Answer:
The RWIND Simulation program organizes the data internally in the ParaView format. Since RWIND Simulation displays the results separately, the ParaView data are only stored in the working directory of the currently open RWIND Simulation entry.
The current working directory for temporary files is specified in the program options under the "Files and Directories" tab.
In the subfolder\~ RWIND_Simulation\Project\RF_Simul, the program saves the corresponding ParaView files with the results on the model and in the volume space around the model.
