How to turn off 3D data writing and save 2D slices?

xuegy · October 27, 2016, 17:49

Hello all,

Now I'm having a problem. The mesh size is about 60 million and I can't store 3D data at all. However I do need 2D slices of velocity and vorticity for every 0.05s. So here are the problems:
1.how can I turn off the 3D data output in controlDict?
2.how to compute and store 2D slices during running? Since there's no 3D data in the disk I can't use postProcessing.

Thanks.

1. Large write intervals. Or alternatively the purgeWrite option (safer in case of crashes). It's documented in the user manual.
2. functionObjects (plane or cuttingPlane). You can find a lot of examples online if you search for this keyword.
