This code has the following syntax:
 * the prefix Variable specifies that the velocity is not a constant but a variable
 * the coordinate the velocity profile is based on is Coordinate 2, meaning Y
 * the velocity values are returned as Real (floating point value)
 * MATC is the prefix for the Elmer solver that the following code is a formula
 * tx is the variable in the formula
