Assignment 2-RADIOSS Engine File Editing & 3D Meshing Challenge

AIM:To study about the starter file and engine file in RADIOSS by changing the parameters for the given file and also perform the 3D meshing of the given components with given criterias.

OBJECTIVE:

1. Check the material properties of the rail component and calculate the speed of sound in steel rail=_______

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.

3.Time for sound to travel length of rail=______

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)

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

SOLUTION:

1.We can check the density and the youngs modulus fom the material tab.we can also find the both from the first rad file 0000.

speed of sound in the material=Root(210000/ 0.0078) = 5188.745 m/s.

2.time taken by the shock wave to travel = 1000/5188.75=0.192725 ms.

3.time to travel =0.192725 ms.

4.the engine file edited photo has been posted above.

5.frequency=0.1927/20=0.009636.

6.the change of photos has been posted above.
