Isn't there any possibility to apply the coupling constraint and the symmetry BC together, so I haven't to sum the reaction force at the nodes of the load area(99 nodes!).
I'm going to model several beams, so the summarizing of the reaction forces will take a lot of time.
I'm not putting the load on the model, but the deformation of the load area.
I'm using the coupling constraint because I want to know the reaction force(RF2) of the model. With the coupling constraint I can read this RF2 at the masternode.
I've modelled a three point bending test for a timber beam. I used the boundary condition XSYMM to model only the half of the beam and the constraint coupling to model the load (because the load will be divided over a surface). Because the two inputconditions contain several equal nodes Abaqus...
