Yes and no.  Depending on the strain energy results, I will make partitions and add materials with higher modulus of elasticity (the region where the load is located included). I was just trying to know whether I can make that line rigid (not deform) and apply the load in the rigid line. Abaqus seems to have Analytical Rigid surface, so the load is applied to rigid surface, and is not depended in a node. 

The shift of the force from the vertex is not a problem at the moment.
