Load: Nodal Mass

Function

Enter lumped mass data (Lumped Translation Mass/Rotational Mass Moment of Inertia) for nodes, or modify or delete previously entered nodal masses.

Call

Model > Load > Nodal Mass

<Nodal Mass dialog box>

Load Set

Select a Load Set in which the specified load is included
Click to the right to prompt the Define Load Set dialog box to add, modify or delete the Load Set. If the user types the name of the Load Set directly in the entry box, GTS will automatically create the relevant Load Set.
 

Object

Type

Select a method of selecting a part where the loads will be assigned.
 

Curve

Select Curves on which the loads will be applied.

Surface

Select Surfaces on which the loads will be applied.

Node

Select the nodes directly.

Free Face Node

Select the nodes of free face of the selected element. All nodes within the defined angle (Feature Angle) from a seed node will be assigned.
 

Free Face Node

It becomes active when the Free Face Node selection method is designated.
 

Seed Node

Select a Seed Node which becomes the reference for determining the free face.

Feature Angle

When the free face selection is expanded from the Seed Node, it only selects element nodes within the specified Feature Angle.
 

Click to select the free face nodes, and they will appear on the screen.
 

Mode

Add

Add new loads to the selected nodes

Replace

Replace the previously defined loads on selected nodes

Delete

Delete the previously defined loads on selected nodes

Apply to Unassigned Objects Only

When adding new loads, this option applies loads only to the unassigned nodes.
 

Nodal Mass

Enter lumped mass data with respect to GCS.
 

mX

Translational Lumped Mass in the GCS X-direction.

mY

Translational Lumped Mass in the GCS Y-direction.

mZ

Translational Lumped Mass in the GCS Z-direction.

rmX

Rotational Mass Moment of Inertia about the GCS X-axis.

rmY

Rotational Mass Moment of Inertia about the GCS Y-axis.

rmZ

Rotational Mass Moment of Inertia about the GCS Z-axis.
