Hi,

I am trying to cool glass (viscoelastic material model) from its transition temperature to a specific temperature near its annealing temperature by gradual cooling, by specifying the cooling rate. I want to estimate the residual stresses as a result.

I am not clear as to how to specify the problem in ANSYS. For ex, if I want to cool from 500 C (which is also my reference temperature) to 200 C at the rate of 2C/sec, then how do I specify the cooling rate and the end temperature in ANSYS?

I know how to specify the TB, PRONY and TB,SHIFT data etc., but I am able to understand how to specify the rate and the start and the end temperature

Any help/suggestions will be really insightful.
Thanks for your time.
