# Tutorial: How to optimize design using SW Simulation?

optimize design

1. ### Step 1:

Create model by this drawing in SW

2. ### Step 2:

Launch SW simulation module

3. ### Step 3:

Create new static study

5. ### Step 5:

fix detail as shown in the drawing
Add fixed hinge in 4 holes

6. ### Step 6:

fix detail as shown in the drawing

Create mesh

9. ### Step 9:

Start calculations

10. ### Step 10:

We get results
Maximum stress is 96.056 MPa
On the back wall there is almost no load. Material used there in vain. So we remove the part of material. In this case stress will not change much. But we will save material.

11. ### Step 11:

Create sketch and cup some material from back wall.

12. ### Step 12:

recalculate detail
It became better resist stress
Weight decreased by 200 grams

13. ### Step 13:

Now optimize the dimensions B1 and B2
Crete new design study

14. ### Step 14:

Add new variable in design study. select dimension B2 like on snapshot, input name of variable and click apply & OK. New variable appears in the table.

15. ### Step 15:

In such way add variable B1. All you steps on snapshot

16. ### Step 16:

Now set parameters of those variable.
I want that they are have changed from 4mm to 10mm in steps of 0.5mm
We get 169 combinations.

17. ### Step 17:

Click on appropriate field and add new sensor. We need to control simulation data – Max stress by VON in MPa for all model.

18. ### Step 18:

Set parameters of this sensor. We need to value is in the range from 110 to 120 MPa.

19. ### Step 19:

We need to minimize weight of detail.

20. ### Step 20:

After adding this parameter on screen we will see something like this.
All parameter of study is set.
Start it!
ATTENTION: This study takes a lot of time and disk space on your PC. I have spent 16 GB of space

21. ### Step 21:

In this attention window click “YES”

22. ### Step 22:

After calculation you get table with results.
Optimal parameters is: B1=4.5mm B2=9mm.
Stress 115.467 MPa
Weight 1.829 kg

23. ### Step 23:

Optimized detail looks like this
It took off weight by 20 percent
It’s good result.
