Thermal Strain simulations provide the highest degree of accuracy by predicting how thermal cycling affects strain accumulation at each location within a part. It uses inherent strain but also implements a thermal ratcheting algorithm to locally modify the inherent strain value.
In addition to the standard inputs as described in Set Up a Simulation - Assumed Strain, you will need to:
Consider using a Mesh Resolution Factor, a scaling factor to control speed versus accuracy of the simulation
Select an Ansys predefined, thermally validated material
Define additional configuration parameters of your 3D printing machine
