nreg [none, real]



nreg is the number of regions for which presi(ireg) , tempi(ireg) , tkei(ireg) , scli(ireg) , er(ireg) , and mfrac(isp, ireg) are read in.  



In general, these regions match those of nregions, but one could, for example have a single-region duct, with regions 2 and 3 that do not really exist, but are used to supply inlet and outlet conditions for flow through the duct.  In this example, nregions would = 1, but nreg would = 3.
