SHORT SUMMARY

The goal of this work was to integrate in situ possibilities into the general-purpose code-coupling library PDI [1]. This is done using the simulation code Alya as an example. Here, an open design is taken into account to later create possibilities to extend this to other simulation codes, that are using PDI.

Here, an in transit solution was chosen to separate the simulation as much as possible from the analysis and visualization. To implement this, ADIOS2 is used for data transport. However, to prevent too strong a commitment to one tool, SENSEI is interposed between simulation and ADIOS2 as well as in the in-transit endpoint between ADIOS2 and the visualization software. This allows a user who wants a different solution to easily implement it. However, the visualization with ParaView Catalyst was chosen as default for the time being.
