Re: Elmer version 8.1. is out

It is very interesting to hear about the contact modelling. That would make Elmer closer to be a substitute for commercial FE-solvers in the industry such as Ansys, Nastran and Abaqus. I've been working with industrial FEM now for a couple of years, and perhaps 95 % of the projects could then be sol...

Re: Rigid Body Elements in Elmer?

I guess that what I really want to do is to add some terms to the global stiffness matrix.

Will that work if I use different solvers, or do I have to modify the ElasticSolver to read my special 1d elements?

Rigid Body Elements in Elmer?

I would like to run linear elastic models in Elmer mixing 3d elements and 1d elements in form of rigid beams. I have multiple bodies and couple them with rigid beams simulating bolt joints. In commercial software like Nastran, there is RBE2 and RBE3, where all nodes belonging to the element have dir...
