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.

Hi

Node merge has most likely made some elements unsuitable for FE (hence Jacobian error).

If the geometry is just touching between them, and the wires are bonded then try shared topology. See below

All the best
