Showing a mid-plane cut with a plot along the length.

If you run the test case

but try second order elements with
ElmerGrid 1 2 tube.grd -increase

than the same error appears.

Elmer Stress Solver plus Helmholtz Scanning for resonance

I used basic formula firstmode.png Which gives 81.60 Hz for this model in vacuum. Ix = (bh^3)/12 = 8.333E-5 , E=200E9, L = 1, rho 7850, mass of beam = 0.1*7850 = 785 and from a text book the add mass for water at 1000 kg/m^2 for a rectangular beam cross section, the 1 meter depth in and out of the 2...

This solver tries to provide numerical means for setting the coil current. The idea is that the computed current density (or potential) may then be used in further simulations of magnetic fields. Now the natural way to create the currents is to solve a static current conduction equation. Unfortunate...

No I used the case_2.5d.sif.

If I use case.sif I get the same error, I do not know why.

I do not know what the extra BCs are in the 3d, they do not appear to be used.

Can you post the geo file

You may want to read through this thread, it has some similarities.

If you are putting an object in the cube, then I think it would work.

I just ran the 2d and did not get any errors. I also did not get these warnings WARNING:: ListFind: WARNING:: ListFind: Requested property: [Equation], not found WARNING:: ListFind: WARNING:: ListFind: WARNING:: ListFind: Requested property: [Equation], not found WARNING:: ListFind: Did you edit the...
