interIsoFoam crashes with nOuterCorrectors > 1

Hello,

when using interIsoFoam (version OpenFOAM-plus develop-prerelease) with nOutercorrectors larger than 1, the solver crashes with the following error message:

--> FOAM FATAL ERROR: previous iteration field IOobject: volScalarField alpha.water readOpt: 0 writeOpt: 0 globalObject: 0 "/home/heinri8/OpenFOAM/OpenFOAM-plus/tutorials/multiphase/interIsoFoam/damBreak/0"

not stored. Use field.storePrevIter() at start of iteration.

To reproduce this simply take the dambreak tutorial case and change nOuterCorrectors from 1 to 2 and start the Allrun script.

I assume there is a typo in the alphaEqn.H file on line 14. It states:

alpha1.prevIter();

It should probably be as following:

alpha.storePrevIter();

since the previous iteration is actually called later in the file on line 23.

Regards

Martin
