Hi

if i run an optimization 2 times, second time get a similar message:

logfile: cannot access file because another process uses it

what should i do? how can i close logfile or env?

some part of my code:

GRBEnv env = GRBEnv(true);
env.set("LogFile", logfile);
try {
env.start();
}
catch (...) {
return (GRBModel*)0;
}
static GRBModel model = GRBModel(env);

 

thanks
