Performs a summation of the forces and moments expressed at the structural nodes in the A frame of reference.
If you need to transform forces and moments at the nodes from B to A, use the
- param forces_nodes_a
n_node x 6vector of forces and moments at the nodes in A
- type forces_nodes_a
- param pos_def
n_node x 3vector of nodal positions in A
- type pos_def
- param ref_pos
Location in A about which to compute moments. Defaults to
[0, 0, 0]
- type ref_pos
Vector of length 6 containing the total forces and moments expressed in A at the desired location.
