I added internal edge elements which Elmer accepted without complaint. However I could not do an edge load in SMITC nor ShellSolver. elmer1.png I then made an internal row of elements a separate body so I could load only that row. elmer2.png Then ShellSolver calculated 4 point bend, you could approa...

To merge nodes, use the following command: Geometry.Tolerance = 1e-3; // adjust value here for correct merge result Coherence Mesh; By default, the nodes in the surface with lower surface/volume number will survive. If you want the opposite, you can either assign different numbers to them or apply t...

The attached xml was able to recreate the example and run to the correct solution without having to edit the sif.
Although the sif options were not the same as Mika's sif the resulting answer was the same.

The solution appears to have worked correctly with just Cartesian selected, however the manual says 7.4 Keywords Simulation Coordinate System String Cartesian 3D The coordinate system should be selected to be three-dimensional, although basis functions for computation correspond to 2-D finite elemen...

That would be fine with me. i would like to get the check boxes for large displacement and displace mesh working. I am reviewing the Elmer Models manual for the shell solver to see what other options are available. I will test the Cartesian.

case.sif built with shellsolver.xml. Calculate Stresses and Calculate Strains options did not work.Does shellsolver calculate stresses?

I started a shell solver xml for ElmerGUI. I was able to build most of the example, but still had to use the edit sif command to make minor changes. Some of the options I could add using the free text input. The large displacement and deform mesh check boxes didn't work in the solver general options...

ElmerGUI will only get you a small set of Elmer capability. You will have to learn ElmerGrid and ElmerSolver command lines.

You can set the initial temperature of all the bodies then specify the temperature at every coordinate by targeting coordinates or at every node by targeting nodes.
use the heatsolver for temperature and the elastic solver for strains

If you are reading the unv file into ElmerGUI there are known bugs. Using ElmerGrid to convert mesh to an Elmer mesh is a better experience. Also on this board is a Slaome python script to write an Elmer mesh directly from Salome.
