Detailed Description

Base class establishing common interfaces and functions for all Navier-Stokes-like fluid interface elements. Namely, elements that represent either a free surface or an interface between two fluids that have distinct momentum-like equation for each velocity component.

Helper function to calculate the additional contributions to the resisuals and Jacobian that arise from specific node update strategies. This is called within the integration loop over the element (for efficiency) and therefore requires a fairly large number of input parameters:

  • the velocity shape functions and their derivatives w.r.t. the local coordinates
  • the surface gradient and divergence of the velocity shape functions
  • The local and Eulerian coordinates,
  • the outer unit normal,
  • the integration weight from the integration scheme
  • the Jacobian of the mapping between the local and global coordinates along the element. (Note that in the axisymmmetric case this includes the r term)!

Compute the surface gradient and surface divergence operators given the shape functions, derivatives, tangent vectors and position. All derivatives and tangent vectors should be formed with respect to the local coordinates.

Return the jacobian of the surface, as well as the dpsidS, and dpsidS_div objects.

This is the only function that needs to be overloaded to specify different geometries.

In order to compute the surface gradient of a scalar function one needs only compute the sum over the nodes of dpsidS(l,i) * nodal_value(l,scalar_index) To compute the surface divergence of a vector quantity one computes a sum over nodes and coordinate directions dpsidS_div(l,i) * nodal_value(l,vector_index[i]) In Cartesian cordinates the two surface derivatives are the same, but in Axisymmetric coordinates they are not!
