API - Geometry Mappings

I am using the C# API to automatically upload and solve flow around an aerofoil.
The CAD has been drawn using the NX Open API and I am now trying to create boundary conditions with this.
However, I am struggling to add my list of values to the entities list. I keep getting the ‘Unhandled number of Entities’ exception. My thinking is that the names I am using for the NX part are different to the ones SimScale are looking for.

Does you have any known solutions for NX and SimScale uses?
