Summary: The volume of data produced by numerical simulations performed on high performance computers is becoming increasingly large. The visualization of these large post-generated volumes of data is currently a bottleneck for the realization of engineering and physics studies in industrial environments. In this context, Catalyst is a prototype in-situ visualization library developed by Kitware to help reduce the data post-treatment overhead. Additionally, Code_Saturne is a Computational Fluid Dynamics code developed by EDF, one of the largest electricity producers in Europe, for its large scale simulations. Both Catalyst and Code_Saturne are open-source software. In this chapter, we present a case study where Catalyst is coupled with Code_Saturne. We evaluate the feasibility and performance of this integration by running several use cases in one of our corporate supercomputers.For the entire collection see [Zbl 1304.54001].
