Assignment 3-2D Element Formulation Challenge

Aim :

The aim is to compare of results with base simulation and improved shell element properties.

Objective:

1.Using the crash beam file from the previous assignment, change the run time to 55 ms.

2. Change the number of animation steps during simulation to a minimum of 25 and maximum of 60.

3. Run the base simulation without any modification to element properties.

4. At the end of the simulation, do the energy error and mass error checks and determine whether results would be acceptable.

5. If acceptable, Plot rigid wall forces, internal energy, hourglass energy, contact energy, total energy of the simulations.

6. Change all the shell elements properties to recommended properties, save this as separate, rad files and run the simulation.

7. Follow steps 5 and 6.

8. Create a brief report comparing all the results from steps 5 and 6 for both simulations.

9. Comment whether there is any change in the results and why there is any change in the result.

Procedure:

Initially import the given file with the solver deck and import it,

then change the number step of eng data as shown below,

then run the radioss file ,

then go to file and load the result and read the .h3d file,

For the crash simuation above are given the best results.

Result:

Thus the file has been completed the given objective.
