Hello Elmer Community,
Can you please help me figure out why I can't replicate the "VectorHelmholtz Waveguide Bent problem"? In my case, I've kept it as a rectangular box (removed the bent part). I followed the tutorial, but I can't visualize the electric field/Poynting vector moving through the channel. I hope you can identify the error. Thank you for your help in advance. I've attached my input files for you to examine.
Kind Regards,
K. Batra

Re: Wave Propagation in Bent Waveguide - VectorHelmholtz
units of the constants are in SI units, so your box is 100 meters wide. Is that the intent?

Thanks for your answer. Here I attach the dimensions of my waveguide.

The .msh file does not know anything about units. Hence the information is lost in translation and you end up mm being interpreted as m. -Peter
Re: Wave Propagation in Bent Waveguide - VectorHelmholtz
Thanks Peter for pointing out. My intent is to have dimensions i.e. a= 10 cm and b= 5 cm.

The nodal values in the file are in the range of 100.
there is a coordinate scale option in the simulation section
coordinate scaling = 0.001
would put it in meters

Hello again,
Thanks for your answers. I really appreciate it. I was able to solve the problem with one box
Now I extend the problem and added two more boxes to create a channel. Unfortunately this time I can't visualize the electric field/Poynting vector moving further. I hope you can identify the error. Thank you for your help in advance. I've attached my updated input files for you to examine.
Kind Regards,

Re: Wave Propagation in Bent Waveguide - VectorHelmholtz
In your mesh you do not have 1 body you have three bodies. In your sif you only specify elmer body 1 as mesh body 1
I think your intent in the sif would be
Body 1
Target Bodies(3) = 1 2 3
Name = "Body 1"
Equation = 1
Material = 1
End
or merge the three bodies into 1 body in the meshing
I think your intent in the sif would be
Body 1
Target Bodies(3) = 1 2 3
Name = "Body 1"
Equation = 1
Material = 1
End
or merge the three bodies into 1 body in the meshing
