Elmer Discussion Forum

Hi Peter, I solved the libocct issue by simply cloning the elmer and compiling the code. However ElmerGUI core dumps: $ ElmerGUI realloc(): invalid pointer Aborted (core dumped) On Ubuntu 20.04 I have installed the Qt4 libs from the ppa:rock-core/qt4 repository as suggested by https://ubuntuhandbook...

Hi Peter,

thank you for prompt reply, will check ...

Hi, with the latest version of Kicad 7 is based on libocct and so packages are conflicting. Similar issue was between FreeCad and KiCad https://gitlab.com/kicad/code/kicad/-/issues/8783 Kicad 7 requirements: Depends: libc6 (>= 2.29), libcairo2 (>= 1.14.0), libcurl4 (>= 7.16.2), libfontconfig1 (>= 2....

Hi Rich, thank you for the nice example and also runs very fast ~32 seconds, non-parallel exec. gmsh generates around 200k elements. Had to "!Mask Name" to get calcs in the rectCore.dat file. This particular material from the article has the following params: PFM Dipoles Field Strength(1) ...

Hi Peter, thank you for the tip, the elemental fields do show correct results, however results only make sense with mean : Mask Name 1 = "Flux1" Variable 1 = Magnetic Flux Density e 1 Operator 1 = boundary int mean Variable 2 = Magnetic Flux Density e 2 Operator 2 = boundary int mean Varia...

Thank you for tips. Let's try the last image, with added skin to the core:
So the main Q is still why SaveData is showing zeros ...

Hi Rich, For the grid density am using it in the .opt file, that is/was attached besides the coreWire example. Going back to the "skin"; with the Coherence I get a nice "skin" looking at gmsh and loading back the msh file, also attached below, and also in the resulting paraview I...

Hi, Super. I am trying to get a better internal homogeneity in order to obtain better average calc of the core flux; so have added a "skin" layer to your original .geo. The result in paraview is good, but have problems with the SaveData; results are all zero, even though boundary condition...

Hi, It seems like the Flux Average does not work or needs additional treatment, but changing it to your example it works, so adding the Save Scalars: Boundary Condition 4 Name = "Core Flux 1" !Magnetic Flux Average = Logical True Save Scalars = Logical True End Boundary Condition 5 Name = ...

Hi Rich, based on your example, changed some naming to fit my .sif, did some flux measurement tests. Complete project is attached below, with 'make' (defaults to 16 CORES for fine mesh). Thing to explore is which per-conditioners would in this case improve the convergence speed. With BiCGStabL polyn...
