Adaptive Multiscale Simulation Infrastructure - AMSI

The Adaptive Multiscale Simulation Infrastructure (AMSI) offers a comprehensive hierarchy of capabilities supporting the implementation of multimodel simulations on massively parallel HPC systems. With user-level support for dynamic runtime workflow management and simulation-level versatility, AMSI facilitates real-time algorithms backed by minimal overhead and robust coding practices. This framework caters to engineers, mathematicians, and computer scientists at various educational levels, currently focusing on multiscale soft-tissue mechanics, including macroscale finite element analysis and microscale RVE simulations.
