    Hello, how do i convert from physical porosity into lattice units in the latest OLB version (1.8r0)? The user guide for 1.7 mentions the unit converter method: “Additionally, the class UnitConverter in src/core/units.h provides useful functions for conversion between physical and lattice values” but i cannot find any function like that in the current version.

    Thanks in advance.

    Hi,

    AFAIK, porosity is a scalar between 0 and 1, so you don’t need to convert it.

    Have a look at the porous media examples.

    Hi, okay thank you! I thought so too but the user guide made me question that, but turns out i was just confused.
