1a. you can subtract an object of type SmoothIndicatorSphere3D from an object of type AnalyticalIdentity3D since they are both derived from the class AnalyticalF3D. You can find the respective inheritance diagram (AnalyticalF3D inheritance graph) in our doxygen. Please take a closer look here first for any questions regarding related problems.
1b. As phi is supposed to be defined between -1 and 1, the SmoothIndicatorSphere3D (ranging from 0 to 1) needs to be subtracted twice.
2. Any quantity can be transformed between lattice and physical units anytime by using the conversion factors in our UnitConverter. Those you can find in the UnitConverter log at the start of your simulation or by calling them like getConversionFactorLength(). Plenty of quantities can already directly be calculated by respective calls (UnitConverter functions). In case your quantity is not part of it, just check its dimensions and use the provided conversion factors to convert it in the same manner it is done in the UnitConverter.
