Hello,

I'm writing a code to calculate two different fluxes with different heat coefficients, but it seems that in Materials, ElmerSolver does not read the Heat Coefficients, which names are Heat Coefficiente_n and Heat Coefficient_p. The message is:

"ERROR:: Model Input: Unknown specifier: [name]

ERROR:: Model Input: In section: [material 1]

ERROR:: Model Input: For property name:[material 2] "

¿What could it be the mistake?

The solvers and Material codes are:

Solver 4

Exec Solver = After Simulation

Equation = "flux compute_Jp"

Procedure = "FluxSolver" "FluxSolver"

Flux Variable = String "Temperature_p"

Flux Coefficient = String "Heat Conductivity_p"

! Discontinuous Galerkin = Logical True

Calculate Flux = Logical True

Calculate Grad = Logical True

Linear System Solver = "Iterative"

Linear System Iterative Method = "BiCGStab"

Linear System Preconditioning = None

Linear System Max Iterations = Integer 100

Linear System Convergence Tolerance = 1.0e-10

End

Solver 6 ! calculate the heat fluxes in the bodies

Exec Solver = After Simulation

Equation = "flux compute_Jn"

Procedure = "FluxSolver" "FluxSolver"

Flux Variable = String "Temperature_n"

Flux Coefficient = String "Heat Conductivity_n"

! Discontinuous Galerkin = Logical True

Calculate Flux = Logical True

Calculate Grad = Logical True

Linear System Solver = "Iterative"

Linear System Iterative Method = "BiCGStab"

Linear System Preconditioning = None

Linear System Max Iterations = Integer 100

Linear System Convergence Tolerance = 1.0e-10

End

Material 1

Name = "Material_semic_p"

Relative Permittivity = 11.68

Heat Conductivity_n = Real $ Dn_q

Heat Conductivity_p = Real $ Dp_q

Heat Capacity = 0.0

Density = 1.0

Viscosity = 0.0

Electric Conductivity_f = Real $ sigma_p

Thanks in advance and looking forward to an answer,

John.

### Re: multiple fluxsolver

Any chance that there is a missing "End" statement in the sif file (before "Material 2" section starts)?
