### Re: Derivation magnetic co-energy

As further information, is this a simulation done in the frequency domain?

### Re: thermal expansion

The sif files repeats the constraint Displacement 3 = 0 twice in the same BC section. You should at least add constraints which prevent both rigid body translations in the X-Y plane and rotations around the Z-axis to have a unique solution. The lack of uniqueness may cause convergence problems. In a...

### Re: Definition of Concentration Diffusivity

It seems that the advection-diffusion solver reads the diffusion coefficient from the keyword command in the form my_solver_variable Diffusivity = Real ... where the part "my_solver_variable" should be the string which is used as the value of the solver variable. That is, the command Conce...

### Re: ShellSolver calculation of stress strain

Calculate Stresses = True Calculate Strains = True These commands work in the case of 3-D models, but strain/stress computation has not yet been implemented into the solver module ShellSolver. The old facet shell solver module FacetShellSolve (which is undocumented and whose use in shell analysis m...

### Re: Problem with transient heat transfer

Do you maybe have some further ideas to better physically introduce the flux in FEM methods that I could try out? If not, do you then suggest to check out finite volumes for these types of problems? I believe the mixed FEM formulation presented in the section "Mixed Approximation of the Poisso...

### Re: Modelpde with no stabilization

In Elmer the basic element definition for using the p-version of FEM is just "p:k", where k defines the order of approximation. Elmer then assigns automatically the right numbers of DOFs associated with different geometric entities (edges, faces and element interiors). Mixing the definitio...

### Re: Modelpde with no stabilization

It should be possible to apply bubble augmentation by giving a p-element definition. For example

Element = "p:1 b:1"

creates one elementwise bubble function. This construct doesn't depend on the keyword Bubbles and needs the background mesh consisting of the lowest-order elements.

### Re: GOLF rheology in ParStokes Solver?

I committed changes which should be quite close to what are needed here, see https://github.com/ElmerCSC/elmerfem/commit/8b78545b963eae289b74320b9fc91bb298d39eba and a small fix https://github.com/ElmerCSC/elmerfem/commit/9a9a5e3537b14a7546b7dd2f99a1d4678d1e4c05 I followed the convention that the st...

### Re: GOLF rheology in ParStokes Solver?

I think the book mentioned in the paper doesn't really treat anisotropy. If you can create a code which enables to represent the material law as T + p I = C^{ijkl}D_{kl}, with the righ-hand side expressed by using the Voigt notation (that is, the tensor C is then expected to be a (6x6)-matrix), I co...
