Thanks for your response. > The reduced basis code uses the FEMContext to define the quadrature rule. To vary the quadrature order that is used by the FEMContext you can either set the integer extra_quadrature_order in your System, or you can use the extra_quadrature_order argument to the FEMContext constructor. I suggest you refer to System and FEMContext for more info about this.
