Dear All,


I am new to this forum and a new user of OpenFOAM. I have carried out a transient two-dimensional OpenFOAM simulation. I have the results for different time instants in different folders.


Now, I would like to extract data (velocity components and pressure) from a small specified portion of the computational domain for each time instant. Preferably, I would like to have the data in a file in the following format (for each time step):
x y u v p


where,

1st column: x-coordinate of the domain
2nd column: y-coordinate of the domain
3rd column: x-component of velocity at the location (x,y)

4th column: y-component of velocity at the location (x,y)
5th column: pressure at the location (x,y)


By portion, I do not mean a line or a point. By portion, I mean a small specified 2D domain of the full computational domain. Please see the attached image.



I would be grateful if you let me know how to extract the data of the specified 2D domain.



Thank you for your time.

Hi, I am wondering if you managed to do that.
Looking forward to hearing from you.
Best Regards
