Hi !
I was working on the Version OF1.7.1 under interFoam application, the problem when I installed the new version OF3.1, my example was walking on the old version no longer works on the new version, if you please help me?

Hi,

it is normal to have problems when you change the openfoam's version, a lot of things change from version to version.
Anyway, despite that, without more information it's imposible to help you out.

Usually the error printed on terminal contains a lot of information to solve the problem. Perhaps post it here.

Look up the interFoam tutorials in the newer OF version and check where your files are different. fvSchemes, fvSolution, transportProperties, controlDict, etc. It is normal that the syntax is changing between versions.
Maybe some boundary condition has been replaced or renamed.

Hi,

from the error printed it appears that on the "alpha.water" file, at the /0 folder, there's no 'object' entry on the line 14. Check the file, right under the header, it should look like this:

FoamFile
{
    version     2.0;
    format      ascii;
    class       volVectorField;
    location    "0";
    object      U;
}
