Partial Differential Equation Toolbox
Solve partial differential equations using finite element analysis
Partial Differential Equation Toolbox™ provides functions for solving structural mechanics, heat transfer, and general partial differential equations (PDEs) using finite element analysis.
You can perform linear static analysis to compute deformation, stress, and strain. For modeling structural dynamics and vibration, the toolbox provides a direct time integration solver. You can analyze a component’s structural characteristics by performing modal analysis to find natural frequencies and mode shapes. You can model conduction-dominant heat transfer problems to calculate temperature distributions, heat fluxes, and heat flow rates through surfaces. You can perform electrostatic and magnetostatic analyses, and also solve other standard problems using custom PDEs.
Partial Differential Equation Toolbox lets you import 2D and 3D geometries from STL or mesh data. You can automatically generate meshes with triangular and tetrahedral elements. You can solve PDEs by using the finite element method, and postprocess results to explore and analyze them.
Linear Static Analysis
Compute displacement, stress, and strain under load and boundary conditions, and evaluate a component’s mechanical strength and behavior.
Modal and Frequency Response Analysis
Find natural frequencies and mode shapes to identify and prevent potential resonances, and simulate dynamic behavior of a structure using its frequency responses.
Compute displacement, velocity, acceleration, stress, and strain under time-varying loads.
Steady-State Thermal Analysis
Find temperature distributions and other thermal characteristics under constant thermal loads.
Transient Thermal Analysis
Find temperature distributions and other thermal characteristics under time-varying thermal loads.
Coupled Thermal-Stress Analysis
Analyze mechanical behavior under coupled thermal and mechanical loads.
Reconstruct 2D and 3D geometry from imported STL or mesh data, or create simple parameterized shapes using geometric primitives.
Generate finite element mesh using triangular elements in 2D and tetrahedral elements in 3D. Inspect and analyze mesh quality to assess accuracy of results.
Plot and Animate Solutions
Visualize models and solutions by creating plots and animations of geometry, mesh, results, and derived and interpolated quantities by leveraging powerful MATLAB graphics. Create multiple subplots and easily customize plot properties.
Create a typical FEA workflow in MATLAB – import or create geometries, generate mesh, define physics with load, boundary, and initial conditions, solve, and visualize results – all from one user interface.
- Automate FEA simulations by using MATLAB® language, execute simulations faster leveraging Parallel Computing Toolbox™,
- integrate with other MATLAB products such as Simscape™ Multibody™ to build an end-to-end workflow,
- share custom applications using MATLAB Compiler™ and App Designer as a standalone application or as a web app.
