  Hello Everyone,
  I am getting an error that the solution failed to solve completely at all time points, partial results at some at some points have been solved. I am trying to simulate Laser Transmission weld wherein I have used a Moving Heat Energy extension. I am using the 2020R2 student version of Ansys.
  Kindly help me.
  Thanks and Regards

  Convergence difficulties can be caused because of many reasons. In order to diagnose the problem please provide more information regarding the model setup along with images of the loading, BC's and solution at the last converged step.

  Hi Ishan Thanks for your response.
  I am trying to simulate laser transmission welding for PC and ABS. I have selected the top body as PC and the bottom as ABS. I have applied a constant pressure of 4.5MPa as shown below and a fixed support on all the side faces. I want the top body(PC) to be transparent, although I am not sure if I have selected so.
  After this to simulate the movement of the laser I have used a moving heat flux. I have added a fluid solid interface at the weld interface.
  I hope this helps. Please let me know if there would be anything else to be shared.
  Thanks and Regards
