I have a problem when make a simulation of laser bending process

Hi

Can you please provide much more details on what you mean with laser bending, and what you would like to simulate. The more info provided the more feedback forum members can give.

All the best

Erik

The laser bending process means using laser power to deform sheet metal. To make the simulation, first add a moving heat source to the temperature distribution model, then use this temperature model as a force to bend sheet metal. when started to solve the transient thermal model, massage appears (unknown problem occurs) despite already meeting all requirement

Hi - that is good.

I believe in theory we should be able to predict this.

Can you post some images of your set up in Mechanical (say for the heat source/moving flux or)?

ALso see if there are any messages/errors in the SOlver Output in the Solution Information.

All the best

Hi

You are using the act extension which should work in principle.

I would suggest to use the transient thermal and use the moving heat flux, and not energy (that worked for me).

Also look through a tutorial to make sure it is set up ok.

 Actually, I used transient thermal and the moving heat flux before, the same unknown error occurs

I think the problem about temperature
