How to extract Forces and Moment from Solid Tet Mesh Model?

I have one solid Y-strucutre model which i have modelled as assuming beam model in NASTRAN. From NASTRAN i am extracting internal loads (Nodal forces and Nodal Moments) successfully and then i am doing the strength analysis of perticule section by using internal loads. Now i have model the same structure using 3D solid finite element model by assuming Tet Mesh under ABAQUS. Analysis was running perfectly in ABAQUS. Now my problem is how to extract the internal loads from the 3D solid Tet mesh model for the same section. I need help to extract the internal loads from the solid Tet mesh. Please help me i am right now stuck at this point.
