💡 Hint

Common Mistakes

Using stop() instead of run()

Using pause() before starting

Using reset() which clears the setup

Use run() to start the simulation process in SolidWorks.

2fill in blank

medium

Complete the code to retrieve the maximum stress result after simulation.

Solidworks

max_stress = results.[1]('MaxStress')

Drag options to blanks, or click blank then click option'

AgetResult

BgetValue

CfetchData

Dretrieve

Attempts:

3 left

💡 Hint

Common Mistakes

Using getValue() which may not exist

Using fetchData() which is not a SolidWorks method

Using retrieve() which is not standard

The getResult() method fetches specific simulation results like maximum stress.

3fill in blank

hard

Fix the error in the code to correctly check if the simulation has converged.

Solidworks

if simulation.[1] == True:
    print('Simulation converged')

Drag options to blanks, or click blank then click option'

AhasConverged

Bconverged

CcheckConvergence()

DisConverged()

Attempts:

3 left

💡 Hint

Common Mistakes

Using method calls instead of property

Using incorrect method names

Checking a method without parentheses

The property hasConverged returns a boolean indicating convergence status.

4fill in blank

hard

Fill both blanks to extract displacement and check if it exceeds a limit.

Solidworks

displacement = results.[1]('MaxDisplacement')
if displacement [2] limit:
    alert('Displacement too high')

Drag options to blanks, or click blank then click option'

AgetResult

B>

C<

DfetchValue

Attempts:

3 left

💡 Hint

Common Mistakes

Using fetchValue which is not standard

Using < instead of > for checking if displacement is too high

Use getResult to get displacement and > to check if it exceeds the limit.

5fill in blank

hard

Fill all three blanks to calculate safety factor and decide if design is safe.

Solidworks

safety_factor = results.[1]('SafetyFactor')
if safety_factor [2] threshold:
    status = '[3]'
else:
    status = 'Unsafe'

Drag options to blanks, or click blank then click option'

AgetResult

B>=

CSafe

DfetchResult

Attempts:

3 left

💡 Hint

Common Mistakes

Using fetchResult which is not standard

Using < instead of >= for safety check

Setting status to 'Unsafe' incorrectly

Use getResult to get safety factor, compare with >= threshold, and set status to 'Safe' if condition passes.

Practice

1. What is the main purpose of running a simulation in SolidWorks before building a physical part?

easy

A. To test the design virtually and find potential problems early

B. To create a 3D model faster

C. To print the part automatically

D. To change the color of the design

Solution

1. Step 1: Understand simulation purpose

   Simulations help check how a design behaves under conditions without making a physical part.

2. Step 2: Identify benefits of early testing

   Finding problems early saves time and money by avoiding costly physical errors.

3. Final Answer:

   To test the design virtually and find potential problems early -> Option A

4. Quick Check:

   Simulation = early problem detection [OK]

Hint: Simulations find design issues before building [OK]

Common Mistakes:

• Thinking simulation creates physical parts
• Confusing simulation with 3D modeling speed
• Believing simulation changes design colors

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

easy

A. Go to Simulation tab, click 'New Study', select 'Static', then click OK

B. Go to File menu, select 'Export', then choose 'Static Simulation'

C. Right-click the part and select 'Run Simulation' directly

D. Open the part and press Ctrl+S to start simulation

Solution

1. Step 1: Locate Simulation tab

   Simulation studies start from the Simulation tab in SolidWorks interface.

2. Step 2: Create new static study

   Select 'New Study', then choose 'Static' to analyze forces and stresses under steady loads.

3. Final Answer:

   Go to Simulation tab, click 'New Study', select 'Static', then click OK -> Option A

4. Quick Check:

   Simulation tab + New Study = start static study [OK]

Hint: Use Simulation tab > New Study > Static to start [OK]

Common Mistakes:

• Trying to export instead of creating study
• Right-click menu does not start simulation
• Saving file does not run simulation

3. After running a simulation, you see a color map showing red areas on your part. What does the red color usually indicate?

medium

A. Areas with the lowest stress

B. Areas that are not part of the simulation

C. Areas with no stress

D. Areas with the highest stress

Solution

1. Step 1: Understand color map meaning

   Simulation results use colors to show stress levels; red usually means high stress.

2. Step 2: Interpret red color

   Red areas are critical points where the part experiences maximum stress and risk of failure.

3. Final Answer:

   Areas with the highest stress -> Option D

4. Quick Check:

   Red color = high stress [OK]

Hint: Red means highest stress on the part [OK]

Common Mistakes:

• Confusing red with low stress
• Thinking red means no stress
• Ignoring color legend in results

4. You ran a simulation but the results show zero stress everywhere, which seems incorrect. What is the most likely cause?

medium

A. The part is too small to simulate

B. You forgot to apply loads or fixtures to the model

C. The simulation ran too long

D. You used the wrong color scheme

Solution

1. Step 1: Check simulation setup

   Stress results depend on applied loads and constraints; missing these causes zero stress.

2. Step 2: Identify missing inputs

   Without loads or fixtures, the part is free and unstressed, so results show zero everywhere.

3. Final Answer:

   You forgot to apply loads or fixtures to the model -> Option B

4. Quick Check:

   No loads = zero stress [OK]

Hint: Always apply loads and fixtures before running simulation [OK]

Common Mistakes:

• Assuming part size affects stress values directly
• Thinking simulation time affects stress results
• Blaming color scheme for zero stress

5. You want to improve a design after simulation shows high stress in a small area. Which approach is best to reduce stress based on simulation results?

hard

A. Remove all fixtures to let the part move freely

B. Change the material color to blue

C. Add fillets or rounds to smooth sharp corners in the high-stress area

D. Ignore the results and build the part as is

Solution

1. Step 1: Analyze high-stress area cause

   Sharp corners cause stress concentration; smoothing them reduces stress.

2. Step 2: Apply design improvement

   Adding fillets or rounds distributes stress more evenly and lowers peak stress.

3. Final Answer:

   Add fillets or rounds to smooth sharp corners in the high-stress area -> Option C

4. Quick Check:

   Smoothing corners reduces stress [OK]

Hint: Smooth sharp corners to lower stress [OK]

Common Mistakes:

• Changing color does not affect stress
• Removing fixtures causes unrealistic results
• Ignoring simulation feedback wastes improvement chance
