Clearing Sequences and Deleting Sequences or Nodes
You can change the contents, and actions, of the sequences in the model tree by clearing a meshing sequence or solution under a solver configuration, or delete nodes in the Model Builder.
Undo is not possible for nodes that are built directly, such as geometry objects, meshes, solutions, and plots.
Clear or Delete a Mesh
Use a Clear function to keep the nodes and be able to recreate the mesh by rebuilding the meshing sequence.
Under the Component node where you want to clear or delete the mesh:
•
In the Mesh toolbar, click Clear Mesh () or right-click the Mesh node and select Clear Mesh ().
•
To delete a meshing sequence, in the Mesh toolbar click Delete Sequence () or right-click the Mesh node and select Delete Sequence ().
•
If you have a model geometry with several meshes, you can clear all meshes at the same time. From the Mesh toolbar, click Clear All Meshes ().
Clear or Delete a Solution
Use a Clear function to keep the nodes and be able to recreate the solution by computing the solution again.
•
To clear a set of solutions under a specific study, from the Study toolbar, click Clear Solutions () or right-click the Study node and select Clear Solutions ().
•
To delete all solver nodes, right-click the Solver Configurations node and select Delete Configurations (). You can also choose whether or not to remove the Results nodes (datasets and plots, for example) associated with the solver configuration.
•
If you have a model geometry with several studies, you can clear all solutions in all studies at the same time. From the Study toolbar, click Clear All Solutions ().
Delete Nodes
•
To delete selected nodes, right-click the nodes and select Delete () or press Del (the Delete key). Confirm the deletion of nodes for it to take effect. Also see Clear or Delete a Mesh.
•
To delete a geometry sequence, in the Geometry toolbar click Delete Sequence () or right-click the Geometry node and select Delete Sequence (). You cannot use the Undo command.
•
To delete geometry objects or entities, in the Geometry toolbar click Delete () or right-click Geometry and select Delete (). Or select objects in the Graphics window, and click the Delete button () in the Graphics window toolbar.
If you use the Delete button to delete objects, the software deletes the selected objects that correspond to primitive features by deleting their nodes from the geometry sequence. If you delete objects that do not correspond to primitive features or if you delete geometric entities, a Delete Entities node appears in the sequence.
