I want to estimate the residual stresses as a result.</p> <p>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?</p> <p>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</p> <p>Any help/suggestions will be really insightful.<br /> Thanks for your time.</p> <p>Shriram<br /> --<br /> Research Assistant<br /> Structural and Multidisciplinary Optimization Lab.<br /> University of Florida </p>
