Dear all Flow 3D experts

Now I am creating a very large long storage model with the length is 6000m , the widths is 100 m and the depth is 50 m with mesh size is 20m. My question is my model is normal? because it creates a very extraordinary result file size, it's 255 GB !! I'am very shocked with this size file.. . I am sorry because my question is ll bit out of Flow 3D core skill..

My best Regards,

Roy

No, that's not normal. Check your Output tab. Have you put numbers in any of the output interval boxes: restart, selected, or history? Those numbers are in seconds. If you put in small numbers you'll have very many outputs, and this will fill up your disk.

If you delete the numbers (blanks), FLOW-3D defaults to: restart output every 1/10th of the simulation time, selected & history outputs every 1/100th. This will produces an output file that might be up to 2 GB if you have a very very fine mesh, but you do not.

Once you have done that, check your mesh carefully to make sure you don't accidentally have billions of cells. You should have <=12 million for a desktop, and preferably <<1 million for a fast model.

I think the problem is in your output interval.
