Hello everyone,
I’m working on a B767-200ER model, and after updating to OpenVSP 3.46.0, I’m getting very sharp Cp spikes at the wing mid-span and at control-surface edges.
These spikes disappear when I run the same model in older versions.
I tried checking for duplicate surfaces, surface normals, mesh size, etc., but the spikes are still there.
I’ve attached my model.
Can anyone advise if this is a known issue or if I should change something in the geometry/mesh? I would like to know if it's normal or am I missing something? thanks. I have attached the vsp3 file

This is a post-processing artifact in generating the spanwise loads. It does not reflect a problem with the overall solution or the total loads. It mostly doesn't matter.
