Elmer Discussion Forum

Dear Rich, thank you for your reply. I checked the model manual, it is indeed possible to apply boundary current density (Neumann BC) to external boundaries of the model and the results seems fine for me. My question is how to deal with an internal boundary that is a current source, for example, the...

Dear all, I have a silly question here. I know that in Comsol, one could apply a terminal BC to an internal boundary and use it, for example, to dump current to a system in a electrostatic simulation. The terminal BC uses lumped parameters to ensure continuity at that interface. I would like to mode...

Hi all, I have been playing with Elmer for a while now and decided to run my on case. I would like to simulate microwave ablation on liver tissue, for biomedical applications. So, basically, as a first step, I would like to compute the damped electric field that a microwave antenna radiates into the...

Thanks everyone! That makes totally sense, I have played a bit with the mesh size and now I can get pretty close to the values on the tutorial.
Yeah! I knew it was something silly!!!

Thank you all again!!!

Sorry for bringing up this question again. I am still struggling to get the same results as in the tutorial.... :cry: I am sure it is a silly mistake that I cannot figure out. May someone please help me? I am currently using the BiCGStabl with vanka preconditioner to solve the Vector Helmholtz Equat...

Thanks!!!!

Dear all, I am trying to replicate the tutorial for vectorial helmholtz, but with no luck. I am sure that I am missing something along the way, but couldn't figure out what. Really appreciate any inputs. Attached is my .sif file and the log file. The Energy Functional value that I obtain is: -303734...
