Below are just rough notes regarding the steps to completing simulation accuracy.
Accuracy of Simulation Steps
Goal: 1 Week - Sept 3rd to complete all items

Timeline
...
1
...
Determine the accuracy of our simulations (Priority)
This has not been previous done, and possibly validate/invalidate current work
Possible method: use literature values to verify the setup of the simulation is correct
Does a similar geometry, test data, etc. exist for the chassis?
...
2
...
Review/Complete Mesh Convergence study
Check 1 vehicle collision for now
Consider all 12 after
...
Anyone FEA experience
...
Can be done now
~1 hour
...
3
...
Create a presentation and detail all definitions and screenshots to be reviewed.
Send slide deck and simulation file prior to meeting.

Project Due Date: September 3rd, 2021 |
See slide deck for list of tasks/updates and more relevant confluence page links:
No. | Task | Description |
|---|---|---|
1 | In-Depth Simulation Review with Advisors | Create a presentation that details all definitions and screenshots of the current FEA set-up to be reviewed by Advisors. Send slide deck and simulation file prior to the meeting |
2 | Mesh Convergence Study + Review | Perform mesh convergence study on 1 vehicle collision scenario. Create a presentation to be reviewed by Advisors. **Look for artifacts, checking residuals, continuity of stress between meshes |
3 | Validation Case with Literature Value | Find a literature value of a structural geometry to see if our simulation can generate the same results. **Main emphasis on static structural **Use our settings as much as possible |
4 | Review Past Simulation / Insert Geometry | Review past simulation files used to pass VDR and compare to current simulation. If time permits, insert geometry of current chassis into past simulation file/setup to see if results stay the same. |
5 | Meet with a Prof to learn proper FEA Set-Up | Reach out to a Professor to begin getting a Professor to review our FEA, too. Check Technical Elective Presentation for Solid Mechanics Profs |
