Hi

Look at test case mgdyn_airgap_force:
https://github.com/ElmerCSC/elmerfem/tr ... rgap_force

There a concept of "component" is used to group together bodies. In these bodies you can automatically sum up the nodal forces that you have already computed.

Hi Mark

Are you sure that your heat is not convected away at the outlet, or is not eaten up to warm the system in a transient case?

Peter

Hi Basically the calc fields can compute nodal magnetic forces that are in units of Force i.e. Newtons in SI units. To have the total force you need to sum up the nodal forces in given domain. For this you can use the component concept. The force always has three components corresponding to each coo...

Hi

There seems to be two ways to account for friction: explicit and implicit. Look at test cases ContactFriction* for examples. The limitation is that frictional force is assumed to be proportional to the normal force.

Hi The problem is somewhat puzzling. The test case runs through for me, as well as on travis, see https://travis-ci.org/ElmerCSC/elmerfem/builds/512435283?utm_source=github_status&utm_medium=notification (only slow tests are skipped) You could perhaps try to remove the "CONTIG" parameter in reluctiv...

Hi julilo

This is still relevant:

Do you have any idea whether your system can be solved weakly coupled or as a monolithic system?

Hi Kevin, Nice work! We'll hopefully have time to review it and at to the distribution. Would this be ok to you? The "Cartesian 3D" is redundant usually as the code determines the mesh dimension from the coordinates & element dimensions. Hence you can usually use "Cartesian" both in 2D and 3D. -Peter

Hi joni I would perhaps not save everything in one file. Currently SaveLine does not support adding any index in a nice way. SaveScalars has the keyword "Line Marker" which makes it possible to mark different lines easily. Instead if you're running over several meshes you could have some simple unix...

Hi, Yes, the serious use of Elmer tends to be more about rather static workflows where the power comes from scripting, not from clicking. One could basically take any model in Elmer Models Manual and create an XML file for them to be usable via the GUI. Even the FredCAD and Salome Elmer plugin proje...

Hi Mark Ok, have to look into this someday. Seems strange. If the Name keyword is there then the ValueList_t associated with the boundary is not even empty. Btw, there is no need to define natural BC (heat flux = 0) since it happens when you do nothing. It may of course be helpful for people reading...
