FlexPDE 7

FlexPDE not only passes a translation to some other processing package. In fact, FlexPDE is designed to be the package that other applications call for processing.

What is FlexPDE 7?

Imagine being able to type your system of partial differential equations, add a description of the problem domain, and instantly convert this problem specification into a sophisticated finite element model, including:

  • One, two, or three spatial dimensions
  • Automatic mesh construction
  • Dependent time, steady state, or autovalues
  • Flexible integrated graphic output
  • Adaptive mesh dynamic refinement
  • Dynamic timestep control
  • Nonlinear equation solver
  • Unlimited equation complexity
  • Unlimited number of simultaneous equations
  • Multiple Equation Sets
  • Complex, vector, and matrix variables and equations
  • Regionally Inactive Variables
  • Arbitrary moving mesh of Lagrange / Eulerian
  • Export capability for third-party views
  • Multithreading support for multi-core processors
  • CAD surface mesh import installation
  • Parameter optimizer

Adaptive Mesh Refinement

FlexPDE continuously monitors solution accuracy and adapts finite element mesh to address these high-error areas.

You don't need a dense mesh throughout the domain, because FlexPDE will find the areas that need it and put it there. FlexPDE adapts the mesh in front of the wave.

Lagrange/Arbitrary Euleriana Mobile Mesh

FlexPDE allows the definition of mesh motion equations and applies an Arrangerary Lagrange/Eulerian (ALE) formulation.

This allows for several optional behaviors:

  • By locking the mesh at fluid speed, you can create a fully Lagrangeano model.
  • You can define a relaxed mesh within moving boundaries to maintain the integrity of the mesh.
  • By omitting the moving equations of the mesh, you can perform a fully Eulerian computation.

In any case, FlexPDE automatically corrects the PDE system to represent mesh movement.

System requirements:

  • 32-bit versions of FlexPDE will perform equally well on 32-bit and 64-bit operating systems.
  • 64-bit versions of FlexPDE require a 64-bit computer, such as AMD64 or Intel Xeon or Pentium with EM64T extensions.

Windows platform-specific:

  • In Windows XP and 32-bit Vista, the addressable memory limit is 2 GB.
  • For 64-bit versions of Windows, the addressable memory limit for 32-bit FlexPDE is 4 GB.
  • The memory addressing capability for 64-bit FlexPDE is effectively unlimited.
