Contact Resistance
Posted: 20 Dec 2023, 17:14
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 = Current density (A/m2), h = specific contact conductivity (S/m2), and V1 V2 as the potentials in V.
I am referring to the following page:
https://doc.comsol.com/5.5/doc/com.coms ... 7.057.html
Is it maybe possible that the equations in the link can be used in the matrix stiffness matrix composition of the electrostatic poisson equation?
In case of two potentials,ie V1 and V2, that are located in the same node at the interface.
Would it be hard, would it even make sense?
Your thoughts about that are apreciated.
Cheers,
Domi
