Hello, I wrap the steel bar in the figure with a coil and simulate it in Ansys Maxwell. Then, I want to transfer it to Ansys Fluent and see how long it has heated up in transient analysis. However, even after a long period of time, only a few degrees of temperature increase is achieved. I think the reason for this is because only joule heating is used in Maxwell. I think that if I can perform induction heating, I can achieve a high temperature increase in a very short time, as in reality. I am waiting for your suggestions on how I can do induction heating with Ansys. Thanks.

Hello Unda,

Induction heating can be simulated in two ways.

• By carrying out an analysis in Maxwell with peak current pumped into the model and trasnfering the steady state results to thermal for hte computation of the temperature.
• Use system coupling option which would help you to do data transfer between for the electromagnetic solver and thermal at defined intervals of time to take care of the thermal effect on the losses.
