Hello,
I have a problem setting up a vehicle model using the 6 DOF vehicle body. The error message I get is:
Matrix multiply dimensions propagation error. Error occurred while setting input port 1 of '/Vehicle Body 6DOF/Aero Drag/Inertial to Body' to have the dimensions [3 x 3]. A possible cause for this error is that these dimensions do not agree with the partial dimensions information present on other ports
and
Error in port widths or dimensions. Output port 1 of '/Vehicle Body 6DOF/Aero Drag/DCM' is a [3x3] matrix.
In the information section on the model in the simulink documentation, there is mentioned that the Windxyz input should be a [1x3] or [3x1] array. For both possibilities I recieve the same error message, also a [3x3] matrix is not working. The other input port is a earlier defined output in the model which I am not able or supposed to change the dimensions.
Did someone encounter this problem already with this block or am I missing something.
Thanks in advance

Hi Tom and Jaime,
Apologies for the late response and that you ran into this error - if anyone else reading this runs into such an error, please attach your vehicle model to help understand the issue better.
