User Units

The system of units used for input and output values can be set at compile time to one of three different conventions. See section Compiler Directives. Two of them are the standard mks and cgs (SI) units. The third one offered is the native "LSP user units," which is the default condition. The latter has been found to be very practical for running simulations. All physical quantities mentioned in this manual are in user units, unless otherwise specified.
