nodalArray¶

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.

Parameters¶

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)

Example¶

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