Examples with UnitImpl ucar.units_vcell.UnitImpl used on opensource projects

Example 1 with UnitImpl

use of ucar.units_vcell.UnitImpl in project vcell by virtualcell.

the class VCUnitTranslator method expandUcarCellML.

// time mult not included.
// first call: (1.0, 0, unit, new ArrayList(), transType)
// Problem: units override each other's mult/multiplier before getting to the level of derived unit.
// To avoid that, add a dimensionless unit for cases where
