Shape V1 only knew about pipes. Shape V2 is a general model for 3D geometry: you give it any CAD part, a bracket, a housing, a manifold, a valve, and it learns to understand the shape on its own, without anyone labelling it first. Today we are opening up the model and a live demo so anyone can try it on their own parts.
Why this matters for CFD
The goal is to let the model make the decisions a CFD engineer would make. Reading a part and deciding that a symmetry plane lets you simulate half the domain, that a repeated sector lets you simulate one blade instead of thirty, that a junction needs local refinement, that this part is similar enough to a previously simulated one to inherit its mesh strategy, these are engineering calls, not meshing tricks. Shape V2 is the first step toward a model that makes those calls directly from the geometry, so the simulation loop can run without a human in the middle for every new part.
The interactive demo
The live demo at shape.simd.space lets you upload any CAD part, hide half of it, and watch the model predict the missing regions. The viewer shows an error heatmap on the reconstructed part, green where the prediction is accurate, yellow where it is partial, red where the model was wrong, so you can judge for yourself how well the model generalises to geometry it has never seen before.
