Shell , 2D Plate Element Type, 2D Solid Element Type
The name of this option varies according to your model type. Select one of the following items from this option menu:
• Quad and Tri—AutoGEM creates a combination of quadrilateral and triangular elements when you create elements using the Surface menu option. For most models, this is the best choice.
• Tri—AutoGEM creates only triangular elements when you create elements using the Surface menu option. Select this option if you want shells that are compatible with the tetrahedral solids that the Volume menu option creates.
