Full assignment to data missing using multiple Simulink states within charts

Hiya,

I'm trying to simulate a circuit that contains one stateflow chart with multiple Simulink states within it. When using two or more Simulink states the following error gets returned

'Full assignment to data 'Out' is missing. Specify values for all elements of Stateflow chart locals and outputs. For more information, see Supported Operations for Vectors and Matrices. For structure types, a full assignment is not necessary when the type is specified as "Bus: typename" and not inherited or parameterized.'

The files are attached to open the code for Simulink and Matlab, the Matlab code contains some extra variables you can ignore (any variables for the ventricles).

I've done some reading but honestly have no clue what I can do to fix this problem. I've tried defining the output blocks as empty arrays within Matlab before running the simulation, using the same and different names for each output block.

Thank you to anyone that can help! I've been stuck on this for a couple days now :)

Did u resolved the issue?

I solved this problem by initializing the variable with "Initial value" in the model explorer screen

Looks like the solution is initializing the variable for the output in Model Explorer. Did that work?
