Scaling boundary conditions
I have a case with non-circular inlets on which I needed to specify fully developed flow. To do so, I extruded the inlets beyond the entry length, and ran a case for each inlet to convergence. I then used the mapFields utility to map the solved velocity for the inlets onto the real case.
I would now like to scale the fully developed flow, say from 1 liter per minute to 2 liters per minute. Is there an easy way to scale my boundary conditions? My 0/U file looks like this right now: Code:

Well, I ended up doing the following:
1) Run the simulation one time step with the controlDict switched to ascii mode 2) Use find-replace in 'vim' to reduce the boundary conditions to a three-column data file 3) Use 'awk' to multiply the data in each column by a constant 4) Use 'vim' to recompose the boundary conditions as desired It's a slow solution but it worked for me. Any further ideas for the future are appreciated. Thanks all. |
