virtual void	disable_ALE ()
	This is an empty function that establishes a uniform interface for all (derived) elements that involve time-derivatives. Such elements are/should be implemented in ALE form to allow mesh motions. The additional expense associated with the computation of the mesh velocities is, of course, superfluous if the elements are used in problems in which the mesh is stationary. This function should therefore be overloaded in all derived elements that are formulated in ALE form to suppress the computation of the mesh velocities. The user disables the ALE functionality at his/her own risk! If the mesh does move after all, then the results will be wrong. Here we simply issue a warning message stating that the empty function has been called. More...

A MacroElement representation of the intrinsic coordinate parametrised by the local coordinate s is used if available.

Detailed Description

SolidFiniteElement class.

Solid elements are elements whose nodal positions are unknowns in the problem – their nodes are SolidNodes. In such elements, the nodes not only have a variable (Eulerian) but also a fixed (Lagrangian) position. The positional variables have their own local equation numbering scheme which is set up with

assign_solid_local_eqn_numbers ()

oomph::SolidFiniteElement::assign_solid_local_eqn_numbers

virtual void assign_solid_local_eqn_numbers(const bool &store_local_dof)

Assigns local equation numbers for the generic solid local equation numbering schemes....

Definition: elements.cc:6928

The derivatives of the ‘solid equations’ (i.e. the equations that determine the nodal positions) with respect to the nodal positions, required in the Jacobian matrix, are determined by finite differencing.

In the present form, the SolidFiniteElement represents a fully functional base class for ‘proper’ solid mechanics elements, but it can also be combined (via inheritance) with elements that solve additional equations. This is particularly useful in cases where the solid equations are merely used to update the nodal positions in a moving mesh problem, although this can prove costly in practice.

Fill in the residuals and Jacobian for the setup of an initial condition. The global equations are:

Use finite differences to calculate the Jacobian entries corresponding to the solid positions. This version assumes that the residuals vector has already been computed.

This function calculates the entries of Jacobian matrix, used in the Newton method, associated with the elastic problem in which the nodal position is a variable. It does this using finite differences, rather than an analytical formulation, so can be done in total generality.

inlinevirtual

In a SolidFiniteElement, the "global" intrinsic coordinate of the element when viewed as part of a compound geometric object (a Mesh) is, by default, the Lagrangian coordinate Note the assumption here is that we are always using isoparameteric elements in which the lagrangian coordinate is interpolated by the same shape functions as the eulerian coordinate.

Reimplemented from oomph::FiniteElement.

Reimplemented in oomph::SolidFaceElement.

◆ Lagrangian_dimension

unsigned oomph::SolidFiniteElement::Lagrangian_dimension

The Lagrangian dimension of the nodes stored in the element, / i.e. the number of Lagrangian coordinates.

◆ Multiplier_fct_pt

Pointer to function that computes the "multiplier" for the inertia terms in the consistent determination of the initial conditions for Newmark timestepping.

◆ Nnodal_lagrangian_type

unsigned oomph::SolidFiniteElement::Nnodal_lagrangian_type

private

The number of coordinate types requried to intepolate the Lagrangian coordinates in the element. For Lagrange elements it is 1 (the default). It must be over-ridden by using the set_nlagrangian_type() function in the constructors of elements that use generalised coordinate, e.g. for 1D Hermite elements Nnodal_position_types =2.

◆ Solve_for_consistent_newmark_accel_flag

bool oomph::SolidFiniteElement::Solve_for_consistent_newmark_accel_flag

protected

Flag to indicate which system of equations to solve when assigning initial conditions for time-dependent problems. If true, solve for the history value that corresponds to the acceleration in the Newmark scheme by demanding that the PDE is satisifed at the initial time. In this case the Jacobian is replaced by the mass matrix.
