Hello Vishal,
Is there any chance that you have opened this file with a windows editor? If so, try to do a "dos2unix" on it.

For the rest of the forum: can anyone tell me how it sould be discretized the following scalar equation?

where a, b, and c are scalars.
It seems that

fvScalarMatrix Eqn1(
fvm::div(a*fvc::grad(b)+a*b*fvc::grad(c))
);

is not an acceptable syntax.

Hi All,

As I had already posted before.. I would like to know more about how exactly PhiEqn.relax() and Phi.relax works. I know former is implicit and it relaxes the matrix and the latter just does it explicitly..but how exactly these are done in openfoam... .What is the advantage of one over the other and hown exactly one should choose between them??

Kindly offer your suggestions..

hi dear openFoam former
im going to solve a linear equation set in openFoam
AB=C ( A ,C are vectors and B is a tensor )
how can i manage this structure in openFoam? , i would like to use openFoam iterative solver directly
actually i have two vectors (A,C) and i'd like to find transformation tensor (B)
any help?
