Hi,
I am new to openFoam and at the moment I am running conjugate heat transfer using chtMultiRegionFoam . However, while I was running the function, I got an error in my limitU and the error can be presented as follows.

Unknown fvModel limitVelocity

Valid fvModels are:

23
(
accelerationSource
actuationDiskSource
buoyancyEnergy
buoyancyForce
coded
effectivenessHeatExchangerSource
explicitPorositySource
heatSource
heatTransfer
interRegionExplicitPorositySource
interRegionHeatTransfer
isotropicDamping
massSource
phaseLimitStabilisation
radialActuationDiskSource
radiation
rotorDisk
semiImplicitSource
sixDoFAccelerationSource
solidEquilibriumEnergySource
solidificationMeltingSource
verticalDamping
volumeFractionSource
)


file: /home/thamasha/OpenFOAM/thamasha-10/run/tutorials/incompressible/icoFoam/engine/system/air/fvOptions/limitU from line 29 to line 32.

From function static Foam::autoPtr<Foam::fvModel> Foam::fvModel::New(const Foam::word&, const Foam::dictionary&, const Foam::fvMesh&)
in file cfdTools/general/fvModels/fvModel.C at line 117
.



my limitU is in air/fvOptions/limitU is as follows.


limitU
{
type limitVelocity;
active yes;
selectionMode all;
max 100;
}



Therefore, could you please help me to solve this error.

Hello,

It seems you are using OpenFOAM-10, from the OpenFOAM foundation branch (openfoam.org, not to be mistaken with the OpenCFD branch, openfoam.com)

The foundation branch has reworked fvOptions into fvModels and fvConstraints. (more about this here: https://cfd.direct/openfoam/free-sof...s-constraints/)

With this new design, limiting functions such as limitPressure or limitTemperature are defined in fvConstraints rather than fvModels. In addition, it seems limitVelocity has been deprecated and replaced by limitMag: https://github.com/OpenFOAM/OpenFOAM...Mag/limitMag.H

Cheers,
Yann
