a Kernel for del(V) * del(a function of T) #24245

Dear Moose experts, Hello.
So, there are two variables V(voltage), and T(temperature). Maybe, I can use the HeatConductionTimeDerivative, HeatConduction, JouleHeatingSource, and MatDiffusion kernels to solve the equation. In addition, if I have wrong thinking or derivative formula, please feel free to tell me. For your information, another equation is -sigma*del^2(V)=0; a current continuity equation that has no time derivative. |

Hello This last term does not look familiar so I m going to venture that we do not have a premade version. Making kernels should not be difficult if you followed the tutorial. An option btw, is to use an integration by parts on that term that will avoid requiring to take the derivative of that term. Guillaume |

There's also plenty of examples.
An option btw, is to use an integration by parts on that term that will avoid requiring to take the derivative of that term.
Instead you would have J Pi grad_test for the residual
