Hierarchical Engine for Large-scale Infrastructure Co-Simulation (HELICS)

FMI 2.0 implementation written in modern C++.

SIL Kit – Open-Source Library for Connecting Software-in-the-Loop Environments

A cross-platform C++20 3D library with Python bindings and the high-level API of three.js.

High-performance C++ multibody dynamics/physics library for simulating articulated biomechanical and mechanical systems like vehicles, robots, and the human skeleton.

A tasteful, minimal C++ base library.

A multithreaded discrete event simulation library in C, using POSIX pthreads for parallelized trials and replications, stackful asymmetric coroutines for concurrent simulated processes inside each thread, and optionally CUDA or other GP GPU parallelism for detailed model physics inside each coroutine.

G+Smo (pronounced gismo or gizmo) is a C++ library for isogeometric analysis (IGA). Geometry plus simulation modules aims at the seamless integration of Computer-aided Design (CAD) and Finite Element Analysis (FEA).
