A nodalArray is a distributed array. This means during parallel runs the array is distributed across the different MPI domains. The nodalArray knows how to synchronize domain boundaries.


numComponents (integer)
Defines the number of components in the distributed array. Solving the Euler equations requires 5 variables per grid point so in this case numComponents=5.
useEpetraVector (boolean)
Use an Epetra compatible version of the nodal component array. Required if the data structured is used as an input/output vector for implicitMultiUpdater (1d, 2d, 3d)


<DataStruct q>
  kind = nodalArray
  onGrid = domain
  numComponents = 18
