3.2.1. Create Model Input File

The executable blk3cell.exe is used to construct models comprised of a set of rectangular blocks. The user specifies the locations, dimensions and values for a set of blocks within an input file. All undefined cells within the mesh are set to the background value. The format for the input file is as follows:

Line #	Parameter	Description
1	\(\sigma_b\)	background conductivity/chargeability
2	\(N\)	number of blocks
3	\(x_1^{(1)} \;\; x_2^{(1)} \;\; y_1^{(1)} \;\; y_2^{(1)} \;\; z_1^{(1)} \;\; z_2^{(1)} \;\; m^{(1)}\)	Block 1
4	\(x_1^{(2)} \;\; x_2^{(2)} \;\; y_1^{(2)} \;\; y_2^{(2)} \;\; z_1^{(2)} \;\; z_2^{(2)} \;\; m^{(2)}\)	Block 2
\(\vdots\)	\(\vdots\)	\(\vdots\)
	\(x_1^{(N)} \;\; x_2^{(N)} \;\; y_1^{(N)} \;\; y_2^{(N)} \;\; z_1^{(N)} \;\; z_2^{(N)} \;\; m^{(N)}\)	Block N

where superscript \((i)\) for \(i=1,2,...,N\) refers to a particular block. \(x_1,x_2,y_1,y_2,z_1\) and \(z_2\) define the nodes of each block and \(m\) defines conductivity/chargeability value. Below is an input file example for a conductive and a resistive block within a homogeneous background.
