Dear Olaf, In the meantime I checked the cpropepshell 1.01 interfase and it works pretty well for the selected exit conditions. I had only a small = trouble with the output data, which did not appear fully displayed, but this = can be solved by saving the results on the Note Block or by printing. By = the way, would it not be more meaningful to have as additional input = option, for exit conditions, the subsonic area ratio, as cpropep-web allows, = instead of two supersonic area ratios giving both the same results? Again thank you for your contribution which I appreciate very much and = which will be, no doubt, very useful for practical use and educational = training. Best regards and hoping to hear from you and our colleagues from the Rocketworkbench, Gunterio Heineken Buenos Aires, Argentina. =20 Send Rocketworkbench-devel mailing list submissions to roc...@li...

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=20 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...

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!
