The ACS SASSI Version 2.3.0 baseline code has been extensively verified, tested, and used for seismic 3D soil-structure interaction models up to 20,000 nodes including up to 5,000 interaction nodes (using version 300M that is provided within installation kit). However, for 20,000 node or slightly larger-size SSI problems, the baseline code becomes numerically inefficient on regular PCs, since the analysis runtime and the disk storage go out of hand.

The ACS SASSI Version 2.3.0 fast-solver code, called Option FS, has been extensively verified, tested, and used for seismic 3D soil-structure interaction models up to 100,000 nodes including up to 10,000 interaction nodes. The fast-solver code is much more numerically efficient than the baseline code. On MS Windows PCs with 16-32 GB RAM, SSI problems with sizes up to 80,000 nodes including up to 8,000 interaction nodes were run highly efficiently using in-core solution algorithms. On larger memory capacity PCs with up to 192 GB RAM under Windows 7 OS we tested even larger-size problem problems with up to 13,500 interaction nodes.

The user of ACS SASSI should be aware that some analysis options including 2D structural models and the skin method for impedance evaluation were only briefly verified for few problems with relatively small size models.
