Help post! I'm having problems with rocky. I do fluent and rocky coupling calculations, after the particle enters the inlet, it passes through the entire watershed, but it stops at outlet, it can't pass through, and I wonder how to solve it. If you have encountered similar problems and solved it, hope to get your help, thank you very much!

Check what geometry is present in Rocky. Unless you're using SPH or have set something special you only really need the surfaces that represent walls or other boundaries that particles don't pass through. Tutorials should be available in Learning fairly soon, but I don't yet have any additional details.

I do have some problems, I'm doing a coupling calculation of rocky and fluent, and import fluent data into rocky through workbench.  But Rocky recognizes Fluent's watershed geometry as a wall, and once the particles enter the watershed, they can't get out.  I'm distressed.

OK, I do suggest not using Workbench. Open Rocky from the Start menu. In Rocky's geometry you should see Fluent's boundaries, delete all interior surfaces and (in this case) the outlet. We are adding a Rocky course to the AIS (Learning) system, so it will be easier to learn shortly.
