| 20 | ! Description: |
|---|
| 21 | ! ------------ |
|---|
| 22 | ! Calculates the reflection of particles from vertical walls. |
|---|
| 23 | ! Routine developed by Jin Zhang (2006-2007) |
|---|
| 24 | ! To do: Code structure for finding the t_index values and for checking the |
|---|
| 25 | ! reflection conditions is basically the same for all four cases, so it |
|---|
| 26 | ! should be possible to further simplify/shorten it. |
|---|
| 27 | ! THIS ROUTINE HAS NOT BEEN TESTED FOR OCEAN RUNS SO FAR! (see offset_ocean_*) |
