Dear all,

I want to run a simulation of a 2-D rayleigh-taylor instability case using interFoam. I have a heavy liquid (gamma=1) lying on the top of light liquid (gamma=0). In blockMeshDict, I set the left and right boundaries as cyclic. I set the initial gamma field using funkySetFields utility. The command is:

funkySetFields . RH1-cyclic -time 0 -field gamma -expression "1.0" -condition "pos().y>=0" -keepPatches

so the interface of both fluids is at y = 0 (at bottom boundary y = -0.1, at top y = 0.1)

However, I ended up having gamma=0.5 at left & right boundaries, as shown below.


Any idea how I can make the boundary values similar to the internal values?

Thanks a lot

solved the problem.

Cyclic boundaries should've been set as a single patch in blockMeshDict. So my problem had nothing to do with funkySetFields.
