A remote point in Explicit Dynamics consists of a:
Location - The point in space from which a remote boundary condition can be applied.
Scoped region - The area of geometry the remote point is scoped to. The nodes of this scoping form a group of rigid body nodes along with a further node created at the remote point location.
Boundary condition (optional) - The Remote Displacement and Remote Force boundary conditions are currently available as remote boundary conditions.
The Explicit Dynamics solver does not support Deformable Behavior when using remote points.
The group of rigid body nodes which is created is treated as a regular rigid body by the Explicit Dynamics solver. For example, if the scoped region of the remote point consists of two faces from two separate parts, the solver will determine the center of mass and the inertial properties for all the nodes, with all the nodes making up a combined group of rigid body nodes. This calculation creates a rigid connection between the two parts.
In the solution, the forces acting on the group of rigid body nodes are summed at each time step. This calculation determines the rigid body motion of the nodes belonging to the remote point. Due to the mandatory rigid behavior of Remote Points, the group of rigid body nodes are unable to deform, even if the elements of the parts used have flexible behavior. The group of rigid body nodes are, however, free to translate and rotate. Due to this restriction it is important to maintain a sufficient number of nodes in the scoped area of a remote point when scoped to a flexible solid part.
Note: When using Remote Points in Explicit Dynamics analyses:
The Behavior field must be set to Rigid. If it is set to Deformable the solution will terminate and an error will be generated.
Only the remote displacement and remote force boundary conditions are supported for Remote Points in Explicit Dynamics analyses.
Commands are not supported for Remote Points in Explicit Dynamics analyses.
Remote Points and boundary conditions are not supported for 2D Explicit Dynamics analyses.
Remote Points cannot be scoped to bodies with reference frame of type Particle.
