Beam resultants

Beam resultants are derived from element forces. Beam resultants are required for many beam post-processing operations, such as calculating complete stress results and displaying results on beam sections. To ensure that beam resultants are included in your results file, be sure to include a force output request in your solution.

Beam resultants are always displayed in the element (local) coordinate system. When displaying beam resultants, the Coordinate System option in the Result dialog box is disabled.

Mapping Pre/Post to Simcenter Nastran beam resultant components

The following figure illustrates the internal forces and moments for the CBEAM element:

The terminology used for beam resultants in the Post Processing Navigator does not match the terminology that the Simcenter Nastran in your .f06 file uses. The following table maps the internal forces and moments for the CBEAM element to the beam resultant terminology used in Pre/Post and the corresponding Simcenter Nastran convention:

CBEAM element forces and moments	Post-processing	Nastran .f06
Fx	Axial Force NXX	AXIAL FORCE
M1	Bending Moment MZZ*	BENDING MOMENTS PLANE 1*
M2	Bending Moment MYY*	BENDING MOMENTS PLANE 2*
Tx	Torsional Moment MXX	TOTAL TORQUE
V1	Shear force QXY	WEB SHEARS PLANE 1
V2	Shear force QXZ	WEB SHEARS PLANE 2
	Warping torque	WARPING TORQUE
Note: * For bending moments, the signs are reversed. That is, a negative value in Pre/Post is a positive value in the .f06 file, and vice versa.

For more information, see CBEAM in the Simcenter Nastran Quick Reference Guide and CBEAM Element in the Simcenter Nastran Element Library.
