Why simulation validates designs in Solidworks - Dashboard Impact

Dashboard Mode - Why simulation validates designs

Business Question

How can simulation results help engineers confirm that their product designs will work safely and efficiently before building physical prototypes?

Sample Data: Simulation Results for a Mechanical Part

Test Case	Load (N)	Max Stress (MPa)	Max Displacement (mm)	Safety Factor
Case 1	500	120	0.5	2.5
Case 2	1000	240	1.0	1.25
Case 3	1500	360	1.5	0.83
Case 4	2000	480	2.0	0.63
Case 5	2500	600	2.5	0.50

Interactivity

A filter slider allows selecting a range of Load (N). When adjusted:

• The bar chart and line chart update to show only data points within the selected load range.
• The table filters to show only test cases within the load range.
• The KPI card recalculates the average safety factor for the filtered data.

Self Check

If you add a filter to show only test cases with Load less than or equal to 1500 N, which components update and what is the new average safety factor?

• Bar chart, line chart, table, and KPI card all update.
• New average safety factor = (2.5 + 1.25 + 0.83) / 3 = 1.53

Key Result

Dashboard shows how simulation results validate mechanical part designs by visualizing stress, displacement, and safety factor under different loads.

Practice

1. Why is simulation important in validating designs in SolidWorks?

easy

A. It replaces the need for any testing after production.

B. It automatically creates the final product without human input.

C. It helps find design problems early without building physical models.

D. It only improves the visual appearance of the design.

Solution

1. Step 1: Understand the purpose of simulation

   Simulation tests designs virtually to detect issues before physical creation.

2. Step 2: Compare options to simulation benefits

   Only It helps find design problems early without building physical models. correctly states simulation finds problems early without physical models.

3. Final Answer:

   It helps find design problems early without building physical models. -> Option C

4. Quick Check:

   Simulation finds early design issues = A [OK]

Hint: Simulation finds problems early, no physical model needed [OK]

Common Mistakes:

• Thinking simulation replaces all testing
• Believing simulation creates final product automatically
• Assuming simulation only improves looks

2. Which of the following is the correct way to start a simulation study in SolidWorks?

easy

A. Go to 'View' > Select 'Zoom' > Choose 'Simulation'

B. Open 'File' > Select 'Export' > Choose 'Simulation'

C. Right-click on the part > Select 'Paint' > Choose color

D. Click 'New' > Select 'Simulation' > Choose study type

Solution

1. Step 1: Recall the simulation workflow in SolidWorks

   Simulation studies start by creating a new study from the Simulation tab.

2. Step 2: Identify the correct menu sequence

   Click 'New' > Select 'Simulation' > Choose study type correctly describes starting a simulation: New > Simulation > Study type.

3. Final Answer:

   Click 'New' > Select 'Simulation' > Choose study type -> Option D

4. Quick Check:

   Start simulation via New > Simulation = D [OK]

Hint: Start simulation from 'New' then pick study type [OK]

Common Mistakes:

• Confusing export with starting simulation
• Selecting unrelated menus like Paint or Zoom
• Trying to start simulation from View menu

3. Given a simulation result showing high stress in a beam's middle section, what is the likely output interpretation?

medium

A. The middle section is the weakest point and may fail.

B. The beam will fail at the supports first.

C. The beam is safe everywhere with no risk.

D. Stress values are irrelevant to design safety.

Solution

1. Step 1: Analyze the stress distribution in simulation

   High stress areas indicate potential failure points in the design.

2. Step 2: Interpret the meaning of stress concentration

   The middle section with high stress is the weakest and likely to fail first.

3. Final Answer:

   The middle section is the weakest point and may fail. -> Option A

4. Quick Check:

   High stress = weak point = B [OK]

Hint: High stress means weak spot likely to fail [OK]

Common Mistakes:

• Assuming supports fail first without stress data
• Ignoring stress results as irrelevant
• Believing the beam is safe despite high stress

4. You run a simulation but get an error saying 'Mesh failed to generate'. What is the best way to fix this?

medium

A. Check and simplify the geometry to help mesh generation.

B. Restart the computer and try again.

C. Ignore the error and continue.

D. Change the color of the model to improve mesh.

Solution

1. Step 1: Understand mesh generation errors

   Mesh errors often occur due to complex or problematic geometry.

2. Step 2: Apply the best fix for mesh failure

   Simplifying geometry helps the software create a proper mesh for simulation.

3. Final Answer:

   Check and simplify the geometry to help mesh generation. -> Option A

4. Quick Check:

   Mesh error fix = simplify geometry = C [OK]

Hint: Simplify geometry to fix mesh errors [OK]

Common Mistakes:

• Ignoring errors and proceeding
• Restarting computer without checking geometry
• Changing model color expecting mesh fix

5. A design engineer uses simulation to test a new bracket under load. The simulation shows stress exceeding material limits in some areas. What should the engineer do next?

hard

A. Ignore the results and proceed to manufacturing.

B. Redesign the bracket to reduce stress concentrations.

C. Increase the applied load in simulation to test further.

D. Change the simulation software and rerun the test.

Solution

1. Step 1: Interpret simulation stress results

   Stress exceeding material limits means the design may fail under real conditions.

2. Step 2: Decide the appropriate action based on results

   The engineer should redesign to reduce stress and improve safety.

3. Final Answer:

   Redesign the bracket to reduce stress concentrations. -> Option B

4. Quick Check:

   Stress too high? Redesign needed = A [OK]

Hint: Redesign if stress exceeds material limits [OK]

Common Mistakes:

• Ignoring critical stress results
• Increasing load without fixing design
• Switching software instead of fixing design
