Cantera in Simulink

[Lucas van de Voorde]

Hi,

I try to use Cantera in Simulink. I have a written a simple matlab function in a Simulink block

For now I try to import an phase in that function. But I get this error message from Simulink:

"Cannot load 'Solution' because code generation does not support classes and enumerations in @-directories."

If I try to import the phase in the command windows of Matlab everything works fine, but not in Simulink.

Can anyone help me?

Greets,

Lucas

Lucas,

I would expect this is because all of the Cantera classes are defined in @ folders. This is documented here: https://www.mathworks.com/help/matlab/matlab_oop/class-files-and-folders.html There are actually several OOP paradigms in Matlab, and Cantera uses one of the older ones, so its possible that upgrading would allow you to use Cantera with Simulink. However, I'm not sure if its possible to use user-defined classes at all in Simulink, so this is something you'll have to investigate.

Best regards,

Bryan

Thanks Bryan for your responce. 

I found another solution.

Just add: coder.extrinsic('matlab_function') to your matlab function block. And replace matlab function by the file name of the function in which you are using Cantera files.

Hi,

The open source Toolbox for the Modeling and Analysis of Thermodynamic Systems (T-MATS) has this interface set up.
You could use it as created, or use it as a reference of one method of using Cantera with Simulink.

The software/source code can be found at: https://github.com/nasa/T-MATS

Hi Lucas,

I am facing similar issue.

Can show me an example. I am trying to run constant volume combustion through simulink.

Thanks
