Dear Olaf, I was using your most welcomed cpropepShell interface. I found that it has more calculation options than Gpep, which allows only for shifting equilibrium performance evaluation. Your interface has similar options as Cpropep-web http://rocketworkbench.sourceforge.net/equil.phtml but allows calculations for systems with more than three components, which is a limitation of cpropep-web. I found that cpropepShell interface works well for adiabatic flame temperature and fixed pressure and temperature calculations , but I had trouble with exit pressure and area ratio imput data for frozen and shifting equilibrium conditions. In general for this calcultions, as Gpep and cpropep-web require, for a given chamber pressure, either exit pressure or supersonic area ratio are selected, but not both at the same time, since they are functionally related. CpropepShell interface requires input of both exit pressure and two? supersonic area ratios. The result is that we obtain incorrect exit parameters for the selected input data, which do not correspond either to the selected exit pressure nor to the area ratio, and the outprint never gives the input exit pressure back. Output values for chamber and throat sections are o.k. and identical to those obtained with Gpropep and cpropep-web interfaces. May be you can help to overcome this trouble. Thank you very much for your effort. Best regards and wishes. Gunterio Heineken CITEFA Buenos Aires, Argentina -----Mensaje original----- De: roc...@li...

Subject: [Rocketworkbench] GUI for Cpropep I have made a small application - nothing special really - that provides a graphical userinterface for cpropep under Windows. For those interested, it may be found at http://users.cybercity.dk/~dko7904/DARK/download/cpropepshell.zip The application need to be located in the same directory as cpropep.exe and cpropep.conf.

Note that there is another GUI for windows at http://www.msu.edu/user/asman called Gpep. I will put links for both application on the web page. Is the source code for your application available ? Thanks for your work.

I wasn't really aware of that, so maybe I could have spared the efford. However it was quite fun to do and I learned a couple of things during the process, so maybe the only drawback is that there are now two different interfaces for Windows and none for other platforms. > Is the source code for your application available ? In principle yes, but it is very sparsely commented (uncommented actually...) so I would like to add a few comments if source code is to be made public. Source code is written in Delphi - it could maybe be ported to Linux with some limited efford. > Thanks for your work. - Cpropep itself is the real achivement, so thanks for Your work Antoine!
