Hallo,
is there any known bug in mergeMeshes? I've tried to merge two simple meshes. I've modified the boundary-file of the master-case like described here
http://www.cfd-online.com/Forums/ope...h-problem.html

This is the result from OpenFOAM 1.6 (the 'same' in 1.6.x, 1.5-dev shows 'segmentation fault' only):


// * * * * * * * * * * * * * * * * * * * * * * * * * * * * //
Master: "." "case-master"
mesh to add: "." "case-add"

Create Times
Reading master mesh for time = 0
Create mesh

Segmentation fault

-----------------------------------------------------------------------


Now I recompiled the 1.5-dev in Debug-Mode. This lead to the following output:

---------------------------------------------------
Master: "." "case-master"
mesh to add: "." "case-add"

Create Times
Reading master mesh for time = 0
Create mesh


start 2720 out of range 0 ... 2719

From function UList<T>::checkStart(const label)
in file /home/of15/OpenFOAM/OpenFOAM-1.5-dev/src/OpenFOAM/lnInclude/UListI.H at line 79.

FOAM aborting

Aborted
---------------------------------------------------

Face 2720 should be the first face in case-add.
the following is a snip of the boundary-file of case-master

--------------------------------------------
.
.
.
minZ-1 // case master - last patch
{
type patch;
nFaces 200;
startFace 2520;
}

maxX-2 // case add - first patch
{
type patch;
nFaces 80;
startFace 2720;
}
.
.
.
--------------------------------------------

any idea, whats wrong?


maybe there is 'only' a problem in my system or in my head ...

I hope, someone can help ... thanks in advance ...

greetings, Axel

Hello,
I am sorry, my fault ...
it is no bug in mergeMeshes ... now it is much more confortable, than I rememberd from earlier versions.

Two cases, one acts as master, the other as add case and simply performing

mergeMeshes . case-master . case-add

without any change in constant/polyMesh/boundary results in the merged mesh in the time 1 folder in the master-case.

That's all ... thanks to the programmers!!

Good night and greetings,

Axel
