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

[syed]

Thank you Julius for your reply, and indeed I was looking for options available in OpenLB, like CSV class, to write the data.
And with “metadata” I meant the lattice point’s positions over which the density is defined.
I understand the segmentation fault would have been because of wrong indexing while using the functor.
Do you think the writing data for each lattice point and the lattice point position itself could be possible using the writeData function of the CSV class?
And I want to know where exactly the data is stored, like in what object?
