Aim- to change the shape for the model geometry using morphing technique. Procedure- 1. go to morphing module and create a morphing box in the otho mode as shown in the figure. 2. increase the height of the above visible by selecting all the box points and translating by using move option. 3. create another morph box like…

Aim- To deploy connections in the FE model of a car side door. Procedure- 1. Make different PIDs for the different components of the door. Every single unconnected component is given a separate PID. 2. Give RB2 and cluster RB2 connections for required holes and near components.   3. create the hinge connection as…

Aim- to construct a tetra mesh for the Rear view mirror component. Procedure-  1. check for geometrical issues. 2. Go to mesh-> length and set up length to 1. 3. Set up the mesh parameters and mesh quality criterias. 4. Use spot mesh ortho tria elements to mesh the curved surfaces. 5. Use spot mesh tria…

The target element length for Model-1 is taken 2.5mm because 4mm was too large for that model and unchecked faces error was occurring otherwise.

Aim-  to generate 2D shell mesh for the plastic bottle cap model. Procedure- 1. go to checks-> geometry. Use auto fix to fix issues and manual fix remaining issues. 2. Perform geometric cleanup. 3. Use Middle, offset, Translate, Rotate, New and other different commands to generate the manual midsurface for the model. During…

Aim-  to generate 2D shell mesh on the midsurface of the hood modal. Procedure- 1. go to checks-> geometry. Use auto fix to fix issues and manual fix remaining issues. 2. Perform geometric cleanup. 3. Go to midsurface-> skin and uncheck the delete original faces option. 4. midsurface is generated without losing parent…

Title of the project- Yacht assembly and radar mast objective- to make use of advanced solidworks features and to learn solidworks through working with the project. In this project multiple complicated looking parts were made and assembled. Radar mast: isometric view- Front view- side view- top view- feature tree- other…

Title of the project- Assembly of the chopper and its photo realistic rendering. Objective- to make the model look more realistic and presentable using different tools. Introduction- in the past challenge, we completed assembly of an american chopper bike. In this project we level the model accurately and realistically.…

Objective- side impact test is an important safety check for the vehicle and it is performed in this assignment. Apart from this there are other output requests like: Sectional force in the cross member. Intrusion at B pillar, hinge pillar and fuel tank region. Provide recommendations on what can help to reduce Fuel tank…

Objective- front impact test is an important safety check for the vehicle and it is performed in this assignment. Apart from this there are other output requests like: Sectional force in the rails at location of indicated node 174247. Axial force received on the rails from bumper. Shotgun cross sectional forces. A pillar…

  Objectives: To Create the mesh for bumper assembly, mesh size should be 6mm. To Run the crash tube model as it is. To Change the Inacti=6 and run. To Create the type 11 contact and run. To Remove both notches and remove boundary condition on rigid body node then run. To Create a new notch in the middle, select the whole…

Objective- to find differences in material behaviour when certain materail properties are changed. Case 1: TOTAL NUMBER OF CYCLES : 49380 ELAPSED TIME = 158.09 s mass error = 0% energy error is in the range of -0.6% to 1.3% simulation pictures in order: From the simulation it is observed that crack propagates in a…

Objective- The objective of this challenge is to compare the differences in results found out between base simulations and modified simulations. Base simulation results: Improved simulation results: Hourglass energy in case of the improved element simulation is very less as compared to base simulation. Total energy change…

Objective- to answer questions based on radioss and to perform 3D meshing.
