What is PAMGEN useful for?

PAMGEN is useful for providing a parallel unstructured finite-element analysis code with a huge mesh. Top

How many elements can PAMGEN generate?

The number of elements PAMGEN can generate is limited by the size of a 32 bit integer (just above two billion). Top

Does PAMGEN scale well?

PAMGEN performs no internal inter-processor communication and so scales very well. Top

What kinds of elements can PAMGEN generate?

4 node quads in 2D and 8 node hexes in 3D. Top

Does PAMGEN perform any communication within its routines?

No. Top

What kinds of domain decomposition does PAMGEN provide.

PAMGEN provides several decomposition options. The most useful is a simple bisection strategy that slices the mesh in different topological directions. This strategy works best when the number of processors has many prime factors. A user defined slicing strategy allows control which topological direction are sliced. A random decomposition method is provided as a stress test for analysis codes. Top
