    Effective modeling of composite structures requires rigorous handling of anisotropy and heterogeneity. Mechanics of Structure Genome (MSG) represents a new unified approach to modeling composite structures. The principle of minimum information loss is used to construct the best structural models in terms of microstructural details. MSG simplifies composites modeling to answering three fundamental questions: 1) what is the original model needed for capturing relevant physics? 2) what is the model wanted for a particular design? 3) what is the smallest fundamental building block of the structure? MSG can capture details as needed without invalid scale separation and assumptions within scales. A companion code, SwiftComp, is developed as a constitutive modeling software for virtual testing of structures and materials or as a plugin for powering FEA codes (e,g, Abaqus, Ansys, Nastran) with efficient high-fidelity composites modeling capabilities. MSG is applicable to any structures and materials featuring heterogeneity and anisotropy.
