Hello,

Hello,
I'd like to add some fields to the createProbes.H file, like vorticity, e.g. any field defined in applications/utilities. It does not work by just adding the lines #include "vorticity.C" Probe<volvectorfield> vorticityProbe(probeLocations, vorticity); because the file vorticity.C is not found. What link should I define ? or is it more complicated ? thanks ! mélanie |

there is a utili
hi melanie
there is a utility to find vorticity. look in page U-89 of users manual hope this helps kumar |
Thanks kumar,
I know how to
Thanks kumar,
I know how to find the vorticity utility. My question was about how to add the vorticity field (or another) in the createProbes.H file (oodles case), i.e. how to record the vorticity at a defined point during a transient simulation ? thanks. mélanie |
1. You must create vorticity a
1. You must create vorticity as a derived field in createFields.H (see the vorticity tool)
2. Then you add a vorticity probe entry in createProbes.H (oodles is a good example) 3. Make sure you update the vorticity field at least once per timestep. 4. Add a write entry for the vorticity probes to writeProbes.H |
Thanks Eugene,
I have created
Thanks Eugene,
I have created vorticity in the createFields.H as in the vorticity tool; no problems with createProbes.H nor with writeProbes.H, but when I compile (wmake), I have the error message: tzntgq@cfdlem04:~/OpenFOAM/OpenFOAM-1.2.1/applications/solvers/DNSandLES/oodles> wmake make: Nothing to be done for `allFiles'. make: `Make/linuxAMD64Gcc4Opt/dependencies' is up to date.

I eventually found my error; the #include "createFields.H" in createProbes.H was unnecessary and created a bug...
thanks again and please excuse me for being a beginner in C++... mélanie |
Hi,
I want to probe the walls
Hi,
I want to probe the wallshearstress and wallgradu for a few boundary points. I write the 'createProbes.H' and 'writeProbes.H' like 'oodles' model in openfoam 1-2-1 as following. But the probe results only include the first point, and not the others. Could you inform me how to deal with? createProbes.H: Info<< "Reading probeLocations\n" << endl; IOdictionary probeLocations ( IOobject ( "probeLocations", runTime.constant(), mesh, IOobject::MUST_READ, IOobject::NO_WRITE ) ); Info<< "Constructing probes\n" << endl; //Probe<volvectorfield> UProbe(probeLocations, U); //Probe<volscalarfield> pProbe(probeLocations, p); Probe<volvectorfield> wallShearStressProbe(probeLocations, wallShearStress); Probe<volvectorfield> wallGradUProbe(probeLocations, wallGradU); writeProbes.H: wallShearStressProbe.write(); wallGradUProbe.write(); |
