ESPRESO API for ParaView Catalyst to perform In situ Analysis

Project reference: 1513

The main goal of this project is to develop a workflow for parallel “In situ” analysis using ESPRESO solver and ParaView Catalyst. During the stay the student will cooperate directly with developers of the ESPRESO library to implement the API for ‘”In situ” visualization of the transient finite element analysis using ParaView Catalyst.

The downside of the parallel machines is the enormous amounts of data that need to be saved and analyzed to determine the results of the simulation. The growth of IO capabilities has not kept up with the growth of processing power in supercomputers. Such coarse temporal sampling of transient analysis makes it difficult to notice some complex behavior. To address this issue, ParaView will be used to integrate concurrent analysis and visualization directly into ESPRESO code.
