problem with import mesh to openfoam and pached
 

hi friend
i use the salome to create geometry and meshed.i created group in geometry and mesh part.
picture


now i copy unv file to folder in tutorials/incompressible and then add 0 and system file from cavity folder and change the boundaryField like below

FoamFile
{
version 2.0;
format ascii;
class volScalarField;
object p;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

dimensions [0 2 -2 0 0 0 0];

internalField uniform 0;

boundaryField
{
train
{
type zeroGradient;
}

inlet
{

}

outlet
{
type fixedValue;
value uniform 0;
}

topbottom
{

}

frontback
{
type empty;
