3  * \example elasticity.cpp
4
5  The example shows how to solve the linear elastic problem. An example can read
6  file with temperature field, then thermal stresses are included.
7
8  What example can do:
9  - take into account temperature field, i.e. calculate thermal stresses and
10 deformation
11  - stationary and time depend field is considered
12  - take into account gravitational body forces
13  - take in account fluid pressure
14  - can work with higher order geometry definition
15  - works on distributed meshes
16  - multi-grid solver where each grid level is approximation order level
17  - each mesh block can have different material parameters and approximation
18 order
19
20 See example how code can be used \cite jordi:2017,
21  \image html SquelaDamExampleByJordi.png "Example what you can do with this
22 code. Analysis of the arch dam of Susqueda, located in Catalonia (Spain)"

24
25  This is an example of application code; it does not show how elements are
26 implemented. Example presents how to:
28  - set-up problem
29  - run finite elements on the problem
30  - assemble matrices and vectors
31  - solve the linear system of equations
32  - save results
33
34
35  If you like to see how to implement finite elements, material, are other parts
36 of the code, look here;
37  - Hooke material, see \ref Hooke
38  - Thermal-stress assembly, see \ref ThermalElement
39  - Body forces element, see \ref BodyForceConstantField
40  - Fluid pressure element, see \ref FluidPressure
41  - The general implementation of an element for arbitrary Lagrangian-Eulerian
42  formulation for a nonlinear elastic problem is here \ref
43  NonlinearElasticElement. Here we limit ourselves to Hooke equation and fix
44  mesh, so the problem becomes linear. Not that elastic element is implemented
45  with automatic differentiation.
