At present it is not possible to import dynamic neural networks to CAGE. The only neural networks supported in MBC are the neural network models fitted in MBCMODEL.
In general, CAGE is designed for steady-state problems so would not work well with dynamic models. One workaround that you could use if you are doing feature fill is to create a dataset with predictions from your dynamic neural network and import the data set to CAGE. if you have other applications in mind please let us know and we can consider them for future enhancements.
