Reply To: Extract velocity, pressure, and density data on lattices without interpolation

[achodankar]

Hello Julius,
Your feedback has been of great help to me. Thank you. Without using interpolation techniques(analytical functors & Blockreduction techniques), how I can store the velocity data from functors in a csv file. What would be the syntax for it? My coding background is weak for advanced C++ like functors. In the vtmwriter, I can view the results in Paraview, but for plotting my data, I would need the raw data in the form of csv files. I have been saving the data in csv files using interpolation methods in the past.
In regard to the cell method, how would the syntax be to extract the velocity/pressure/density values?(as you mentioned computeU and computeRho)?

Thank you.

Your sincerely

Abhijeet C.
