Hypermesh 2D, 3D Brick and Tetra Meshing

1) E= 210000

rho = 0,0078

Speed of sound in steel rail = 5188mm/ms

2) 1000 / 5188 = 0,192 ms

3) 1000mm / 343 mm/ms (Speed of sound) = 2,91 ms

7) a) Arm Bracket

First the lines are projected to base

2D and 3D mesh is done accordingly.

Now we create arm curve 3d mesh using spin elements

Now we use extract face elements and move to arm straight and create 3d elements

With the node path and lines solid map is used to create 3d mesh for the boss component.

Afterwards connectivity issue is solved with equilavance function

Part doesnt have any quality, connectivity or duplicate element problem.

b ) Housing

with 5mm element size tria elements have been created.

min tetra size selected as 3 and tetra collapse as 0.15
