LIMS History

The history of this simulation package goes to early 90’s when Bruschke and Advani created the original program based on even older simulation (TIMS) by Advani and Tucker. The program would solve the infusion flow within shell like structure (2.5D) and with second and third release some rudimentary flow control (sequential injection) and approximate non-isothermal solver.

In 1996-7 the program was rewritten from scratch by the current authors to implement the much faster incremental solver1 and proper process controls. This became the version 4.0. The need for simulation engine to be controlled from other application lead to the version 4.1, which added the dll-controlled executable.

LIMS version 4.2. implemented simplified non-isothermal solver. This version was abandoned with growing requirements for fully three-dimensional simulation to deal with thick parts and distribution layers. These came – together with one-dimensional elements to model distribution lines and racetracking with the currently maintained version 5.0.

Several experimental versions were created to model flow in gravitational field, to improve the modeling of inlets and to provide full three-dimensional non-isothermal solver. Number of extensions were also added using the scripting engine. Most of these are described in Research Publications Using LIMS[PS1] .
