Butterfly - Points not found in polyMesh

snappyhexmesh

#1

Hi,
I am trying to analyze an outdoor airflow I get this error while trying to use blockMesh:

1. Solution exception:
 --> snappyHexMesh Failed!
--> FOAM FATAL ERROR: 
Cannot find file "points" in directory "polyMesh" in times 0 down to constant

    From function Foam::word Foam::Time::findInstance(const Foam::fileName&, const Foam::word&, Foam::IOobject::readOption, const Foam::word&) const
    in file db/Time/findInstance.C at line 202.

FOAM exiting

is there a way to fix this?
any help would be appreciated…

Update: After playing for a while I found out that if I rescale the geometry to half of its size the wind tunnel works. Does butterfly(BF) have a height limit? BF could not create the case (blockMesh) for original geometry with 300 meters height. i was able to do the analysis through rescaling the geometry to half.
