| void | set_contact_angle (double *const &angle_pt, const bool &strong=true) |
| Set a pointer to the desired contact angle. Optional boolean (defaults to true) chooses strong imposition via hijacking (true) or weak imposition via addition to momentum equation (false). The default strong imposition is appropriate for static contact angle problems. More... | |

| Empty helper function to calculate the additional contributions arising from the node update strategy to the Jacobian within the integration loop. This will be overloaded by elements that require contributions to their underlying equations from boundary integrals. The shape functions, their derivatives w.r.t. to the local coordinates, the unit normal and integral weight are passed in so that they do not have to be recalculated. More... | |
