1. While compiling paraview with a local version of Qt using

unable to calculate alignment for long double

real 15m19.591s
user 51m35.033s
sys 6m21.592s


WHY IS THIS ERROR "Unable to calculate alignment for long double is coming and how to reslove it??



2. In one case, i ignored this error and tried to simulate the cavity case using

cd $FOAM_RUN/tutorials/incompressible/icoFoam/cavity
blockMesh
icoFoam
paraFoam

then while opening paraview, it asks me

A reader for /home/cfd/OpenFoam/cfd-1.6/run/tutorials/incompressible/icoFoam/cavity/cavity.OpenFOAM could not be found. Please choose one:

Gaussian Cube Files
Raw (binary) files

MFIX Unstructured Grid Files
Fluent Case Files
Open Foam Files
Cosmology files


WHICH OPTION SHOULD I CHOOSE??

Sadly, the last time I had that problem or similar, I had to rebuild gcc 4.3.3. If you really want to rebuild gcc 4.3.3 that comes with OpenFOAM, here are the instructions for it: OpenFoam Installation in Redhat Enterprise linux 5 post #4

I think that for you to save time, it's best that you just get the latest ParaView 3.8.0 from here: http://www.paraview.org/paraview/res.../software.html

Or install the ParaView version available for your openSUSE using YaST, and then use this script: Alternative to paraFoam

Sadly, only starting ParaView 3.8.0 does a native OpenFOAM reader exist in ParaView that can read OpenFOAM 1.5 and above. The reader version available in versions prior to 3.8.0 can only open OpenFOAM cases from OpenFOAM 1.2 or something like that

So, either you can build ParaView with PV3FoamReader, or use any of the other solutions I've told you about.

Best regards,
Bruno

What is the possible solution for it??.....this command reconstructPar is working fine on cavity case in icoFoam but why not here in aachenBomb???

Is there anything in the folder processor0 inside aachenBomb? If not, that's why "No times selected" was shown.
Possibly, this happened because you didn't run decomposePar first.

I have run decomposePar before it and inside processor0, there are two folders named "0" and "constant"......


So what is the problem now??

That means that you haven't run the solver yet? I just tested reconstructPar and it will only reconstruct the folders that are yet to be reconstructed, and both processor0/0 and processor0/constant are folders that decomposePar created, thus there isn't anything left to reconstruct!

As for the solver, I believe that aachenBomb is a dieselFoam tutorial case. Have you executed dieselFoam using mpirun or foamJob?

Bruno
