Re: NEC-LIST: Re: Large model in GNEC from command line (AlexandreKampouris)

Of course, do not forget the basic fact that you need the NEC executable to
be compiled for at least 10,000 segments, as well as having 2GB RAM for
double precision or 1GB for single.

NEC had source-coded tag limit of 10000, which could be problematic. See

I don't know anything about this particular binary, from the message
I would guess that the RTL DLL or some other module couldn't be
located at runtime.

You could perhaps change the current directory in Matlab to the one
containing the EXE before launching it, or see whether some
environment variable could be set to define a path to all the
required modules. In that case you would launch a batch file rather
than the EXE directly.
