How to Create FE without Surface in ANSA in 5 Minutes or Less

In this article we are going to see how to generate the elements or Fe Without creating a surface.

There are two options which will help us to generate the FE or Elements without any surface they are

1. Mesh Module > Shell Mesh Group > Fill Option
2. Mesh Module > Elements Group > Create

Fill Option:-

By Using this option we can create the 2d shell elements.

Let us see the utilisation of this option with the below examples.

Example-1:-

We need to create the FE for a Locator or the Dog-house in the IP-substrate model.

For Generating the FE for the Locator or Dog-house we need the CURVE’S or Points for the reference. We can use the Middle option from the curves group of Topo module to create outer periphery or boundary.

Select the Existing the cons of the ribs as shown in the below picture to generate the middle curve.

After the selection of two groups accept the selection by pressing the scroll button to generate the middle curve.

Similarly we need to do at the other rib side as well.

By using these two curves as the reference we can create the FE.

Fill option is available in the Shell Mesh group of Mesh Module

When you choose the Fill option a selection window will appear.

In Option list change the things as shown in the below image.

Select the Middle curves (For selecting the curves we use the left mouse click)

Accept the selection by pressing the scroll button or middle mouse button.

Reconstruct the Elements we will get them with proper mesh size.

Example-2:-

If we need to patch a hole in the FE as shown in the below image we can use the Fill option.

In previous example we have created the curves to define the outer boundary, whereas here we can use the existing element edges.

Choose the Fill option which is available in the Shell Mesh group of Mesh Module 

When you choose the Fill option a selection window will appear.

By default it will be in the Perimeters/Curves we need to change it to the Edges.

Select all the Edges at the patch.(selected edges will be highlighted in white color)

Accept the selection, it will generate the elements over there.

Create Option:-

By using this option at a time we can create only a single element. This option will help us to create the any 2d or 3d elements.
