Hello,
I am trying to perform cyclone simulation (steady, single phase) using available LRR model. As my knowledge in openfoam is quite limited I am not able to know what exactly the mentioned error suggests.

Different dimensions for =
dimensions : [0 2 -1 0 0 0 0] = [0 4 -3 0 0 0 0]

From function bool Foam::dimensionSet:perator=(const Foam::dimensionSet&) const
in file dimensionSet/dimensionSet.C at line 171.

I would be very much thankful for any suggestions.

I am very inexperienced with OpenFOAM but I did have this error when I was trying to move a case between solvers that used different units for pressure and phi. Maybe you could compare your unit definitions in your /0 folder to ones from a tutorial to make sure they're consistent?

Hi,

as Surgeron said, you mixed files and units. Check out the units in your time folder 0/ to be correct. One of the simplest ways is to copy a tutorial of the solver you want to use and adjust it to your needs.

Thank you for your suggestions... I will try to do as you both have said and get back to you with the details (Probably tomorrow).

Regards,
Mohak.

Hi everyone,

I am trying to implement turbulent integral Length scale in my code

PHP Code:

integralL = pow(turbulence->k(),3/2)/dissip; 


This is the error when I solved a test case using a newly compiled solver.

PHP Code:

smoothSolver:  Solving for k, Initial residual = 0.0396987, Final residual = 2.03498e-11, No Iterations 4
bounding k, min: -6.26895e-08 max: 3e-05 average: 6.72389e-08
[1] 
[1] 
[1] --> FOAM FATAL ERROR: 
[1] Different dimensions for =
     dimensions : [0 1 0 0 0 0 0] = [0 0 1 0 0 0 0]

[1] 
[1]     From function bool Foam::dimensionSet::operator=(const Foam::dimensionSet&) const
[1]     in file dimensionSet/dimensionSet.C at line 171. 


I have declared a new variable in code as follows

PHP Code:

volScalarField integralL
         (
         IOobject
         (
                 "integralL",
                 runTime.timeName(),
                 mesh,
                 IOobject::NO_READ,
                 IOobject::AUTO_WRITE
         ),
         mesh,
         dimensionSet(0, 1, 0, 0, 0,0,0),
         "zeroGradient"
         ); 


Could anyone direct me to find the cause of this error? I have checked units of all declared variable thoroughlly.

I had this kind of problem when I tried running different solvers on the same Case like potentialFoam and simpleFoam.

The solution was quite easy, I just had to delete the phi-file.

Your phi-field will be calculated from your velocity field anyway before the first iteration even starts.
