Hi Foamer!

I am trying to do tutorial of cyclicACMI with OF2.3.x oscillatingInletACMI2D.
I can not set non-zero velocity on ACMI2_blockage.
fixedValue (0 0 0) is default setting. I want to set fixedValue (10 0 0) on the ACMI2_blockage of U.
But it didn't work well. it became fixedValue (0 0 0) as time progresses.
Somebody know how to fix it?

Regard,
kkk

Hi,
I encountered the same problem as you regarding cyclicACMIs and imposed non-zero velocities. Did you find a fix yet? I saw on the openfoam bug tracker that apparently the problem is not resolved yet. I would be very thankful for any help...

Hi
I checked openfoam bug tracker after a long interval. It seems to take more time to fix it. I tried to read the scripts about cyclicACMI, I don't think I can fix it by myself. Actually,there is no choice but to wait.

Hi

I found the other way to set non-zero velocity on blockage wall of cyclicACMI.
timeVaryingUniformFixedValue has to be used instead of fixedValue.
Actually,timeVaryingUniformFixedValue seemed to become obsolete in OF2.3.x.
But you can use it of OF1.7.1.
I attached "oscillatingInletACMI2D" being set timeVaryingUniformFixedValue on ACMI2_blockage of U.
I am very happy if this could help someone.
Plese don't forget wmake libso timeVaryingUniformFixedValue before running.

Regards,
kkk
