Identify grasshopper plugin | plugins for topology optimization in 2025?

Hello everyone,

I am interested in learning how to use grasshopper for topology optimization.

I found a promotion video for a 595€ video course which covers this topic. As a student I can’t afford this so I would like to know If someone can explain or identify the workflow and/or the used grasshopper plugin from the video. I also found this linkedin Post which also is about this course. In the comments one person describes the workflow as “Voxels > Mesh > SubD > Nurbs”. Maybe this information helps to identify the workflow?

Screenshot at 0:07 from Video; I think here you can recognize some gh nodes:

Do you have other plugin recommendations for this topic? Now, after one hour of searching I found many plugins which are very old and don’t seem to get new updates for new rhino versions…

Hope to learn from you guys :smiling_face_with_sunglasses:
