3.2.2. Create Model Input File

The file blk3cellOct.inp defines the model (conductivity/active). The user specifies the locations, dimensions and values for a set of blocks. All undefined cells within the mesh are set to the background value. The format for this file is as follows:

Line #

Parameter

Description

1

Octree Mesh

path to octree mesh

2

Out Model Name

output model name

3

\(\sigma_b\)

background conductivity/susceptibility

4

\(N\)

number of blocks

5

\(x_1^{(1)} \;\; x_2^{(1)} \;\; y_1^{(1)} \;\; y_2^{(1)} \;\; z_1^{(1)} \;\; z_2^{(1)} \;\; m^{(1)}\)

Block 1

6

\(x_1^{(2)} \;\; x_2^{(2)} \;\; y_1^{(2)} \;\; y_2^{(2)} \;\; z_1^{(2)} \;\; z_2^{(2)} \;\; m^{(2)}\)

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/susceptibility value.
