Hello

 

When I try to run a parallel function as part of FEKO solver I get the following error:

 

The following message from the master process (MYID= 0):

ERROR 3472: Unable to open the input file

 

The PC configuration is i7-7600 laptop with 16 GB RAM.

What can be the reason for this error?

 

Thanks.

    This error could happen if your model is on a network drive.

    Hello

     

    The model is located on a local drive.

    What can be other reasons for this error.

    Thanks

    It could also then be a rights issue.

    Try to save the model with a new name to e.g. the Temp folder.

    I could reproduce your error. It was accidentally and not exactly matches your configuration and I see your post is four years old now, but I still add my comment because it might help other users.

    In the case when calculating parallel on your local machine as set in the screenshot of the Ribbon:

    In the second screenshot e.g. in CADFEKO

    image

    in the first Menu -> "Settings" -> "Component launch options" -> second Tab "Feko Solver" you find the Option "Specify number of parallel processes". If it is on then you could enter, with the <configure> button, the name of your ->local PC<- and the maximum reasonable number of processes. But you could also leave the "Specify..." Option off when calculating locally then it seems that Feko decides on its own how many processes it will use. This works fine. However, if setting the Option "Specify number of parallel processes" to on and set the GUI Button "remote" to off with additionally another reachable ->remote machine<- existing as the first entry in the <configure> list and after that you then start a local calculation... with all this I can reproduce the "error 3472" which looks like this:

     

    The following message from the master process (MYID= 0):

    ERROR 3472: Unable to open the input file

     

    So it seems if you not switch completely with all settings from local to remote or back, FEKO will fail to start the calculation.
