Implementations of the present disclosure include methods, systems, and computer-readable storage mediums for model-to-model transformation including actions of providing a source meta-model, the source meta-model having a plurality of classes and one or more references, receiving first user input to a graphical editor, processing the first user input to provide a plurality of class modules and one or more reference modules, each class module corresponding to a class of the plurality of classes and each reference module corresponding to a reference of the one or more references, automatically generating transformation code based on the plurality of class modules and the one or more reference modules, receiving a source model, the source model being provided based on the source meta-model and being provided in a computer-readable file that is stored in memory, and generating a simulation model based on the source model and the transformation code.
