For example, with the benchmark file "Parabolic/HT/SimpleSynthetics/PressureDiffusionTemperatureDiffusionStaggered.prj" instead of a list of values like ``` <property> <name>permeability</name> <type>Constant</type> <value>1.e-14 0 0 1.e-14</value> </property> ``` ``` <property> <name>permeability</name> <type>Constant</type> <value> <object[[i]]>1e-14</object[[i]]> <object[[i]]>0</object[[i]]> <object[[i]]>0</object[[i]]> <object[[i]]>1e-14</object[[i]]> </value> </property> ``` is written out.
