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

• speed of sound in steel rail=___5188.745 MM/MS____

sol: formula for sound : C = sqrt(E/RHO)

• the time takes for a shock wave to travel from one end of the rail to the other= 0.1927 ms

SOL : LENGTH OF RAIL :1000MM, TOTAL TIME FOR SHOCK TO TRAVEL L/C( LENGTH OF RAIL /SPEED OF SOUND)

• Time for sound to travel length of rail=_0.1927 ms
• THE ABOVE CALCULATION VALUES ARE EDITED IN THE ENGINE FILE.

• SETTING THE FREQUENCY OF ANIMATION : TIME TAKEN FOR PROPAGATION/ TIME STEPS = 0.009636 MS

3D MESH

• The model hub which is to be done 3d meshing with tetra elements.
• with size 5 mm, tet collapse =0.15.

• THE ONE WITH ARM BRACKET NEED TO PERFORM HEX MESH WITH 10MM ELEMENT SIZE.
