Re: Electric Field at Dielectric Interfaces

You could have a discontinuous boundary where the bodies do not share nodes. Then you can use mortar conditions to enforce sharing data across the boundaries, and then each boundary for each body can have its own condition. Elmer even automates some of this with discontinuous boundary = true.

Re: Gmsh: extrusion help

If you extrude the surface elements into solids you probably do not get a surface boundary on the solids. EmerGUI displays solid bodies by its boundary elements so in this case nothing will be visible. To turn on solid elements use view and che k on the solid element option

Re: Plastic Deformation possible?

Calculix has much more in plastic deformation capability and it also has fluid flow. Elmer is better at fluid flow and coupling but it's plastic deformation is limited There has been some user subroutine work on plastic deformation

Re: How to use measuring tools

I use ElmerGrid to convert it to a vtu and import it into Parkview. In Parkview you can use many tools but one is hover point on allowing you to see the nodal data by just hovering the mouse pointer over a node

Re: WhitneyAV / Solution trivially zero!

I do not have that problem. Using your mesh coil_test.msh and your sif coil_test_simplified.sif
I get a solution coil current = to 1, which is the default

Re: Acoustic waves propagation in a solid body

I agree with Peter that ultrasonic is doable. There are basic wave problems in the test cases
