Altair Inspire® Challenge #6: Lilly Pad Optimization

Matthew_Sauer1

This challenge is to run a topology optimization on the base of the Water Lilly Pad that is supported at its centre, with water pressure loads in the vertical and horizontal directions.

Note that the location of the ribs in nature is not purely based off of achieving maximum stiffness, or minimum mass, but also considers nutrient transport, and other functions necessary to the plant.  We will be focusing exclusively on the structural aspects of the rib layout for this challenge.  Your objective is to maximize the stiffness while reducing mass.

The attached STMOD file is your starting point.  Feel free to adjust the design space, manufacturing constraints, and optimization settings to come up with the ideal massing.

Level: Easy

Product Required: Altair Inspire

The solution can be attached in the comment section of this post. The desired output format is a PNG or JPG showing the optimized rib layout, and analysis results.

Hi Mathew & everyone, i found this tricky, the optimization solution does leaves a huge gap between the outer ring (partition) and the design space. Please advice

Hi there,

Have you experimented with different min and max thickness values?  Do you notice a different distribution of the optimized massing?  In the interest of fairness for this challenge, I do not want to give too much away, but that may be something worth investigating.

Great work!

Dear sir,

I have done optimization of Lilly pad in three different ways (by changing manufacturing constraints, and optimization settings).  please check the results

Great work, Sakshi!  Impressive results.

Ok,

Here is my try:

1. basic

2. With Frequency Constraints

3. Topography optimation

 

4. With only 3 sectors in shape control

I like it, thank you for showcasing the different outcomes Karli!
