Hi all, I am facing the problem of exporting in MATLAB/excel the value of the pressure in a set of points in my fluid domain. I have an excel file with the (X,Y,Z) coordinates of the points in which I am interested in calculating the pressure.

I searched everywhere for a procedure for exporting the pressure values, but it doesn't seem to exist. Therefor I registered, hoping that somebody more experienced had already resolved this complicated problem.

Thank you, Lorenzo

This is very easy to do.

In the post processor you put a point object at your XYZ location and use file/export with the point object to export the data.

You can also get the data during a simulation by defining a monitor point at your XYZ locations. Then you can see the variables at those points as the simulation progresses in the solver manager.

Thank you for replying ghorrocks.

I knew that option, my problem is basically that I have to export the data in more than 100 points; this technique, inserting manually the (X,Y,Z) of each point, would be very time consuming. I thought that it could be possible to use an excel file containing the coordinates to speed up the procedure. Do you know if it is practicable?

If you want the points from the post processor you can do it in a session file. A point cloud might also help.

If you want to do it in the solver then write a script to generate the CCL, or use a perl gizmo in the CCL to generate then CCL.

No need for you to manually enter anything.
