    Hello Raviteja,

    Actually, this is not a cosimulation error but a license error. It seems that your license is not valable. As you see, problem is not araising when you try to connect to Matlab but before, when it tries to open Flux GUI.

    I think, best thing you can do is to contact to your local support team, they should be able to provide you a new license file or to fix the one you have already.

    Best regards.

    Hi,

    What version of both software are you using? Maybe it is a compatibility problem. Please, find attached the supported Matlab version for different Flux releases.

    If the problem persists, we will check the environment variables.

    Best regards.

    Hello Raviteja,

    This is probably the problem. Unfortunately, Flux 2019 has compatibility with Matlab versions from 2016b to 2018b, compatibility with 2019b version is not assured, as far as it has not been qualified.

    Best regards.

    Hello Raviteja,

    Sorry for this late answer, but I was thinking about this problem with the coupling and I have a question for you.

    Have you ever launched the file to activate the API and the parallel computation? It is placed in C:\Program Files\Altair\2019\flux\Flux\Bin\prg\win64\Active_Distributed_Computation_and_API.

    Launch this code is necessary in order to run any coupling with Matlab or Simulink.

    Best regards.

    hello Alejandro

     

    i have run the API also. still it does not show any change. the checked the license file and i am having matching physical addresses.  i created the environment variable also. i didn't make any  changes in altair license manager.
