Re: Elmergrid precision

The unv format works fine. The issue here is the save all elements option. Gmsh by default only saves the grouped elements. If you want them all you either have to get them all into some group or use save all elements. Or there may be cases where you don't want all of the elements.

Re: How to apply "pre strain" in stresssolver

Try Pre Strain = Real 0.01. Some variables have to be declared in Elmer

Re: Checking if my geometry is correct

To unit the edges in gmsh use the coherence command.

Re: Checking if my geometry is correct

In which tool are you generating the mesh?

Re: ElmerGUI BC's and Forces

I don't think Elmer has truss elements, but if you make the inertia really small and only use point constraints and loads it will be truss like. To make it a frame just put in real inertia.

This type of modeling and solving is doable in Elmer, but CalculiX is more focused on this area.

Re: Sign of Lorentz force

Yes it is possible.

here is a test case example

/home/titan/elmer/elmerfem/fem/tests/NaturalConvectionRestart

Restart Position = 0

means restart from the last saved step.

You can also control how many steps are saved.
