I made the settings according to the user guide, but encountered the following issues，after editing the TXT file according to the help document, there is a "Please specify coupling approach: uncoupled/coupled." problem when reading the file. I am sure that there is no problem with the model input. Some files are as follows:

1

0.6

inject-wall

coupled extract-wall

discrete  Point-Direction ext-discrete

dynamic compressible

% x y z vx vy vz diameter cd

I assume both "inject-wall" and "extract-wall" exist and are adjacent to the fluid(s) volume(s).

yes, i am sure that "inject-wall" and "extract-wall" exist and both are adjacent to the fluid(s) volume(s)

I can't see anything obvious so have asked one of our second line team. That could take a few days depending on holidays & time zones as well as availability. If we've not responded by late Monday please bump the thread.

Having had the thread checked the format looks OK. Can you check if "Point-Direction" and "point-direction" makes a difference?  Are there any spaces or odd characters in the path name? Did you type the commands into a text editor or copy from the documentation? If the latter can you check for white space characters. 

The two points defined create a cylinder that is projected to the two surfaces (injection & extraction), I assume the axis this sets will hit those surfaces? That shouldn't be the issue here given the error seems to be earlier in the set up.
