STEP file 2D question

[fbartra]

How is the "horse shoe" step 2D file example created?
are there any requirements about how the 2D step file is created?
i.e. I created a simple "square" sketch in solidworks (not a solid) and converted to step.
But Elmer can not load it

Please advise

Thank you

It is supplied with the installation

/usr/share/ElmerGUI/samples

or whereever ElmerGUI is installed

or on github

Thank your reply
But what i am looking is to make my own step files
I just need to know for 2D how do you design them? just a surface with "zero" thickness?

I tried the above but Elmer does not seem to recognize it.

Thank you again

Yes it would be a planer surface, what tool are you using to create the surface?

[fbartra]

I use solid works
so I am only define it as a "sketch"
may be this is the wrong way to implement it.

what tool would you suggest to try?

Sorry, it appears ElmerGUI will only open 3D model step file. The file in the horseshoe tutorial is a mesh file, it was created and meshed in gmsh. gmsh saved the file horsehoe.msh.

For 2D geometry ElmerGUI says to use another mesh generator, gmsh is a popular one. You can create geometry or import step files in gmsh, generate the mesh in gmsh, use the save mesh option.

you will get a .msh file that ElmerGUI will open.
