Removing nodes and elements¶
In MESH you can remove nodes and all types of cells of your mesh.
Removing nodes¶
To remove a node:
Select your mesh in the Object Browser or in the 3D viewer.
From the Modification menu choose Remove and from the associated submenu select the Nodes, or just click “Remove nodes” button
in the toolbar.
The following dialog box will appear:
In this dialog box you can specify one or several nodes:
choose mesh nodes with the mouse in the 3D Viewer. It is possible to select a whole area with a mouse frame; or
input the node IDs directly in Node IDs field. The selected nodes will be highlighted in the viewer; or
apply Filters. Set filter button allows to apply a filter to the selection of nodes. See more about filters in the Selection filter library page.
Click Apply or Apply and Close to confirm deletion of the specified nodes.
Note
Be careful while removing nodes because if you remove a definite node of your mesh all adjacent elements will be also deleted.
Removing node with reconnection¶
This operation removes a node and changes surrounding faces in order to cover a hole appearing in the mesh. This operation applies to 2D triangle mesh only.
To remove a node:
Select your mesh in the Object Browser or in the 3D viewer.
From the Modification menu choose Remove and from the associated submenu select the Node with reconnection, or just click “Remove node with reconnection” button
in the toolbar.
The following dialog box will appear:
In this dialog box you can specify one node to remove:
choose a mesh node with the mouse in the 3D Viewer or
input the node ID directly in ID field. The selected node will be highlighted in the viewer.
Activate Preview to see how faces will change.
Click Apply or Apply and Close to confirm deletion of the specified node.
Removing orphan nodes¶
There is a quick way to remove all orphan (free) nodes.
To remove orphan nodes:
Select your mesh in the Object Browser or in the 3D viewer.
From the Modification menu choose Remove and from the associated submenu select Orphan Nodes, or just click “Remove orphan nodes” button
in the toolbar.
The following Warning message box will appear:
Confirm nodes removal by pressing “Yes” button.
Removing elements¶
To remove an element:
Select your mesh in the Object Browser or in the 3D viewer.
From the Modification menu choose Remove and from the associated submenu select the Elements, or just click “Remove elements” button
in the toolbar.The following dialog box will appear:
In this dialog box you can specify one or several elements:
choose mesh elements with the mouse in the 3D Viewer. It is possible to select a whole area with a mouse frame; or
input the element IDs directly in ID Elements field. The selected elements will be highlighted in the viewer; or
apply Filters. Set filter button allows to apply a filter to the selection of elements. See more about filters in the Selection filter library page.
Click Apply or Apply and Close to confirm deletion of the specified elements.

Clearing Mesh Data¶
To remove all nodes and all types of cells in your mesh at once:
Select your mesh in the Object Browser or in the 3D viewer.
From the Modification menu choose Remove and from the associated submenu select the Clear Mesh Data, or just click “Clear Mesh Data” button
in the toolbar. You can also right-click on the mesh in the Object Browser and select Clear Mesh Data in the pop-up menu.
Note
- This command works in a different way in different situations:
if the mesh is computed on a geometry, then Clear Mesh Data removes all elements and nodes.
if the mesh is not based on a geometry (imported, compound, created from scratch etc.), then Clear Mesh Data removes only the elements and nodes computed by algorithms. If no such elements or nodes have been created, can remove nothing.
