i am working on a project in which i generated mesh using salome and converted it into openfoam format but after converting it i found that i have to use setFields utility to set two separate fluids in their positions anyone plz help me in doing that.... i would be grateful to you

Hello,

this shouldn't be difficult. Just take a setField from a tutorial and edit it with your wished positions.

boxToCell   
    {
    box (0.5 -3.7 -0.75) (22 -2 15);
        fieldValues
        (
            volScalarFieldValue alpha.water 1
        );
    }

Just keep in mind that the coordinates are (xmin ymin zmin) (xmax ymax zmax).

Best regards,
Mike

Hi,

I have a case with 2 phases as i attached in a picture. I have meshed it in ICEMCFD and converted the model to OpenFOAM.

Now i have to define field values using setFieldsDict but the problem is how find the box values (like box (0.5 -3.7 -0.75) (22 -2 15) from converted model is the question.

I am new to OpenFOAM. Could you please help me?

Regards,
Sam

Your system of coordinates should be the same as in ICEM, just keep in mind that OpenFOAM works in meters, maybe you have to transfer the units.
The box values are the coordinates of the starting and ending point of the diagonal line of the box.
So, you can either take the points from ICEM or you open your mesh in paraview, for example, and take the coordinates from there.

Hi ,

Could you please suggest me how to know the co-ordinated of the point in paraview ?

You can use the Ruler under Sources to get your coordinates.

Hi,

Your suggestion worked for me. But once I do setFields and check in paraview then paraview automatically closing and giveing a message killed.

What would be the solution for the problem ?

Thank you all i have solved problem using blockMesh

I have create a field for temperature.

but I do not know where to write the value for the field.

Im new in openfoam stuff.

Can you tell me, how u solved the problem?

Hey,

I and trying to use setField on a background cuboid which I created using Salome. you can find the file in https://drive.google.com/file/d/10BI...ew?usp=sharing. I want to know the dimensions of the cuboid and coordinate of the edges which I created so that I can apply setFields to make it part water and part air. Can anyone suggest me how to obtain it?

Thank you in advance for the help

Kind regards

Hello

Everyone

I want to perform a simulation with interfoam and I need to define the setField (with a STL file)? How can I do it?

Thanks
