the code is listed below.
if i use at least one of the simmodel.end() , cplex.end(), the lefttmp array was freed. but if i do not use this method, the program will be out of memory.
how can i do to free the model's memory but keeps the array?
main

datasce2 = new IloOplDataElements();
datasce2.numm = 2;
optmodel.addDataSource(datasce2);
optmodel.addDataSource(datafile2);
optmodel.generate();
var numsa=Opl.card(optmodel.sitepro);
var numt=Opl.card(optmodel.nperiod);
var numall=numt*numsa;
var lefttmp= new Array(); //this memory was freed after calling simmodel.end() or cplex.end()
var lefttmpall= new Array();
