It is very rare to obtain complete 3-D information in
the form of images of the microstructure of a material.
Most often this information is incomplete because the
resolution is inadequate, or is restricted to 2-D, via
some kind of micrograph, or is not available at all. In
the case of incomplete microstructural information,
electrical measurements are then used to try to check a
hypothesized microstructure, to see if it can account
for the measured elecbical response. But even when
complete microstructural information is available, if
the microstructure is random, then it is not possible to
analytically calculate the electricalal response of the
microstructure. The use of computer simulations both to
generate material shape and topology and numericalty
solve the electrical equations, is then required.
Computer simulations allow the use of more complex
hypotheses for the microstructure of a material, as the
electrical response can be accurately computed for a
wide range of microstructural shapes and topologies.
