Acoustics module does not work in parallel -FLUENT 6.0.20
Acoustic Model runs on Single CPU. However the same case doesn't run in parallel. The acoustic scheme file is available.
Acoustic Model in FLUENT-6.0.20 will not run on parallel if you read the case/data files first and then the scheme file. The model will only run in parallel if the scheme file is read first before reading the case/data files.
