Creating groups

In - MESH you can create groups of elements of different types and having definite - properties.

In MESH you + can create groups of elements of different types. To create a group of + elements + in the Mesh + menu select Create Group. +

To create any group + you should define the following:

To create a group of elements:

- -

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 +
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.

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. +

Standalone Group

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.

The box for creation of a Standalone + Group appears by default. 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 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.

2. Click the OK - button to confirm creation of your group or Cancel - to quit this dialog box.

Group on Geometry

To create a group on + geometry check Group on geometry + in the Group type field. Group on geometry contains the elements + of a certain type belonging to the selected + geometrical object. To define a group select in the Objet Browser + or in the 3D viewer a geometrical object from which the elements will + be taken. After confirmation of the operation MESH will create a new group + consisting of geometrical elements of the previously defined type.

+	+ In this picture the cells which belong to a certain face + are selected in green.
