# Journal - late at work 1:30 - 11:15 Lively EnergySim Demo for BP2013H1 & BP2013H1 - 11:15 Lively EnergySim Demo for Robert - Remarks: - we need "Units" for the End-user / Domain expert - can we see which SimPart changes other SimParts - trace it statically? Or why not dynamically? - other (Non-JavaScript) representations for the simulation
