Hi Su,
well i have cyclic conditions for the inlet/outlet,symmetry plane bottom and three electrode patches with psi = 1/-1,alternating and fixed walls having a zero gradient.

how do i get to compile the code to suit my case?do i simply omit the temporal terms?

thanks in advance

Hi davey
you got a uniform field with laplaceFoam solver?

Hi Su,
yes,i do have a uniform field but i used the icofoam solver and commented out all the pressure and velocity terms ,whiles adding my laplace equation to it.seems to be working fine.will keep you posted on any mishaps which might crop up.

thanks
davey

To make a object auto writing, one have to register it using regIOobject.

try dimensionedField or use the internalField() of volScalarField

volScalarField temp
(
IOobject
(
"temp",
mesh.time().timeName(),
mesh,
IOobject::NO_READ,
IOobject::AUTO_WRITE
),
mesh
dimensionedScalar("zero", dimensionSet(0,0,0,0,0,0,0), 0.0),
zeroGradientFvPatchField<scalar>::typeName
)

scalarField &sf=temp.internalField();
sf=....

Hi su_junwei
I have a question! what does exactly the last zero in
dimensionedScalar("zero", dimensionSet(0,0,0,0,0,0,0), 0.0),
refers to?
