WARNING: Region for fix oneway does not exist (../fix_oneway.cpp:84)

Dear All,

I would like to make use of “fix oneway” command to make one directional water motion. Could anybody let me know what the following WARNING message means?

fix posdir water oneway 1 right z
fix 3 water addforce 0.0 0.0 0.1
WARNING: Region for fix oneway does not exist (…/fix_oneway.cpp:84)

Thanks in advance

MajiD

The “right” argument is the ID of a region. Did you define

such a region?
