Elmer Discussion Forum

Hi If you have the names present it may be convient to use them in your sif file rather than require ElmerGUI to do the numbering. See http://www.elmerfem.org/forum/viewtopic.php?t=4106 -Peter Hello Mr.Peter, Thank you for the additional input. So here is my understanding as of now: 1) I can set th...

OK! by setting the Parent 2 parameter to 0 for plunger and coil boundaries in the Boundary file I am able to select the various bodies separately! THANK YOU!. Now I can move on to generating current in a closed loop in the coil using coilSolver.

Hi Yes, the internal boundary without a BC is not used for anything in ElmerSolver. ElmerGUI seems to use it to highlight objects. That's certainly a deficiency. What is your original mesh format? Do you have "mesh.names" in your mesh directory? -Peter I have it in various formats right n...

Hi Internal boundaries are not needed to ensure continuity. They could be used to apply some additional flux but my imagination fails me to suggest what that could be in this case. Still, sometimes they can be useful for postprocessing. In this case maybe not so much because the postprocessed eleme...

No deleting the surface mesh and keeping only the volume mesh dosnt work.....i.e mesh will load but have the same problem of not being able to select the bodies individually

"Does setting the Parent 2 to 0 break the connections between Parent 1 and Parent 2...that is will the magnetic field generated by the coil still be able to permiate the air domain? I am asking because not the coil boundary is not having any connection to parent 2 by making it 0?" Elmer s...

Hi 1) Internal boundary may have two parents 2) When reading in the boundaries their parent information is verified 3) I guess in this case the internal BC is not even used to anything 4) ElmerGUI is more picky than ElmerSolver. I don't really have much experience on internal BCs on it. -Peter Ok. ...

I looked at the actual mesh files and the problem is that boundary 3 is associated with both the solenoid and the surrounding air Boundary 2 is associated with both the coil and the surrounding air. In Elmer a boundary can be associated with two bodies. I manually edited the boundary file to associ...
