“The modelling of intake systems for Internal Combustion Engines (ICE) was previously done on mainframe computers based on the Acoustic Wave Finite Element (AWFE) assembly procedure with input by files in fixed format. These caused problems with preparation and validation of input, and also, economy and ease of processing. Thus, a software package applying the AWFE assembly procedure in a microcomputer was created. Modelling was simplified by assigning global node numbers to each wave pair instead of the global degree of freedom (dof) numbers assigned to each wave in the induction system. The software is interactive, menu driven, and user friendly. Accessible software functions allow the user to develop, retrieve, edit, modify, view, validate, store, or process an input file. Graphic capabilities provide a tool to depict the induction system of interest, and also, to plot output data. All prompted input is well defined on each screen and graphical illustrations are included for clarity during input of data for all AWFE elements. Error trapping and diagnostic functions were supplemented to the software based on a criterion for node duplication, connectivity, and general node requirements. Lastly, an instructions manual is accessible in the software for user training. Testing performed ascertained the reliability of the software and conformance with the fundamental AWFE modelling procedure” -- Abstract, page iii.
