Good to hear that you figured out the path issue. Take a look at the consistency tests located in github: https://github.com/ElmerCSC/elmerfem , under elmerfem/fem/tests. One example that includes an F90 user function is: elmerfem\fem\tests\RaviartThomas3D . Most of the menus in ElmerGUI include fre...

One possibility is that the path to Elmer is in the last position in the list of paths. Refer to Fig 4.2 in GetStartedElmer.pdf. Click on Path, then Edit, which should open the list of path entries. Select the path to Elmer/bin, and move it up to the top position. You may need to edit the environmen...

Sourceforge has old Elmer installers. It is recommended to use the latest Windows installers located here: https://www.nic.funet.fi/pub/sci/physics/elmer/bin/windows/ You may also want to follow the installation instructions in GetStartedElmer.pdf, located here: https://www.nic.funet.fi/pub/sci/phys...

For LInux, use *.so:

elmerf90 -o heat.so heat.f90

For Windows, use *.dll:

elmerf90 -o heat.dll heat.f90

This will generate the output file 'heat.dll', which should work. If this doesn't help, then something else is going on...

Hello,

Out of curiosity, just how did Elmer get named? There must be a story behind the name.

Hello,

Just a guess, maybe try commenting out the 'Physical' commands, and use the body and boundary numbers in the sif. Loading the mesh in ElmerGUI after commenting out the 'Physicals' gave two bodies and 12 boundaries.

Hello, To check for a conforming mesh, add this statement to the simulation section of a sif: Desired Mesh Pieces = 1 then running with your mesh, ElmerSolver reports an error and exits: CalculateMeshPieces: Number of separate pieces in mesh is 2 ERROR:: CalculateMeshPieces: Number of pieces differ ...

Hello,

Take a look at this forum thread:

Hello, Regarding this statement in your previous post: According to ElmerTutorials.pdf, section 17 (17. Helmholtz – 2D – Acoustic Waves – Air in a Cavity), they refer to pressure wave in the x-direction and y-direction. As written, the tutorial could be misleading. The tutorial probably should say s...

The attached archive includes bug.geo and four scripts. The scripts will run gmsh and output the msh file in both format 2 and format4, followed by ElmerGrid converting both msh files into elmer mesh format. ElmerGrid converts the gmsh format 2 msh file, retaining the duplicate boundaries. ElmerGrid...
