An embodiment constructs a simulation model of a release system based on experimental data such as imaging and determines a model predicting a release profile through use of an iterative process. The process iterates: (i) modifying parameters of the constructed simulation model based upon release system mechanistic characteristic data to correct a transport coefficient of the release system and (ii) performing a simulation of the release system using the constructed simulation model with the modified parameters to generate a simulation-based release profile, until a given simulation-based release profile that matches the release system characteristic data is identified. The constructed simulation model with the modified parameters used to generate the matching simulation-based release profile is set as the model predicting the release profile of the substance from the material matrix.
