nTop Live: Optimizing Lattice Structures for Damping Vibrations on Aerospace and Automotive Parts

Being able to create a modal analysis study is necessary when designing automotive combustion engines or UAV mufflers. In fact, such studies are required for aerospace and spacecraft applications to analyze mode shapes and natural frequencies, where subsequent results can be used to dampen vibrations caused by atmospheric drag on wings or other dynamically loaded components.
In this nTop Live, Siddhant Chandgadkar, will demonstrate how to perform modal analysis studies with various lattice configurations within nTop Platform by using a relative density-based reusable workflow. These lattice configurations include a step-based and ramp-based gradient change of relative densities through the entire test model.
Watch and learn how to:
- Thicken lattice structures based on relative densities instead of beam-based thickening in a reusable workflow
- How to develop a more efficient workflow using FE lattice meshes for a modal analysis
- Set up a DoE with nTopCL using Python to repeat the simulation workflow passively

Wow, great video! The speaker spoke with clarity and coherence that was easy to follow. He did a really good job breaking down the concepts pertaining to this topic for a layman like me.

Hi, please help me, how to input the relative density in creating a TPMS?
Thanks

[@panweijiang7609]

How to call the block that can directly build the lattice in a cylinder with relative density? Is it from a custom lattice block?

How can i use an output variable in my Python-code?

[@StellaSimoesO]

Hi! Can you tell me the name of the software that you use to do this lattice structures?

[@himprakashdas4482]

i am not being able to make a lattice with even number of unit cells. HELP
