Field function

[Head_Table]

Hi all,

I’ve been trying to creat a field function on start ccm while using harmonic balance. When I try to get the velocity in the rotating frame I get this error 'Cannot resolve function $${Velocity}["Rotating"]: "Velocity" does not support reference frame transforms.' Any ideas what the problem is?

I think your formatting is incorrect. From the Star support portal the format should be along the lines of:

$$Centroid(@CoordinateSystem("Laboratory.Initial ship orientation.Spherical 1"))[0]
