**There are many mesh improvement tools available in ANSA. The Split tool is one of them. In ANSA GUI, the Split option can be found under ELEMENTS in the MESH deck. (Refer below image)**

The Split command is used to divide a Quad element into two Tria or Quad elements.

- Basically, the
**Split**command is used by three methods.

1) Split by Nodes

2) Split by Edges

3) Split by both Nodes and Edges

Let's understand these methods with examples.

**This method uses two nodes to split one Quad element into two Tria elements. Refer to the below Image for an explanation.G**

** ***Image 2: Split by Nodes demonstration*

*Let’s take another example and see how Split by Nodes option can be used to eliminate Quad elements. Refer to the below image for an explanation.*

* Image 3: Split by Nodes demonstration*

**Important****: **

- The
**Join**option is used to remove the edge and to convert two side-by-side Tria into Quad elements. - The
**Join**option can also be performed by the**Split**option with a right mouse click. - The
**Smooth**option must be used after using any Mesh optimization tools. It will smoothen the mesh flow by adjusting the nodes.

**This method uses Edge to split one Quad element into two Quad elements. Refer to the below Image for an explanation.**

** Image 4: Split by Edges demonstration**

**Note:**

- To perform the
**Split**option, Do Left click on the edges and then Confirm the action by pressing the scroll button of the mouse. Always perform a Smooth option after Splitting edges for better Mesh quality. - Let’s take another example and see how the
**Split by Edges**option can be used to eliminate Tria elements. Refer to the below image for an explanation.

*Image 5: Split by Edges demonstration*

**This method is a combination of the above methods. It uses two nodes to split one Quad element into two Tria elements followed by the splitting of Edge. Refer to the below image for explanation.**

** Image 6: Split by both Nodes and Edges demonstration**

**Let’s take another example and see how the Split by Nodes and Edges option can be used to eliminate Rotating Quad and Tria elements. Refer to below image for an explanation.**

** Image 7: Split by both Nodes and Edges demonstration**

**Important:**

- The selection of the method will be totally dependent on the Mesh orientation.
- Every time you use the
**Split**tool, it is advisable to use a**smooth**option for better Mesh flow.

Reynold's law of Similarity

The Reynolds number represents the ratio of inertial to viscous forces and is a convenient parameter for predicting whether a flow condition will be laminar or turbulent. It is defined as the product of the characteristic length and the characteristic velocity divided by the kinematic viscosity.
