The Windows version of this thermal cycle modeling tool is only marginally functional at this time; however, the DOS tool on which it is based is fully functional, but not interactive; so there's still a lot of work to be done. In some cases you can still run the old solver. The core of this program is SCRAP (Steam Cycle Rankine Analysis Program), which I developed in 1983 and presented in 1990 as a technical paper entitled, "Steam Cycle Analysis Specifically for the Micro Computer," at the ASME Winter Annual Meeting in Houston, Texas. SCRAP was the first fully-functional thermodynamic cycle modeling program that could handle a complex system on a microcomputer.

Currently, CyclePro will import a GateCycle™ or PEPSE™ model directly from an RPT or JOB file, respectively, both of which are plain text. CyclePro will position the components graphically based on the text. You can move them around and save the file. This will preserve where you put the items as comments in the plain text files. CyclePro will also read and create DXF files, which may be the cycle drawing, thermodynamic properties, or nothing to do with cycles at all, like the 57 Chevy pictured below (which is actually 3D). You can edit the graphics and save it back out as DXF or copy it onto the clipboard. CyclePro only partially solves the system at this time, unless it's a SCRAP input file, which will be solved completely. There are 9 GateCycle, 19 PEPSE, and 16 SCRAP examples included. CyclePro will completely analyze GateCycle macros, down to the operational level (plus, minus, times, divide). CyclePro will also graph GateCycle™ tables, such at the generator curves shown above that are inside 4X1CC.RPT.
I want CyclePro to become open source and am looking for a community to make that happen. What I'm not interested in, is developing a tool that will only run on LINUX or will only compile with gcc, which seems to be the case with many other open source projects. Please contact me if you have any ideas.
