When you look at the HDR file that is created for the turbulence, what does it think the size of the domain is in all three directions? In the BC-tangential directions, it should be 2 + 3.dx, where dx is the mesh spacing of the data that you are using to generate the turbulence. In the direction normal to the BC (usually z), the file should think the domain is 2 + dx. Aside from that, there should be a shift of dx/2 and dy/2 in the data you see coming in because the incoming data starts as cell-centered but is treated by the interpolator algorithm as node-centered. This shift should be "periodically-correct", in that the original source data was padded with periodic filling, but it will be shifted in both tangential directions the same way. If you don't want this behavior, you'll need to fix things in many places unfortunately. |

Following this discussion (AMReX-Codes/amrex#3775), I am trying to map the flow field from one PeleC simulation to another. The simulation domain from where the data is interpolated to the inlet uses periodicity in z but has EB in other direction (a channel flow for e.g.). May I confirm that turbInflow should work for this scenario?
