Hi,
I'm trying to create a new volVectorField, but I want it uniform 0 when creating it. I think it's something like volVectorField myField ( IOobject ( "myField", runTime.timeName(), mesh, IOobject::NO_READ, IOobject::AUTO_WRITE ) uniform 0 ); I know it is made for p in interFOAM v1.5 (I work on v1.6 if it can help), but p is initialize with other existing volVectorFields. If anyone has an idea, it would be great, it's the last thing that doesn't work in my program and it's driving me crazy... I could also create and read an existing volVectorField and then multiply it by 0, but I think there must be a cleaner way to do it. Regards, Julien |

Maybe you can try to use mesh,scalar(0) instead of uniform 0 ?
But I think this is for a scalar field ... I don't know how this may work for a vector...

To start with, you have a volVectorField, so it won't take scalars.
Substitute uniform 0 for: mesh, Foam::vector(0,0,0) or mesh, dimenstionedVector("variableName", dimensionSet(0,0,0,0,0,0,0), Foam::vector(0,0,0)) substituting the for the relevant values in dimensionSet obviously.

Thank you both,
Laurence, you anticipated my next problem with dimensionedVector! Best Regards |

symmTensor:
Code:
volSymmTensorField Rsymm ( IOobject ( "Rsymm", location_phase_average, mesh, IOobject::NO_READ, IOobject::AUTO_WRITE ), mesh, dimensionedSymmTensor("R", dimVelocity * dimVelocity, symmTensor(0.0 ,0.0, 0.0, 0.0, 0.0, 0.0)) ); Code:
volTensorField R ( IOobject ( "R", location_phase_average, mesh, IOobject::NO_READ, IOobject::AUTO_WRITE ), mesh, dimensionedTensor("R", dimVelocity * dimVelocity, tensor(0.0 ,0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0)) ); |
