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

1 speed of sound is `sqrt (E/rho` which when is put value E =210000 and 'rho' =0.0078

c = 5188.74

2 delta tc= l/c 1000/5188.74 = 0.1927

3 0.1927sec

4 and 5

3 D MESHING

1 CHECK IF THERE IS ANY EDGE THAT NEEDS TO BE TOGGLED OR IS CREATING ANY SINGLE CONS, IF NOT THEN NEXT STEP IS THAT AS THERE IS NO UNIFORM WIDTH SO WE CANT MID SURFACE THE COMPONENT SO SELECT ONE COMPONENT AND SEPERATE IT

AFTER SEPERATING GO TO THE 2D MODULE AND SELECT AUTO MESH AND IN AUTO MESH GO WITH TRIAS AND SELECT THE ELEMENT SIZE THAT YOU WANT.

THEN CLICK ON MESH AND DO THE SAME WITH THE OTHER PART AS WELL.

THEN GO TO THE 3 D MODULE AND CLICK ON TETRA MESH AND GO TO THE TETRA MESH PARAMETERS

WRITE THE DETAILS GIVEN IN THE QUESTION LIKE TETRA SIZE TET COLLAPSE AND GO BACK TO TETRA MESH MODULE

SELECT ONE BY ONE ELEMENT AND MESH THEM

IT WILL BE LIKE THIS

SAME STEPS ARE NEED TO BE FOLLOWED IN THE SECOND TASK

SECOND TASK

1 FIRST 2D MESH BUT THIS TIME ONLY QUADS AND ONLY UPPER SURFace

THEN GO TO THE 3D MODULE element offet and select the upper surface which was meshed and select any two adjacent surface

now we go to mask elements f5 and mask the box because we need 2d element not 3d element to go further seect the top surface and mask it the element will become 2 d

now select the second component for the curve we need to find the center point for that we will be using three point option

as we drag on a curve we can select any point on that line and after clicking on the three point we can click on circle center option given in the menu

center will be generated

and for 3d meshing we can use spin oprtion in the 3 d mesh module

for 2d elemets angle is always 90 and on spin option you have to write a number that how much elements you want on it

it will be something like this and for rest element you can apply the same rule.
