Split bi-quadratic into linear
|
|
******************************
|
|
|
|
This functionality allows to split bi-quadratic elements into
|
|
linear ones without creation of additional nodes.
|
|
|
|
So that
|
|
|
|
* bi-quadratic triangle will be split into 3 linear quadrangles;
|
|
* bi-quadratic quadrangle will be split into 4 linear quadrangles;
|
|
* tri-quadratic hexahedron will be split into 8 linear hexahedra;
|
|
* quadratic segments adjacent to the split bi-quadratic element will be split into 2 linear segments.

|
|
|
|
#. From the **Modification** menu choose the **Split bi-quadratic into linear** item or click *"Split bi-quadratic into linear"* button |img| in the toolbar.
|
|
|
|
|
|
The following dialog box shall appear:

#. Select a mesh, groups or sub-meshes in the Object Browser or in the Viewer.
|
|
#. Click the **Apply** or **Apply and Close** button.
