We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

new update: https://github.com/Ice-Citron/FEA-Physics_IA/tree/main/FP16%20archive%20-%20cords_flattened/Modified%20-%20fp16%20%2B%2075segment100mm

Update: I changed the coordinates manually, so that it fits the exemplar, as in all the nodes that are supposed to be in contact are now the very same. Yet the error still is as seen in the image below. Now assuming there is no more issue with the meshing, what can possibly be the issue with the armature not having contact with the rails? Maybe I should just try and do the conventional classic "em_contact" instead?
