Well done for noticing and reporting this.
In 2.11.1, I’ve rewritten the profile area calculation method (since now not only rectangular facets are allowed), and 2-sided facets weren’t normalized correcttly for their double area. It means that for double-sided facets, like this one…
The pressure (in the profile plotter only) was 2 times the real pressure. (In other parts, like facet details, it was correct). I corrected this, and checked and the profile is correct again:
The fix will be in Molflow 2.11.2, or meanwhile a fixed intermediate version is available here (build-artifacts-windows then Download on the irght side)
