VDIMU10AXIS: Idealized model of a real world multi axle IMU (Inertial Measurement Unit) that includes:
- an accelerometer (3 axis)
- a gyroscope (3 axis)
- a magnetometer (3 axis)
- a barometer (scalar)
for a total of 10 measured scalars, hence the name 10-axis Inertial Measurement Unit (TRN-2513).
VDSWIFTCONFIG: Optional submodel to configure the Amesim / MF-Swift interface. You can specify alternate location (and alternate versions) for the MF-Swift SDK as well numerical settings (TRN-3321).
