Hello guys,

I yust wanted to have a look at your program, to start getting an understanding of how things work.
Going through the manual, I had some errors, here is the first which I am not able to solve myself:

I copied the files in the "Manual for Dummies" into the directory, where OpenFlower is lying and started with

"./OpenFlower example.flw"
it pastes:

System composed of 1 Equations: eqn1
- Mesh file          : geometry.msh
Finished reading 4 frontiers.

>>> In file MeshGmsh.cpp[196] <<<
User forgot to define frontier number 3

The mesh was created using gmsh. It seems, gmsh is a newer version which is using a different syntax, so I erased the first three lines:

$MeshFormat
2 0 8
$EndMeshFormat

and changed $Nodes to $NOD, $Elements to $ELM...

According to the reported error, on frontier is not defined. The last lines in the geo-file are (and I think they are the frontiers):

Volume (1) = {1000001};
//inlet_1
Physical Surface(124) = {29};
//inlet_2
Physical Surface(125) = {45};
//outlet
Physical Surface(126) = {65};
//walls
Physical Surface(128) = {57,61,70,13,69,33,41,49,53,37,41};
//volume
Physical Volume (127) = {1};

Help would be appreciated.
