I am trying to simulate a simplified version of a beam resting on 10 points using Abaqus. The solutions I want to obtain are the Reaction Forces in each resting point or area when applying a vertical force of 100kN. I have made several attempts following different methods but the RF obtained are alwais 0.
In the pictures below you can see the model and how I defined the boundary conditions. In the lower part of the beam, I defined 10 different areas, in which the beam rests. I also defined a Tie type MPC constraint to define the vertical displacement boundary condition (U2=0). In the result you can notice that the whole part has a value of 0 in the reaction force magnitude (RF).
What can I do to obtain these forces?
Dear Amaia Cendoya,
Maybe the next quotation from manual will be helpful: "MPC constraint forces are not available as output quantities. Therefore, to output the forces required to enforce the constraint specified in an MPC, you should use an equivalent connector element. Connector element force, moment, and kinematic output is readily available and is defined in Connector element library."
