Elmer Discussion Forum

Hello fellow Elmers, i wanted to ask if you guys know how hard it would be to develop your own solver in the field of contact resistance. I basically would implement an infinitesimal small Area Resistance (Contact Resistance) by following equation. n * J = h (V1-V2) , where n = Normal Vector, J = Cu...

Okay thanks, that is very good to know.

Thank you for your reply!
This would eliminate the thermal resistance problem.

But is there also an option or flag for Electrical Contact Resistance?

Hello Community,

i wanted to ask if you know anything about the implementation of thermal and electrical contact resistances.
I couldnt derive it from the existing test .sif files, so thats why im asking.

Thanks for your answer, that makes sense!

Hello Rich, thanks for your answer! Now i get the abbreviations. Can you make sense of the values posted before? Like 480 0.3135E+01 490 0.3263E+01 500 0.3249E+01 501 0.3249E+01 This seems also like a time or iteration step measure for the convergence. But this deviates from the convergence that is ...

Hello fellow Simulators, i wanted to ask you what the numbers in my output mean. I am a little confused in decrypting what it means. Mostly what i dont understand is the variable "nrm". Also when you see in my log file the numbers that kind of repeat themselves. For example 10 0.7514E+00 e...
