Hi Filippo,

I hope the following answers will help you using the interactive capabilities of OM.

1. OMShell only generates the executable file including your model, equations, solvers and so on. This executable file can be used as non-interactive or interactive simulation runtime.
2. The generated file is similar to a server waiting for you requests.
3. Your GUI needs three communication components please see “OpenModelicaUsersGuide.pdf chapter 5.4.1 Network configuration Settings”.
By default your GUI should wait for “control operation replies” on 127.0.0.1:10500 and for “results” on 127.0.0.1:10502.

If you are receiving something but the strings are malformed your TCP/IP implementation to receive messages is not correctly implemented. If it is so and you are using C++ you can take a look at the existing source code of the interactive components from “trunk\\OpenModelica\c_runtime\interactive”
“socket_win.cpp”
“socket_unix.cpp”

For using the example client.cpp you need to copy the following files into VSC++ and to compile them:

Client.cpp
Socket.h
Socket.cpp
Socket_win.cpp
Socket_unix.cpp
