Attached the snippet of error message poping out while running case on Sloshing dynamics. Solver used is interFoam. Please suggest further on this. Your help is much appreciated.

Hi Kazzy,

I hope you have already resolved ur issue. If not simply add the following lines in your constant/fvOptions file.
Code:
 19     alpha.water
 20     {
 21         nAlphaCorr      1;
 22         nAlphaSubCycles 3;
 23         cAlpha          1.5;
 24     }

Hello,

Thanks for responding to my query. However, I am still not able to run the solver using interFoam. Please check below error message:

Hi kazzy,

Based on the error info
HTML Code:
Size 38100 is not equal to the expected length 107400
it seems you are either
using a old mesh and new alpha (from setFields)
or
using a new mesh and old alpha (from setFields)


The easy way is to just execute
1) foamCleanPolyMesh
2) blockMesh (assuming you are generating your grid from blockMesh)
3) setField -time 0
and then proceed with your solver

FoamFile
{
format ascii;
class dictionary;
location "system";
object setFieldsDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

defaultFieldValues
(
volScalarFieldValue alpha.water.orig 1
);

regions

boxToCell
{
box (-1 -1 0 ) (1 1 0.453 ); //****Insert here coordinate of box that includes cells to refine****

fieldValues (volScalarFieldValue alpha.water.orig 1 ); //****Insert here name and value of field to set****
}
);


// ************************************************** *********************** //

Above is my setFieldsDict

Please check as I am getting same error message even after running your suggested scripts.

''Size 38100 is not equal to the expected length 15000''

Hi Kazzy,

I think the problem is somewhere else. I'm not sure if alpha.water.orig is the correct syntax for your case in the setFieldsDict
Code:
boxToCell
{
box (-1 -1 0 ) (1 1 0.453 ); //****Insert here coordinate of box that includes cells to refine****

fieldValues (volScalarFieldValue alpha.water.orig 1 ); //****Insert here name and value of field to set****
}

I just did a quick search within $FOAM_TUTORIALS and could NOT find a single entry for "alpha.water.orig". If I'm not wrong the correct one should be just alpha.water
