Hi Sebastien,

Thanks for your reply,
I apply the heat source starting from the point (x0,y0,z0) so the laser beam is on face 11 and moves in the x direction which is the refined face.

This is working now, I changed the function for the heat source such that the spot size depends on z.

Hi, I am trying to model keyhole mode laser welding but for some reason there only seems to be a pulse at the middle of the weld path and then the heat dissaptes soon after. This worked for a normal volumetric heat source but when I try to add anything that would make it resemble the heat disributio...

Hi thanks for your answer,
but how does equating the Electric robin coefficient yeild the primary and scattered fields to be waveguide modes?

Does anyone know why it is like this? Any information will be helpful as I am still confused!

I thought any difference in the number was indication of a problem but since you have confirmed that it is ok I guess it's not a problem any more - Thank you for your help!

Thanks for your suggestion, I tried the following nigtly build: elmerfem-nightly_Windows-AMD64.zip
but it still doesn't match the output given by the Linux version and is the same as the old windows version.
I have attached the output and the data file produced by the new nightly build.

Hi, I am working through the tutorial of the bent waveguide that uses the VectorHelholtz solver and am a little confused by the boundary condition values given to the boundaries, Why is the Electric Robin Coeffcient im for the output equal to $beta0? Because isn't the outport suppose to be assigned ...

Hey, this is what I did but I'm no 100% sure it is right, so if anyone sees a mistake please correct me. For the wall I applied the Leontovich impedance boundary condition because since beta is complex it meants that the signal attentuates so the electric feild can't be zero. I followed what was in ...
