Coupling DOFs of an edge (Degrees of Freedom)

Hi!!
I am working with a 2D model in the solid mechanics module, the idea is to keep a straight line straight after impossing a displacement in other edge of the figure. First I tried with "Rigid connector" boundary, but it induces big strains in my model. Therefore I was wondering if it is possible to couple all the degrees of freedom on the edge as it is done in ANSYS so the edge keeps straight with not that big strains and tensions caused by the rigid connector

Hi,
There are several ways you can do that. In the model
www.comsol.com/model/thermo-mechanical-analysis-of-a-surface-mounted-resistor-481
you can see one example where two boundaries (in 3D) are kept flat by setting a prescribed displacement over the whole boundary equal to the (yet unknown) value in a single point on the same boundary.
This model is also available in Application Libraries->Structural Mechanics Module->Thermal-Structure Interaction->surface_resistor

Henrik
