Hi,
i try to simulate a 3D model with a rigid coil over a moving metal-part. The simulation consists of three physics: moving mesh (ale), magnetic and electric fields (mef) and heat transfer (ht).
I implemented all three studies and particularly they work fine, but the problem is that the electromagnetic heat source moves with the partboundary and does not remain under the coil.
I have three single studies:
1. time-dependent: ale
2. time-dependent: mef
3. time-dependent: ht
So can anybody tell me where is my mistake?
Thank you
Robert

Hallo,
you should check the coordinate frames, Comsol has material frame (with capital XYZ) and space frame (small xyz). Although the part moves you should use transfer the heat density from emf to ht in the material frame.
In ht/Heat Source do you see a frame selection? Choose material?
I hope that does the trick.
