2d case - flow spreads radial from a point

Hello, does anyone understand why this happens?

It’s a 2d case and i set a wind vector in the (-)y direction with a magnitude of 5. It seems like the flow spreads from a point.

I upload the GH file in case it’s needed.

Plan.gh (62.2 KB)

From the image screenshot, you provided prob’s (mesh) points to _analysisResult values or as vectors input. And it’s not CFD result.
Use Butterfly_Load Probes Value component to load from solution and connect the outputs to relevant input for visualizing results.


My bad, i thought to have followed properly the example file but in the end it appears i wrong the final part.

Thanks for the help
