Description: Another derivative of the original SEDSIM, completely rewritten from scratch. It uses finite differences (in addition to the original particle-cell method) to speed up steady flow calculations. It also incorporates compaction algorithms. A general description has been published. Technical information Supported platforms: Windows Programming language: C_plus Model was developed started from: 2001 and was finished in 2006 To what degree will the model become available: Not Current license type: -- Memory requirements: 2GB Typical run time: 20 minutes Input / Output description Input parameters: Initial topography.
