Integrated <strong>modeling</strong> in magnetic fusion<br />

Integrated <strong>modeling</strong>: self-consistent interaction <strong>of</strong> specialized codes<br />

to capture complex interplay <strong>of</strong> different physical processes<br />

Manual integration <strong>of</strong> different codes is a complicated endeavor<br />

Many integrated <strong>modeling</strong> s<strong>of</strong>twares have been developed<br />

(SWIM, ONETWO, CRONOS, TRANSP, CORSICA, ITM-IT, TASK, ...)<br />

Two main categories:<br />

1 Transport solver:<br />

• External components to calculate equilibrium, sources <strong>and</strong> fluxes<br />

• Tight coupling: Data exchange at memory level<br />

2 Workflow-manager:<br />

• Data “flows” through <strong>the</strong> components<br />

• Loose coupling: Data exchange through files
