		+	a proposal for volume output box. With these specifications, the box to be less than 14 GB in memory requirement to fit into a single node. By skipping second grid,
		+
		+	10125 NX = x model dimension in nodes
		+	5000 NY = y model dimension in nodes
		+	1060 NZ = z model dimension in nodes
		+
		+	75 NPX = number of procs in the x direction
		+	40 NPY = number of procs in the Y direction
		+	10 NPZ = number of procs in the Z direction
		+
		+
		+	Volume output range should be this way:
		+
		+	1001 NBGX2 = first x node to contain receivers
		+	9000 NEDX2 = last x node to contain receivers
		+	2 NSKPX2 = skip of nodes containing x receivers
		+	501 NBGY2 = first y node to contain receivers
		+	4500 NEDY2 = last y node to contain receivers
		+	2 NSKPY2 = skip of nodes containing y receivers
		+	1 NBGZ2 = first z node to contain receivers
		+	900 NEDZ2 = last z node to contain receivers
		+	2 NSKPZ2 = skip of nodes containing z receivers
		+
		+	80 NTISKP2 = time skip of seismograms (every nth step)
		+
		+	This would generate 4000x2000x450x4bytes --> 13.4GB each component and step, that is 39 TB size outputs in total.
