chrono::fea::ChContactSurfaceNodeCloud Class Reference


Class which defines a contact surface for FEA elements.

Only xyz nodes in the FEA model are used as contact items for the collision detection. Might be an efficient option in case of dense tessellations (but misses the node-vs-face and edge-vs-edge cases)
