Re: SIGSEGV Fault in parallel, but not serial
Hi I changed the MPI communicator and the solver may now function better. Prior to this it did work in parallel but only if the Coil was active in all partitions. The mortar stuff would be much more difficult to implement fully parallel. The issue there is that all search algorithms should be parall...

Re: Point data in parallel runs
Hi I tried to fix this. At one point the saving of point data was made more generic (e.g. it can handle Hcurl elements at the node) but it may have broken this parallel operation which was not guarded by tests. Thanx for reporting. It is good idea to use the "exact" mode that find the elem...

Re: How to Start Using Particle Dynamics Solver
Hi Alberto, The velocity should be the velocity of the particles. If there is no electric field the particles will stay at rest (in this test). When I increase |B| from 1 to 2 the results change at least for me. Maybe you set the electric field to zero and particles never start. This is really the o...

Re: lagrangian element selection
Hi I don't think the "double usage" is anything special. This lies in the very heart of isoparametric elements. Here is one paper from 1968... https://www.sciencedirect.com/science/article/abs/pii/0020768368900310 Now there is a pragmatic reason not improve the geometry description using t...

Re: Temperature plotted in non activated body
Hi I would use "Threshold" filter in paraview to only activate the regions of interest. Or maybe even better use "vtu part collection". This creates separate file of each domain. If you give bodies (and BCs) nice names this is very informative. For more instructions see: http://w...

Re: How to Start Using Particle Dynamics Solver
Hi You could save the results and do a restart where you omit recomputation (deactivating the unnecessary solvers). You could fit a point cloud coming elsewhere etc. containing B field, for example. You should maybe define "splat". Generally there are models on what happens at boundaries. ...

Re: lagrangian element selection
Hi, Probably you cannot combine 1st and 2nd order Lagrange elements with the same mesh. Lagrange element always follows the number of nodes in the element. You can have different p-elements. E.g. "Element = p:2". This uses the lowest order Lagrange elements for the shape but the order of e...

Re: Electric dipole. Convergence problem.
Hi,
You should have both BCs at the same time.
VarName = Real ! nodal dofs (H0)
VarName {e} = Real ! refers to edge dofs (Hcurl)
VarName {f} = Real ! refers to face dofs (Hdiv)
So "AV" has both the scalar (H0) and vector (Hcurl) potential in the same field.

Re: Magnetostatic pair of coils
Checking at SOLVER.KEYWORDS this was introduced last May. We almost always use "devel" branch and the nightly builds are based on that too. -Peter
