- -SymX is a C++ library for **symbolic differentiation** with automatic **code generation**, **compilation** and **evaluation**. -Write complex mathematical expressions concisely, differentiate them arbitrarily, and let SymX evaluate them on your data structures — including global gradient and Hessian assembly. - -SymX targets **non-linear optimization pipelines** typical of **FEM solvers**, but it can be used for any application that needs JIT compiled math. -It uses a **stencil-based** perspective: expressions are defined per _element_ and evaluated over a discretization. -SymX is the core engine of [STARK](https://github.com/InteractiveComputerGraphics/stark), a simulation framework for FEM elasticity, shells, rigid bodies, and frictional contact. - -Here is an overview of the SymX pipeline for FEM elasticity simulation (see [Docs](https://interactivecomputergraphics.github.io/symx/diagram.html) for a detailed diagram). - -The goal is to reduce **time-to-solution**. -In research, the bottleneck is often the time between an idea and a trustworthy result. -SymX lets you quickly iterate while avoiding sinking time in **manual differentiation**, **testing derivatives**, **manual optimization**, **stack-indexed evaluation loops**, **parallelism/SIMD** and more. -You can develop complex solvers with great performance in a **fraction of the time and code footprint**, which quickly compounds productivity. - -## Applications where SymX was used -Here a list of simulations solved using SymX, corresponding to public research listed in [Research Using SymX](README.md#research-using-symx): -* Linear and high-order FEM for elasticity -* Linear and high-order shell mechanics -* Constrained rigid body systems -* IPC frictional contact in and across mechanical systems -* Dynamic and quasistatic simulation -* Volumetric and membrane micropolar materials -* Volumetric and membrane strain limiting and viscoelasticity -* Magnetism -* Differentiable shell mechanics -* Adjoint method (diff sim) for quasistatics - -The following gallery shows some of such results (see [Docs](https://interactivecomputergraphics.github.io/symx/examples.html) for example videos and images). - -## Features -- **Powerful symbolics:** Arithmetic, trig, sqrt/pow, min/max/abs, branching; arbitrary nested differentiation; automatic CSE. -- **Fast processing:** Expression building, differentiation and C++ code generation take milliseconds, scaling well to high-order FEM and shell models. -- **Fast evaluation:** Generated C++ with optional AVX2/SIMD for batched multi-element evaluation. -- **Parallel execution:** OpenMP-parallelized loops with optional graph coloring for concurrent evaluation. -- **Incremental compilation:** Generated code is cached on disk; unchanged expressions skip differentiation and compilation. -- **Zero-overhead abstraction:** Definition code (lambdas, dynamic loops, containers) runs only during expression building; emitted binaries are fully specialized. This allows for very expressive compositions that are concise and powerful (e.g. high-order FEM). -- **Layered API:** Three entry points — single expression, expression + discretization loop, full second-order global solve. -- **Bring your own data:** Views into user arrays; no data format imposed on your discretization. -- **FEM integrator:** Symbolic FEM integrator with Tet4, Hex8, Hex27 and other element types for 3D mechanics. -- **Global assembly:** Concurrent and fast global assembly of gradients and Hessians from composable potential definitions; multiple coupled DoF sets supported. -- **Newton's method:** Robust second-order solver with line search; customizable convergence and callbacks. -- **Projection to PD:** Newton, [Projected Newton](https://dl.acm.org/doi/10.1145/1073368.1073394), [Project-on-Demand](https://arxiv.org/abs/2311.14526) and [Progressively Projected Newton](https://arxiv.org/abs/2505.21013), with clamping or [mirroring](https://dl.acm.org/doi/10.1145/3641519.3657433). - - -## Hello World -Here are "hello world" examples for the lowest and highest entry points of SymX. - -### Low-level: compile a single expression - -```cpp -Workspace sws; -Scalar x = sws.make_scalar(); - -Scalar dsinx_dx = diff(sin(x), x); - -Compiled compiled({ dsinx_dx }, "hello_world", "../codegen"); -compiled.set(x, 0.0); - -View result = compiled.run(); -std::cout << "dsinx_dx(0.0) = " << result[0] << std::endl; -``` - -It defines an expression containing derivatives. -SymX writes the generated source, compiles it with your system compiler and loads the shared object. -Then a numerical value is set for the symbol `x`, the function is executed and the result printed. - -### High-level: Non-linear Newton solve from potential definitions - -```cpp -spGlobalPotential G = GlobalPotential::create();
