For the option: | Do the following: |
|---|---|
Current Part | Enter the rigid body to be replaced |
External System | Select either: ■An existing external system in the model ■Or Create an external system on the fly The “…” button can be used to invoke the ‘External System Cremod’ dialog, in order to create an external system as a replacement for the rigid body. Note: Only external systems with an MNF or an MD DB specified are supported for the swap operation. If the selected external system does not have either an MNF or an MD DB specified, then an error message will be shown, indicating that such external systems are not supported. |
External System Positioning | |
Align External System CM with CM of Current Part | Select to align the external system by comparing the center of mass and inertia tensor of the two bodies. The external system is: ■Positioned such that its center of mass (CM) is coincident with the flexible body CM. ■Oriented such that its principal inertia directions are coincident with the part's principal inertia directions. If the inertia properties of the two bodies are similar, this method closely aligns the external system with the rigid body. If the bodies are symmetric about a plane, this method may rotate the external system 180° from the rigid body. In this case, you can use the Flip about buttons to rotate the rigid body 180° back into position. |
Launch Precision Move Panel | Displays the Precision Move dialog box, which lets you move objects either by increments or to precise coordinates. |
3 Point Method | Select to specify three point pairs to define the location and orientation of the external system. A point pair consists of a point on the original rigid body and a point on replacement external system. The three points on each body must uniquely define a plane. The first point pair defines the location of the rigid body and the second and third points define the orientation. The external system is positioned by making the first point pair coincident. It is then oriented by making points 2 and 3 on the External System reside in the plane defined by points 2 and 3 on the rigid body. |
Flip about | Only available if you used Align External System CM with CM of Current Part. Select either of the following to rotate the flexible about the corresponding axis: ■X axis - Rotate external system 180° about its largest principal inertia direction. ■Y axis - Rotate external system 180° about its second largest principal inertia direction ■Z axis - Rotate external system 180° about its smallest principal inertia direction. |
View parts only | Select to display only the rigid body and its replacement external system. |
View topology | Select to display a representation of the rigid body and its connections to other parts. Learn more about Graphically Viewing Model Topology. |
Copy original part | Leave a copy of the rigid body in the modeling database. This is helpful if you want to reactivate the rigid body. |
For the option: | Do the following: |
|---|---|
Update table | Select to update the Marker and Node table with the changes you have made. |
Reset table | Select to reset the Marker and Node table to the original connections found. |
Node Finder | Select to display the Node Finder Dialog Box and search for nodes. |
Node ID/Apply | Enter a node ID, and then select Apply to replace the node in a selected row of the Marker and Node table with the node ID you entered. |
Move to node | Select to move the marker in the selected row of the Marker and Node table to the location of the specified node. |
Preserve expression | Select to maintain the parameterization of the marker in the selected row of the Marker and Node table. The parameterization would be specified through Adams View expressions. This will keep the marker at its parameterized position. |
Preserve location | Select to maintain the location of the marker in the selected row of the Marker and Node table. If a marker is not coincident with the attachment node, Adams Flex preserves the offset. This is helpful if you have defined a joint location on the marker. It keeps the joint from breaking. |
Number of digits | Enter the number of digits displayed to the right of the decimal point in the Marker and Node table. |
Sort By | Select how to sort the Marker and Node table based on the headings of the columns. For example, you can sort the table by the marker that is the most distant from its selected node. ■Marker - Sort alphabetically by marker name ■Connections - Sort by markers with connections ■Node ID - Sort by the ID of the node ■Interface - Sort by interface nodes ■Distance - Sort by markers most distant from the selected node |
Marker and Node Table | Displays the markers on the external system and the node to which the marker will be transferred on the replacement external system. ■Marker - All the markers on the rigid body that will be transferred to the external system. ■Connections - All the forces and joints on the rigid body that use the marker for their definitions. These joints and forces will be transferred to the external system. ■Node ID - The attachment node chosen for the marker when it is transferred to the external system. When Adams Flex initially creates the table, it chooses the closest node. You can change the chosen node using the Node ID text box. ■Interface - An asterisk (*) in this column indicates that the chosen attachment node is an interface node. ■Relative Location - The x,y,z coordinates of the chosen attachment node relative to the marker's current position, resolved in the marker's coordinate system. A perfect match is 0. ■Distance - The magnitude of the relative location vector. ■Move column - Indicates how Adams Flex will position the marker. The three options are: ■move - When Adams Flex transfers the marker to the external system, it will move it to the chosen attachment node. How far the marker will be moved is given in the Distance column. ■loc - The current location of the marker will be preserved. If the marker's position was defined by an Adams View expression, the parameterization will be lost. ■expr - If the marker's position is defined by an Adams View expression, the parameterization will be preserved. Otherwise, the marker's current position will be preserved. This is helpful if you have defined a joint location using the marker. It keeps the joint from breaking. Use the Move to node, Preserve location, and Preserve expression buttons to set the Move column value. |
