Grozione New Member Lorenzo Curcio Join Date: Oct 2023 Posts: 1 Rep Power: 0	Hi everyone, I'm trying to extract data of the field in MATLAB and I need to know the coordinates for each of the data entries of p and U. I used writeCellCentres to output the cell centers, and at the beginning of the file it says 699582, which is the correct number, however there are 728858 points following. I should probably mention I've used snappyHexMesh to refine the domain. Also, maybe there's some other way of obtaining coordinates for the data, since I'm not even sure there is a correspondance between writeCellCentres and the fields p and U in the files. Maybe I'm missing something... thank you in advance! Lorenzo
