What is MultiScale Design?

Combining computational tools Multiscale, Multidimension Multiresolution

Minimum requirement: 2 tools + dynamic link

inputs outputs

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
