[solver-elements-tri{-mg-porder}]

Parameterises the triangular elements, or if -mg-porder is suffixed the triangular elements at multi-p level order, with

1. soln-pts — location of the solution points in a triangular element:

   alpha-opt | williams-shunn

2. quad-deg — degree of quadrature rule for anti-aliasing in a triangular element:

   int

3. quad-pts — name of quadrature rule for anti-aliasing in a triangular element:

   williams-shunn | witherden-vincent

Example:

[solver-elements-tri]
soln-pts = williams-shunn
quad-deg = 10
quad-pts = williams-shunn
