Define and exchange global data not accociated to a mesh.
Updated 18 Apr 24
Global data is not natively supported, but there is a simple workaround.
Every solver defines a mesh with a single vertex at (0,0,0)
and uses it to read/write data.
<data:scalar name="GlobalData" />
<mesh name="GlobalA" dimensions="3">
<use-data name="GlobalData" />
</mesh>
<mesh name="GlobalB" dimensions="3">
<use-data name="GlobalData" />
</mesh>
<participant name="A" >
<provide-mesh name="GlobalMeshA" />
<write-data mesh="GlobalMeshA" name="GlobalData" />
</participant>
<participant name="B" >
<provide-mesh name="GlobalMeshB" />
<receive-mesh name="GlobalMeshA" />
<read-data mesh="GlobalMeshB" name="GlobalData" />
<mapping:nearest-neighbor constraint="consistent" direction="read" from="GlobalMeshA" to="GlobalMeshB"/>
</participant>
