Hi, I am very new to Elmer and I am trying to simulate a heat transfer process on a brick wall with conduction, convection, and radiation. However, this error appeared on the Solver Log (attached below).
What should I do? I tried searching this error on the Forum's search bar and as far as I know there are no forum with this error return.
Any help is appreciated. Thank you very much

Re: There are no Solvers in the System
need to post your sif file and if possible your mesh

Dear Kevin,
Here is my .sif file.
What keywords should I use to find said solutions? Thank you very much

Re: There are no Solvers in the System
Hello,
In section "Equation 1", there is no solver indicated!
You should have a line of that type in this section
Active Solvers (1)= 1
But also you should have at least one solver section which tells which equation you are solving!
See examples in /elmerfem/fem/tests of the source code.
Regards,
Olivier

Re: There are no Solvers in the System
If you are building the sif with ElmerGUI you need to check the active solver box when you create an equation.
