// 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.

// vector
//  You can't define vector or tensor equations.  equationReader only works

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

//  To simplify an equation, you can create your own additional equations.
//  equationReader will find and evaluate them on-the-fly when needed. This
//  only works in dictionaries that are data sources to the equationReader.

//  Any amount of white space is okay.  Use a backslash to break a line.  The
//  equation can use +, -, *, /, and any functions I could find available to
//  scalar or dimensioned scalar.  Use the pow(a,b) instead of a^b.  Use
