Assignment 2-RADIOSS Engine File Editing & 3D Meshing Challenge
AIM: Edit the engine file which is given for the challenge according to the questions given above.
ANSWERS:
1. The material properties for the steel are given in the file and shown in the below image.
Youngs modulus E=210000MPa,
Density ρ=0.0078.
Speed of sound in steel c= √(E/ρ)= √(210000/0.0078)= 5188.7452 mm/ms.
2. Given the length of rail L= 1000mm.
time takes to travel along the rail = L/c = 1000/5188.7452= 0.192ms.
3. The time for sound to travel along the rail = 0.192ms
as the length of the rail is 1000mm.
4,5 and 6.
The termination time is time calculated in question 2 i.e., 0.192ms
and for 20 animations we need divide the termination time with 20 and is equal to 0.009636
CONCLUSIONS: The engine file is edited according to the question given above.
3D MESHING CHALLENGE:
TETRA MESH FOR HOUSING:
AIM: To create the tetra mesh for the housing component given in the challenge.
PROCEDURE:
- Import the housing component given in the challenge to the hypermesh.
- It has 2 components cover and the hub, first hide the hub and do the tetra meshing for the cover.
- By selecting the element size as 5 give the volume tetra in the 3d mesh panel.
- Cover is meshed and shown in the figure by masking few elements.
- Hub is meshed and shown in the figure by masking few elements.
CONCLUSIONS: The tetra mesh has been done on the housing component.
3D HEXA MESHING:
AIM: To create the hexa mesh for the given arm bracket.
- The below figure shows the masked component which is meshed with hexa elements.
CONCLUSIONS: The given arm bracket is meshed with hexa elements.
