// scalar
// You can use any variables on single scalars. If a field is used, equation
// reader will take the value at cell index 0 unless you tell it otherwise.
// You can mix types, provided you give a valid component. This equation is
// for a scalar, so it ignores dimensions.
sOut "sA + dsB + vC.x + tA.yz";
// dimensionedScalar
// This equation will be evaluated twice: once for the scalar value, and once
// for the dimensionSet. If the dimensions don't match, it will fail. You
// can subscribe a dimensionSet. This will disable dimension-checking, and
// force the outcome to the dimensions you give it - this is shown for dsfOut.
dsOut "sqrt(sqr(vB.x) + sqr(vB.y) + sqr(vB.z))";
// dimenionedScalarField
// You can use any variables on fields. If single variables appear, they are
// assumed uniform throughout the field. If GeometricFields appear, the
// boundary field is ignored. If another field is given, its size must match.
// Index checking is slow, so it is only available in FULLDEBUG mode. In this
// equation, we define a dimensionSet. This forces the outcome to the
// prescribed dimension.
dsfOut [0 0 0 0 0 0 0] "V / C.x * t";
// volScalarField
// This is for a GeometricField. GeometricField equations are very picky
// about their source data. They can either use single-element sources, such
// as scalars, tensors, etc., or other GeometricFields. The GeometricFields
// must have the same sizes.

// at a time. To use a constant built-in to OpenFOAM, append _ to the name.
