Detailed Description

template<class ELEMENT>
class oomph::SpineLineMarangoniFluidInterfaceElement< ELEMENT >

Spine-based Marangoni surface tension elements that add a linear dependence on temperature to the surface tension, which decreases with increasing temperature. In addition, this element adds a flux contribution to the advection-diffusion equation to represent heat loss at the free surface. This introduces the Biot number.
