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.
