i just finish install openFOAM 1.6 on Ubuntu 9.10

when i follow user guide to run example "cavity"

the step " blockMesh"

i enter the dictionary "tutorials/incompressible/icoFoam/cavity/constant/polyMesh"

i key the command "blockMesh"

the i got a message

/***************** Message *********************/

Cannot find file "points" in directory "constant/polyMesh"

From function Time::findInstance(const fileName&, const word&, const IOobject::readOption)

Greetings nt31921a,

You should have ran blockMesh from inside the folder "tutorials/incompressible/icoFoam/cavity/" and not "tutorials/incompressible/icoFoam/cavity/constant/polyMesh/".

The user guide just points out where the blockMeshDict file is, not that you should run it from there

Best regards,
Bruno
