... How do i do it? Regards, Samgopiraj Yadav, MS - Mechanical Engineering, Tennessee Technological University Cookeville.
