Re: Flux in Axisymmetric
Yes, multiply by 2PI. The weak form of the PDE does not include the factor. -Peter

Re: adding youngs modulus as a function of stress
Hi
You should set "Calculate Stresses = True" and then you can make the Youngs Modulus depend on the results. Note that stresses are computed after the solver so you need to iterate on the coupled system level.

Re: von karman instability
Hi
Do you have same timestep size? The case is critical to the timestep. With longer steps the instability vanishes.

Re: simple adaptive meshing and MATC parameters, 2D steady state
Hi The VTU output problem is now fixed. There was a problem in that when we changed to case sensitive keyword (File vs. String) the matching of "Mesh Name" broke down. It would have workd with lowercase values only... Now fixed in devel. To my understanding there is only the problem of MATC & ElmerG...

Re: Element 'flipping' in a large displacement problem
Hi
Did you use the "ElasticSolve" capable for large displacements? If you did, was nonlinear system convergence obtained?
You might apply the load gradually with such large displacements.

Re: Problem calculating the magnetic energy of two coils
Hi Marco, I don't blame you for the confusion - it is actually the other way around. Usually source terms and body forces and boundary conditions in Elmer are distributed. I.e. the unit of "Current Density" is A/m^2. The idea is that we should not need any geometric information to interpret a keywor...

Re: Problem calculating the magnetic energy of two coils
Hi,
This is a follow-up to this thread that utilizes the CoilSolver to set currents in closed coils. Does not work always, but some observations are still valid also for this case.

Defining coils currents / five coils example
Hi All, There are multiple ways in Elmer to define coil currents in hierarchical simulations for the Whitney AV solver to compute magnetic fields. Basically one can give "Current Density i", i=1,2,3 or "Electric Potential" which is used to internally compute the current sources in the AV solver. Now...

Re: elmergrid regressions
Hi I looked at some of the errors. For example, there was new check for very long lines and this failed if the line ended not to end-of-line (\n) but to end-of-file (\0). This has now been fixed. Basically I don't think there is any other real problem than the missing of MATC which occured when Elme...
