To create any group + you should define the following:

1. In the Mesh - menu select Create - Group. The following dialog box will appear:

This dialog box contains - the following fields which should be filled:
- -- -
Mesh: the name of the mesh whose elements - will form your group. You can enter the name manually or select your mesh - in the Objet Browser or in the 3D viewer.
Mesh: + the name of the mesh whose elements + will form your group. You can select your mesh in the Objet Browser or + in the 3D viewer.
Elements Type set of radio buttons allows - to select the type of elements which will form your group:

Name field allows to enter the - name of your new group.
Group type set of radio buttons allows - to select the type of your group:
Standalone group consisting - of mesh elements.
Group on geometry consisting of - geometrical elements. If you choose this type of group your dialog - box will change and it will look like as follows:
Name field allows to enter the name + of your new group.

SALOME Platform distinguishes + between the two Group types: Standalone + Group and Group on Geometry. +

In this dialog box you should enter the name - of the geometrical object (you can enter the name manually or select your - geometrical object in the Objet Browser or in the 3D viewer) from which - the elements will be taken. And after confirmation of the operation MESH - will create a new group consisting of geometrical elements of the previously - defined type.
+Standalone + Group consists of mesh elements, which you can define in two possible + ways.

Content field - allows to manually define the mesh elements which will form your - group. You can click on an element in the 3D viewer and it will be highlighted. - After that click the Add button - and the ID of this element will be added to the list. To remove a selected - element or elements from the list click the Remove - button. The Sort button - allows to sort the list of elements IDs. The Set - filter button allows to apply a definite filter to selection of - the elements of your group. See more about filters on the Selection - filter library page
Choosing them manually + with the mouse in the 3D Viewer. You can click on an element in the 3D + viewer and it will be highlighted. After that click the Add + button and the ID of this element will be added to the list.
Select from set of fields allows to - choose a submesh or an existing group whose elements of the previously - defined type will be added to the list of elements which will form your - group.
Applying Filters. The + Set filter button allows to apply + a definite filter to selection of the elements of your group. See more + about filters on the Selection + filter library page.
To remove a selected element or elements + from the list click the Remove button. + The Sort List button allows to + sort the list of IDs of mesh elements.
+ +Select from + set of fields allows to choose a submesh or an existing group whose + elements of the previously defined type will be added to the list of elements + which will form your group.
+ +Color Number + (integer only, ranging from 0 to 9999) - allows to assign to the group + a certain index, for example, defining boundary conditions. This feature + introduces a useful element of preprocessing in Mesh module. Note that + Color number attribute has nothing + to do with the colors used for the display of the elements of the group.
