The only way I could get it to make a difference was
Body Force 1
Name = "Divergence Damping"
Pressure = Variable Coordinate 1, Coordinate 2
Real MATC "20e-6 * 10^((20 * log(sqrt(tx(0)^2 + tx(1)^2))/log(10) + 11) / 20)"
End

Re: Variable boundary conditon
Boundary Condition 1 Target Boundaries(3) = 1 2 3 Variable Potential Real Procedure "timestep" "timestep" End doesn't do anything so the module never gets called it should be something like Boundary Condition 1 Target Boundaries(3) = 1 2 3 Potential = Variable Time Real Procedure...

Re: H-B curve data input error
No it needs to be in the working directory with the sif and mesh files.

Re: H-B curve data input error
I would use the free text input field. You can either put the whole material in the text file or just the curve.

Re: WhitneyAVHarmonicSolver - "unphysical" solution
I use salome, and in this case I mesh the end with quads and extrude it into solids. If you create groups of the quads, they extrude into the different bodies.

Re: Can't I use a 2nd order mesh with the acoustic solver?
If you run the test case
https://github.com/ElmerCSC/elmerfem/tr ... HarmonicNS
but try second order elements with
ElmerGrid 1 2 tube.grd -increase
than the same error appears.
