What is MultiScale Design?
Combining computational tools Multiscale, Multidimension Multiresolution
Minimum requirement: 2 tools + dynamic link

Why MultiScale Design?
Real life simulation problems are complex (=multiscale, multi dimension) Single scale modeling tools are well in use
Accuracy is proven
It is time to take the next logicical step

Boiler (thermal power) as a component in Grid
Demands from Grid
Demand is cyclic Market is volatile Green power must be used when
available – Weather dependent makes demand & market much
more volatile
Nuclear power is BASE Other sources are SWING or
PEAK
Realities of Boiler
Boilers are designed for continuous running Start up’s wear the equipment Fast start up’s wear equipment fast Idling equipment consumes energy
and resource, creates emissions
Share of maintenance cost becomes unpredictable
