12.3.7. Primitive Mesh

Primitive Mesh is 3D mappable mesh for the primitive geometries (box, ellipsoid, cylinder and cylinder). It calculate the node positions using geometry parameters (the width, height and depth of a box, the radius of a sphere etc.). It considers both the surface and the volume mesh. Node positions are symmetric in the possible area.

12.3.7.1. Ellipsoid Primitive Mesh

The target geometry ellipsoid is divided into two partitions. One is inside box shape. Another is outside ellipsoid shape without box shape. The element type is hex. The node positions are calculated using the ellipsoid radius, inside and outside segments and inside ratio. The node positions are symmetric in the x, y and z direction.

• Target Geometry: Shows a target geometry to apply the ellipsoid primitive mesh. Only ellipsoid geometries can be selected. Ellipsoid primitive mesh is applied to the mesh of the geometry.

• Radius: It shows the properties of the geometry ellipsoid.

• Property: Select the property to apply to the mesh. Only solid property can be selected.

• Inside Ratio: It the ratio of the edge length of a cube to the diameter of an ellipsoid.

• Inside No. of Segments: It’s number of segments of the inside box mesh.

• Outside No. of Segments: It’s number of segments of the outside ellipsoid mesh.
