Hi,

could

ofile.writeln("NT=",lpModel.NT.solutionValue);

help ?

For instance

/*********************************************
 * OPL 12.8.0.0 Model
 * Author: AlexFleischer
 * Creation Date: Feb 5, 2018 at 3:39:20 PM
 *********************************************/
 dvar int NT;
 
 subject to
 {
 NT==2;
 }
 
 main{
 
var noUB=1;
 
//thisOplModel.settings.mainEndEnabled = true;
var ofile = new IloOplOutputFile("result2A_Com.txt");
 
 
 
//for (no=1;no<=noUB ;no++) {
//var lpConfig = new IloOplRunConfiguration("ster.mod", a+oper+c+room+c+no+b);
//var lpModel = lpConfig.oplModel;
var lpModel=thisOplModel;
//lpConfig.cplex.tilim = 10;
 
var obj;
lpModel.generate();//start time
 
var Starttime = new Date();
cplex.solve();
//lpConfig.cplex.solve();//end time
var Endtime = new Date();
 
//obj = lpConfig.cplex.getObjValue();
obj = cplex.getObjValue();
//var totalTime = Enclosedtime.getTime()- Starttime.getTime();
var totalTime=1;
//writeln("solnTime:", totalTime, " milisecs with obj ", obj);
ofile.writeln( " solnTime:", totalTime, " milisecs with obj ", obj);
ofile.writeln("NT=",lpModel.NT.solutionValue);
ofile.close();
 
 
 
//lpConfig.end();
 
//}
}

gives

 

solnTime:1 milisecs with obj 0
NT=2

in the output file
