Assignment 2-RADIOSS Engine File Editing & 3D Meshing Challenge
Live Session
1. Check the material properties of the rail component and calculate the speed of sound in steel rail=_______
Unit followed is = gm-mm-ms
Material name= Steel
Density (`rho`)= 0.0078 gm/mm3
Young's modulus(E)= 210000 Mpa
Speed of sound in rail (c)= `root()(E/rho)=root()(210000/0.0078)=5188.7`mm/ms
2. The length of the rail is about 1000 mm.calculate the time takes for a shock wave to travel from one end of the rail to the other.
Length of rail= 1000mm
Speed of sound/ shock wave= 5188.7 mm/ms
Time taken for the shock wave to travel from one end to another end of rail= `1000/5188.7=0.1927`ms`
3.Time for sound to travel length of rail= 0.1927 ms
4.Edit the engine file so that the stress wave can be monitored, moving from one end of the rail to the other during impact -this will require a termination time equal to the time it takes for the sound to travel the length of the rail(set on/RUN card)
5.Set the frequency of animation output to a time that will give 20 animation steps(/ANIM/DT)
Frequency time = `(Animation)/(fps)=0.1927/20=0.009635`
6.Change /print -10.
7.3d meshing tetra mesh and hex mesh
- Repeat class examples and, maintain the quality.
- Target tet size=5mm,hex size=10mm,tet collapse=0.15.
- Tetra Mesh
- Hexa Mesh
Note: As told by Vineet sir I'm submitting this report just after the live session.
