Dear colleagues I have used WSMCreateModel frequently and had not found any problem. Nevertheless, while trying to generate a model with 14 state variables, 14 inputs and 4 outputs the model will not be generated, is there a limit in dimensions in the WSMCreateModel??.

Could anyone give a clue about why is this not working in this case? Regards Jesus

Here, it is my model
