| 1. | Select the solid elements subpanel. | 
| 2. | Indicate the elements you want to split: | 
| • | Pick the elements on your model. | 
or
| • | Click elems and choose from the extended entity selection menu. | 

| 3. | Choose the pattern to use when splitting the elements (See Comments). | 
| 4. | Click split. | 

In this example, the elements were split into hexas.
The three available patterns include:
| • | Splitting the solid elements into hexas | 
| • | Splitting the solid elements into a minimal number of tetras | 
| • | Splitting the solids into symmetric sets of tetras suitable for CFD | 
When you split elements whose nodes are associated to a surface, the new nodes created are also on the surface. To associate a node to a surface, use the Node Edit panel.
All split operators work on both first and second order elements.
