Spatial Domain

In Spatial Domain the user defines the problem size, component by component. For each spatial coordinate there must be specified a minimum an maximum value. You will notice two elements with a Math children. Their values must be mathematical expressions using the limited AsciiMath syntax [1] (See asciiMath reference).

We may simply want to set \(x = 0\) for the minimum value for the region and \(x = 2 * \pi\) for the maximum value, for instance:

Notice that pi is an AsciiMath reserved word that translates to π.
