I have a struct which defines constants and vectors for aerodynamics surfaces on an aircraft. How do I create a bus with a struct input?

Can you use stateflow?

Im not too familiar with Stateflow or using a bus... Here is what I have done so far

I have a struct called s2

Used the line below to create a bus object from s2 struct and changed the bus name to 's2Bus'

s2Bus = Simulink.Bus.createObject(s2);
s2Bus.busName = 's2Bus'

Then I went to model explorer, found my function, added data, and changed the data type to bus object, and added the name there as shown in the image below.

However now I am getting a s2bus error:

When you created the bus object using Simulink.Bus.createObject, a structure s2Bus and a bus object slBus1 are created. Assigning the bus name as 's2Bus' has only changed the field 'busName' in s2Bus structure but the name of bus object is still slBus1. (as you can see in below figure)

Hence, you need to set the datatype of bus input as Bus: slBus1.
