The porousZones method porousZones::ddt() mirrors the normal fvm::ddt()
method, but accounts for the effective volume of the cells.
An example dictionary entry:
@verbatim

note "some catalyst";
coordinateSystem system_10;
porosity 0.809;
intensity 0.001; // optional: default 1% turbulence
mixingLength 0.0001; // optional: default 1mm mixingLength
printCoeffs yes; // optional: feedback for the user
