Fluent Output Data Question

fossu15a · March 27, 2009, 17:00

I have a grid which I have imported into Fluent. I want to export three "tables" of data from my mesh, velocity magnitude at a specified point, instantaneous centerline velocity (along a line of symmetry) and velocity profile of axial velocity at a specified point. Eventually I need to input this data into Matlab. I've tried exporting data in a ASCII format, but it is only returning the data point I've set. How can I extract this information?

Thank you in advance

hello
I'm not sure the answer I'll give you will be efficient , but, by using XY-plot, you can export some datas into text or xls files. For example, I use it to export temperatures along walls.

You just have to tick the Box " write to file" in the XY plot panel, and name the file. Don't forget to tick the " order points" , to keep the values ordered by x or y position.

Hope it will help you

regards

What I understood is, you are able to dump the data into ASCII file but then you need to structure them into specific way, is it right?

Yes I'm trying to output the data, but that format is only giving me one line of given information. I'm now trying to use a surface monitor at a point, but I can't seem to calculated the axial velocity at a given point.
