SysSimX Package#

syssimx - A Python framework for heterogeneous system co-simulation.

syssimx provides a unified interface for coupling heterogeneous simulation models including:

FMU Components: Functional Mock-up Units (FMI 2.0 Co-Simulation)
FEM Components: Finite Element Method solvers (NGSolve)
OpenSim Components: Musculoskeletal biomechanics models

Key Features:

Graph-based execution engine with automatic dependency analysis
Algebraic loop detection and iterative solving (IJCSA algorithm)
Hybrid co-simulation with event detection and superdense time
Multiple master algorithms: Jacobi, Gauss-Seidel, Hybrid

Example

>>> from syssimx import System, Connection
>>> from syssimx.components import FMUComponent
>>>
>>> # Create system and add components
>>> system = System(name="MySystem")
>>> pendulum = FMUComponent("Pendulum", fmu_path="Pendulum.fmu")
>>> system.add_component(pendulum)
>>>
>>> # Initialize and run
>>> system.initialize(t0=0.0)
>>> system.run(t0=0.0, tf=10.0, dt=0.01)
