2D And 3D Meshing

1. By using modulus and density value speed of sound value is calculated - 5661.385 m/s

2. For 1000mm rail length the element time step is 0.2 m/s

3. 0.2 m/s

7. 3D meshing Tetra mesh

procedure for 3D Tetra mesh:

1. In the hub component 2d mesh is created by giving element size as 5 mm and element type as trias.

2. After creating 2d mesh , 3d mesh is created in the hub component using tetra mesh option.

3.3d mesh is created in the cover component using volume tetra option. In that for 2d type its selected as trias and for 3d type selected as tetra mesh.

4. Tet collapse value 0.15 is given by using element check option.

3D mesh for Hex mesh:

Procedure for 3D hex mesh:

1.In the base component 2d mesh is created by giving element size as 10mm and element type as quad only.

2.By using element offset option hex mesh is created in the base component

3. Arm curve is meshed by using spin option and giving angle value as 90 degree

4.For hex mesh in arm straight, face component is activated in arm curce and 2d mesh created in oppsite surface of arm straight .By using linear solid option hex mesh is project from arm curve to arm straight.

5.In the boss component 2d mesh is created in one surface and its projected to destination surface by using solid map option .

6. After 3d hex mesh created , quad 4 element is deleted from the entire component.
