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, and approximate dynamic characteristics using reduced-order models.
Coupled Thermal-Stress Analysis
Analyze mechanical behavior under coupled thermal and mechanical loads.
Electrostatics and Magnetostatics
Solve Maxwell’s equations modeling electrostatic and magnetostatic problems.
Solve second-order linear and nonlinear PDEs for stationary, time-dependent, and eigenvalue problems.
