ElmerGrid -increase generates elementtype 0 and elmersolver then fails
Hi, I'd like to export a .unv mesh from Salome, to then convert it to Elmer format using ElmerGrid. The mesh contains HEXA8, TETRA4 and PYRA5. Salome cannot export PYRA5 elements to .unv mesh. So I exported the mesh from Salome to Elmer by using the following Python script: https://github.com/jvence...

Re: electrodynamic forces on busbars
Hi, Please bear with me, but I'd like to better understand the three steps: 1) Use AVSolver to solver for electric/magnetic fields Currents are non-sinusoidal time-varying waveforms which can be computed by other means (not by elmer): they depends on the caracteristics of the utility grid upstream t...

Re: electrodynamic forces on busbars
Hi kevinarden, from what I understand, the post you linked deals with the electric field. The forces between conductors are generated by the intercations between the currents and the magnetic filed generated by the currents themselves. The effect of the electric field is negligible. I believe the pr...

electrodynamic forces on busbars
Hi, in case of short-circuit inside or downstream an electrical cabinet (supplied from a low voltage 50/60 Hz grid), the electrodynamic forces amongst the conductors inside the cabinets can be relatively high. Here is an example of a paper that deals with this subject: https://www.studiecd.dk/cahier...

Re: "HeatSolveVec" "HeatSolver" simulation time speed up?
Hi, Thanks to both of you for your support. It appears to me that Save Coordinates crashes when it is used along with Discontinuous Galerkin. I have uploaded a simple example here: http://www.elmerfem.org/forum/viewtopic.php?t=7698 The problem is not caused by the keyword 'Real' I have to experiment...

Re: Save Coordinates Crashes with (Discontinuous Galerkin) Heat Gap
Hi Rich,
the purpose of the 'Discontinuous Galerkin' line is to implement a heat gap between the two bodies: If one replaces the line 'Discontinuous Galerkin' with 'Discontinuous Bodies' in solver 1, then the heat gap is ignored by the solver: Thanks,

Save Coordinates Crashes with (Discontinuous Galerkin) Heat Gap
Hello,
attached is a minimal example where 'Save Coordinates' crashes when the HeatGap between 2 bodies is active.
OS: Win 8.1

"HeatSolveVec" "HeatSolver" simulation time speed up?
Hello, given the mesh and given the computer (i7-9850H @ 2.6 GHz), does anyone have some hints to speed up a 3D Heat simulation? Are there any parameters in the Solver 1 section that can be modified to improve the simulation time? Here are the mesh information: mesh_information.png The simulation ti...
