| 33 | ! Description: |
---|
| 34 | ! ------------ |
---|
| 35 | ! This is an EXAMPLE routine how to read NetCDF particle data output by PALM. |
---|
| 36 | ! As an example, the mean heigth and radius of all particles are calculated |
---|
| 37 | ! and output for each output time available on the file |
---|
| 38 | ! |
---|
| 39 | ! |
---|
| 40 | ! Any additonal analyzation requested has to be added by the user by following |
---|
| 41 | ! the steps given in this example! |
---|
