Hi, I’ve a Grasshopper simulation of a hexagonal unit cell that can tessellate to form a larger auxetic sheet. Currently I can just solve everything geometrically, but I wanted to ask if it is possible to simulate, in an alternative way, the opening of the sheet using Kangaroo. [HexCell_simple] He…

Hi @jasonlim If you input all the tiles joined together as a single mesh to RigidBody, it will treat that whole mesh as rigid. To have the tiles able to move relative to each other, each tile needs to be a body. Also, RigidBody defaults to the volume centroid of the meshes as the frame for that b…

Hi that makes sense. Thank you Daniel

Hi Daniel, I am trying to prevent collisions between the tiles and have tried rigidbody collisions in Kangaroo. However, it doesn’t seem to be working. Am I doing it correctly? [image] Unit_cell_hex_internalised_dp3.gh (47.5 KB)

Have a look at this example [dissection] [image] Rigid curve collisions Kangaroo One more little play with this - some hinged dissection: [dissection] hinged_dissection_example.gh (21.1 KB)

Hi @DanielPiker ! This is beautiful. I’m testing this to map the kinematics on to a surface. Is there another way you would do this? If the surface curvature is too much the connections break. [image] [image]
