Dear Foamers,

I have a mesh of a flow-over-a-2D-bump case that is constructed in GMSH and however I encountered the following error when I want to convert it to OpenFOAM format by gmshToFoam.

Does anyone know why the foam warning is happening? Also, for "Problem: Patch dummy starts at 35611", I checked the file but it is indeed in incremental order.

I will be glad if anyone can help .

I am using Gmsh-2.10.1 and OpenFOAM-4.1
