Thank you so much for the detailed explanations.
So, I like to model a thermal cycling condition where my PCB will heat -> cooldown -> reheat again. In reality, deformation after three cycles would be different from after just one cycle of heating and cooling. In ANSYS Static Structural, I added the following temperature points to my thermal condition.

The problem I am trying to solve with the ekill and ealive commands is this - the deformation after cooling down is the same as when it was heating up.

Here's how I deployed the commands which supposedly should deactivate all the elements and reactivate them (& reactivated elements should have zero strains) before proceeding to solve the next step. But, I still get the same values for deformation. The entire thing would solve without running into any errors, so not sure if it is even executed. Thanks
