The basic calculation for converged nozzle has been implemented. The diffuser and confuser had been implemented before. We will continue to work for this program.
CFxD (update, September 18, 2020)
After a long thought we decide to develop CAD engine ourselves to avoid a dependence on 3rd party. Now, we are busy with selection module as the mathematical way is not convenient. So, we are trying to use OpenGL features.
CFxD (update, May 1, 2020)
We tried all month to move to CAD engine Open Cascade. Unfortunately, it seems that it is not possible as we want to have a direct access to the key features. So, we are still thinking if we need to use a third-side engine to accelerate our development.
GasDynCalc (update 02.02.2020)
We got some progress in GasDynCalc. The GUI and main strategy are defined. Some parts have been already implemented. We will continue to work on it. Below there is a GUI of pre-alfa version.

GTECalc (update 01.10.2020)
We updated manual. The installer for Windows has been added. Now, it can be installed as a usual Windows program. The updated program (ver. 1.0.1) is here.
GasDynCalc
We started to develop a new code to calculate pipes, valves, measurements elements, etc. connected in one network. It will be able to use for designing pipelines, experimental test cells, HVAC, etc.
GTECalc (update 06.19.2019)
We finished alpha version of GTECalc. The code has been verified with university code. There is an integrated help and separate manual in pdf format. It is free to use and download. The program is here.
GTECalc (update 04.21.2019)
We verified the calculation of turbojet engine/turbojet engine with afterburner with university student code. The results are slightly similar.
GTECalc (update 04.15.2019)
We finished the implementation of input variables verification. We are starting to validate jet engine calculation.
GTECalc (update 04.09.2019)
Gas dynamic functions have been implemented. We decided to integrate a new class to check all input parameters. Hopefully, it will not be long. The first structure was only main program. Now it is changing to
main program <-> gdf (gas dynamic functions), enthalpy (enthalpy calculation), inlet (inlet calculation), isa (atmosphere input calculation) and inputcheck (input parameters validation).
