|
pdnMesh is a program that can solve 2D potential problems (Poisson Equation)
|
|
and eigenvalue problems (Helmholtz Equation) using the Finite Element Method.
|
|
Common applications occur in electromagnetics, heat flow and fluid dynamics.
|
|
It can solve problems using both Nodal Based Formulation and Edge Based
|
|
(Vector) Formulation.
|
|
The features of the program are as follows.
|
|
* Automatic mesh generation according to given boundaries.
|
|
* Adaptive and Interactive mesh refinement.
|
|
* Problem solution using Cholesky Decomposition or Conjugate Gradient
|
|
Method with sparse storage.
|
|
* Eigenvalue solution using LAPACK.
|
|
* (Optionally) Eigenvalue solution using QR iteration with shifts.
|
|
* Generating plots of contours, mesh and gradient on screen.
|
|
* Generating Encapsulated Postscript plots of countours and mesh.
|
|
* Generating a data file of the mesh to be used by other solvers.
|
|
* Can import DXF files generated by CAD programs.
|
|
* GUI is avaibale with glut and GTK/GTKGLExt. Needs OpenGL.
