Admas Panel

Use the Admas panel to create and update masses applied to nodes. The Adams panel supports the /ADMAS Radioss and *ELEMENT_MASS LS-DYNA element.

Location: 1D page
Important: Only available in the Radioss and LS-DYNA solver interface.

Create Subpanel

Use the Create subpanel to define a mass for entities (nodes, node sets, components, and component sets), which can be selected by selecting nodes, components, properties, materials, sets and blocks from the model.
All of the selection options (nodes, components, properties, materials, sets and blocks) are available. However, when selecting groups of entities, only entities of the same type can be selected. Regardless of type, a node set is always created from the selected entity, and the defined mass is always applied to this node set.
You can only select nodes, components, or sets. The corresponding *ELEMENT_MASS is created, depending on the entity type selected. You can select more than one node or component, but the selected entities must all be of the same type.
Option Action
attach node as a set Place the selected entity in a set and define the mass for the entire set.

Radioss: This checkbox is always selected because this option is required by the solver.

LS-DYNA: When this checkbox is enabled, each selected entity is placed in a node/part set, and the mass value is associated with the set. Clearing this checkbox keeps the selected entities separate/ungrouped.

mass= Define the mass to be applied on the selected entities. How it is applied depends on mass type.
mass type Radioss:
Individual mass (type 0)
Add the mass value to each of the nodes in the set.
Distributed mass (type 1)
Divide the mass value evenly among all of the nodes in the set.
Added mass
Add the mass value to the part or part set, besides the mass calculated from the part's structure.
Use this to account for additional components that will be attached to the part or part set during production, but are not currently part of your model. For example, a speaker for a car's interior door panel.
Important: Only available when the selected entity is a part or part set.
Total mass
The mass value is the total mass of the part or the part set, including structure and any additional parts that would be added in production but are not currently modeled. Masses that are calculated from the part's structure are ignored, and assumed to be part of the total mass value.
Important: Only available when the selected entity is a part or part set.
visualization node Select a node to display the mass handle in the modeling window.

Radioss: Available when a set is created, regardless of the other options chosen.

LS-DYNA: Available when a component or set is selected.

Update Subpanel

Option Action
mass update Change the mass value and type of a selected mass element.
connectivity update Update the entities on which the selected mass element is defined The choice for entity selection to update is limited to the type of entity that already exists in the selected element.

LS-DYNA: If the selected element has just a node or a component and you add more than one entity of same type then the selected entities by default is converted to a set and is associated with mass.

visualization node update Update the visualization node associated with the selected mass element.
