Can PLOT3D format grid files be imported into Caedium, or do I need to mesh my geometry starting with CAD output? Can the program accept x,y,z coordinate data (for turbine airfoils)?
[Edit: based on an email exchange]
Caedium can import PLOT3D format (.x) if it's an entire volume mesh.
Importing CAD geometry (preferred format STEP) is the best way to get geometry into Caedium.
You can import x, y, z coordinates using the .pts format - columns of ASCII coordinates (you can also supply just x, y) with empty newlines separating groups. Once in Caedium the points will be represented as groups of vertices which you can then select and fit splines through to define your airfoil profiles.
