reaction force

Hi,

What is the difference between the nodal force (NFORC) and Reaction force in abaqus. I applied some displacement in my model, when checking the Reaction and Nodal force at the same node, Nodal force is just half the reaction force. Then I did some experiment and applied some load on a node, after solution when i check the nodal force on the same node, it is half of the applied load. Why is it not  same as the load I applied? I am confused. Please help me.

 Thanks,

Dear all,

This is my first post in iMechanica forum.

I am trying to some simulation of cantilever beam bending in abaqus. Since the aspect ratio is pretty low (height/diameter~=2), I use 3D solid element instead of 2D beam element to construct the beam. I set the deflection at the free-end as the boundary condition, and try to solve the reaction force (perpendicular to the beam longitudinal axis). But I get in trouble to calculate the total reaction force at the free-end.
