There is a bug where the expansion ratio/nozzle exit diameter is not set correctly. Check the values if you get some weird thrust results. Another build will fix this in the next few days. -----Original Message----- From: Greg Deputy [mailto:greg at blastzone.com] Sent: Sunday, May 11, 2008 6:31 PM To: 'burnsimannounce at burnsim.com' Subject: Bugfix version release BurnSim version 3.0.89 has been released with the following changes: bugfix - max kn not working bugfix - zero nozzle throat error when clicking new sim button bugfix - unsaved file check when clicking new sim button updated reg so registered users can activate immediately The latest version can be downloaded from www.burnsim.com.
