The CBSFLOW software can optionally output data in either Tecplot or ParaView formats. CBSFLOW output is optimised for ParaView, which can be obtained here (external link). ParaView is an open-source, multi-platform data analysis and visualization application. ParaView users can quickly build visualizations to analyze their data using qualitative and quantitative techniques. The data exploration can be done interactively in 3D or programmatically using ParaView's batch processing capabilities.
The parallel CBSFLOW implementation requires a partitioned mesh, which can be undertaken with the provided CBSFLOW RA Partitioner. This partitioner utilises Scotch (external link) which is a software package and libraries for sequential and parallel graph partitioning, static mapping and clustering, sequential mesh and hypergraph partitioning, and sequential and parallel sparse matrix block ordering. The library must be pre-built (but can be installed via Ubuntu repository amongst others). Scotch is free/libre software licensed under CeCILL-C.
