Hi, Everyone.
I would like to read the data stored in the file called like restart_flow_*****.dat, which contain all the data of the each mesh point. Is there some good ways to output these data and make them be organised in python? Thanks very much. |

You'll need the SU2 mesh as well to know where the data is. Why not use the paraview data instead and load that in python? with pyvista you can basically do:
Code:
mesh = pv.read("output.vtk") cpos = mesh.plot() |

Thanks for reply. The reason that I use python to read data is that I want to extract the times series data from an unsteady simulation, which will take a lot of time for importing every data file into tecplot or paraview and then export. I think loading the binary file directly using the loop will be more convenient, I tried using Numpy but there are some decoding errors.

You can use paraview in batch mode using python scripts (https://www.paraview.org/Wiki/PvPython_and_PvBatch). If you have installed paraview, you will also have executables called pvpython and pvbatch.
The website gives you some instructions on how to generate a sample python file but you can also generate a python script example to perform any paraview operation from paraview. Open paraview, before performing any operations do "Tools->Start Trace". This will record all your operations into a python file. You can perform whatever operation you want for one file and then do "Stop Trace". This gives a python file which you can manipulate as you wish. |
