total_forces_moments

Performs a summation of the forces and moments expressed at the structural nodes in the A frame of reference.

Note

If you need to transform forces and moments at the nodes from B to A, use the nodal_b_for_2_a_for() function.

param forces_nodes_a:

n_node x 6 vector of forces and moments at the nodes in A

type forces_nodes_a:

np.array

param pos_def:

n_node x 3 vector of nodal positions in A

type pos_def:

np.array

param ref_pos:

Location in A about which to compute moments. Defaults to [0, 0, 0]

type ref_pos:

np.array (optional)

returns:

Vector of length 6 containing the total forces and moments expressed in A at the desired location.

rtype:
