#### MeshLocalBlockDirection

Section Execution::Optimization
Type integer

Determines the direction in which the dimensions are chosen to compute the blocked index for sorting the mesh points (see MeshLocalBlockSize). The default is increase_with_dimensions, corresponding to xyz ordering in 3D.

Options:

• increase_with_dimension:
The fastest changing index is in the first dimension, i.e., in 3D this corresponds to ordering in xyz directions.
• decrease_with_dimension:
The fastest changing index is in the last dimension, i.e., in 3D this corresponds to ordering in zyx directions.
