a problem of icemcfd in linux
 

I am using icemcfd v11SP1 in linux system. I am trying to export grid file from it. What I am doing is choose solver 'multiblock.info'. then 'write input', then I got the error message: running ICEM CFD/CAE Multi-block info Vers. 5.0.0, unrecognized arg. -b'.

what's that? anybody met the same problem? any idea? please

by the way, I can export grid file using icem in windows (the same steps)

many thanks
