FlexPDE 有限元素分析軟體

FlexPDE is a self-contained processing system that
analyzes your problem description
symbolically forms Galerkin finite element integrals, derivatives and dependencies
builds a coupling matrix and solves it
plots the results.

FlexPDE does not merely pass a translation on to some other package for processing. In fact, FlexPDE is designed to be the package other applications call for processing.

Imagine being able to type in your partial differential equations system, add a description of the problem domain, and instantly convert this problem specification into a sophisticated finite element model, including
One, two or three space dimensions
Automatic mesh construction
Time dependent, steady-state or eigenvalues.
Flexible integrated graphical output
Dynamic adaptive mesh refinement
Dynamic timestep control
Nonlinear equation solver
Unlimited equation complexity
Unlimited number of simultaneous equations
Multiple Equation Sets*
Complex, Vector and Array Variables and Equations*
Regionally Inactive Variables*
Arbitrary Lagrange/Eulerian moving mesh
Export capability for 3rd-party visualizations
Multithreading support for dual and quad core processors*
　

Here are some of the new features in version 6 :
Multithreading - Support for dual and quad core processors. Run multiple problems simultaneously or use up to 8 threads for parallel execution within a single problem.
Complex, Vector and Array Variables and Equations - Direct support of these data types simplifies equation construction.
Regionally Inactive Variables - Variables can be declared inactive in some regions and active in others.
Multiple Equation Sets - Splitting of equations into sets that are solved sequentially and alternately.
Additional Status Graphs - Updated graphical interface to include plots of cell/node number, error, convergence and timestep.
Internal Tabulation Facility - Build on-the-fly tables of computationally intensive parameters for more economical execution.
Arrays and Matrices - Extended support allows array and matrix operations for use in equations, graphics and domain construction.
Planes, Cylinders, Spheres - Simplified Construction of Planes, Cylinders and Spheres in 3D.
Stop and Restart Facility - Simplified facility for restarting a script after stopping.
Web-based Licensing - Move license from machine to machine with web actions. No dongle to loose!
