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 liner segments.

Mesh before and after splitting

To split bi-quadratic elements into linear:

1. From the Modification menu choose the Split bi-quadratic into linear item or click "Split bi-quadratic into linear" button in the toolbar.

   
   "Split bi-quadratic into linear" button

   The following dialog box shall appear:

   

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