    It's easier to mesh arbitrary shapes with first-order triangles. There are fairly simple,
    closed-form expressions for the element matrices with first order triangles, whereas things can be
    messier with higher-order elements. It's easier to formulate the algorithm for nonlinear problems
    with first-order triangles.
