lin_vel_node_wrtA¶
- class sharpy.structure.utils.lagrangeconstraints.lin_vel_node_wrtA[source]¶
This constraint forces the linear velocity of a node to have a certain value with respect to the A FoR
See
LagrangeConstraints
for the description of variables- node_number¶
number of the “node” within its own body
- Type
int
- body_number¶
body number of the “node”
- Type
int
- vel¶
6 components of the desired velocity with respect to the A FoR
- Type
np.ndarray
