I've picked away at the http://www.lotusfile...re_software.exe Engine Sim freeware on and off for a few years, mostly with no real purpose but to see "what if". It's been a while since I played with it, so I'm rusty again, but I can't seem to sort my self out of this.
Within the parametric / optimizer tool, if you have the cylinder in an available group, is an option to vary the bore and stroke while maintaining constant capacity. No matter how I've tried to load and approach it, I keep getting a "That option is not available" error. Is this because I'm running the freeware version (which I thought was only limited to a single cylinder model with 3 sensors and 3 actuators but otherwise fully functional) or because I've got something skewed in my model?
Edited for link - lesoft.co.uk no longer resolves.
