total_forces_momentsΒΆ
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
np.array
