42 | ! Description: |
---|
43 | ! ------------ |
---|
44 | ! This is an EXAMPLE routine how to read NetCDF particle data output by PALM. |
---|
45 | ! As an example, the mean heigth and radius of all particles are calculated |
---|
46 | ! and output for each output time available on the file |
---|
47 | ! |
---|
48 | ! |
---|
49 | ! Any additonal analyzation requested has to be added by the user by following |
---|
50 | ! the steps given in this example! |
