faSurfaceStructureSolver:
- To compile the code, first load OpenFOAM-v2012 then execute the "Allwmake"
  script in the parent directory.
- This is by far not a mature solver, but is rather a cleaned-up snapshot of 
  the development.
- Some comments and so on might still be included that refer to older versions 
  and are deprecated. Also, some relicts might still be in the code from 
  dead-end developments.

testCaseFaSurfaceStructureSolver:
- All test cases presented in the paper are included, except for stationary
  test cases with grid densities 80 and 160.
- "Allrun" and "Allclean" are used for running and resetting to initial state
- "Allrun" loads an "Allrunconf*" file for a specific test case setup, see line 
  14 in "Allrun". The "Allrunconf*" files contain further case-specific
  comments. Test cases in the order as in the paper are:
  - Stationary membrane test case:  Allrunconf.ValidateSS.stationary
  - Transient membrane test case:   Allrunconf.ValidateSS.transient
  - Membrane Oscillation test case: Allrunconf.ValidateSS.oscillate
  - Coupled solver test case:       Allrunconf.ValidateFSI
- Example: Assume you want to run the oscillation test case for the first
  eigenmode with a time step size of 1/100 of the corresponding oscillation
  time scale:
  0. Load OpenFOAMv2012
  1. Alter line 14 in Allrun to load "Allrunconf.ValidateSS.oscillate"
  2. Alter line 19 in Allrunconf.ValidateSS.oscillate to "[...]="sin1""
  3. Alter line  6 in Allrunconf.ValidateSS.oscillate to 
     [...] bc <<< "scale=9;$one_cycle_time/100.0 [...]
  4. Alter line  5 in Allrunconf.ValidateSS.oscillate to "[...]=0.1414213"
  5. Run Allrun script in the testCaseFaSurfaceStructureSolver directory
- Results used in the paper are included in the file ResultData.ods. The values
  listed there should be reproduced by the simulations.
- At the current state, the deflection is hard-coded to Z direction (see file 
  0.init/pointDisplacement)
- The FSI cases omit the first few time steps (no coupling), due to the 
  pressure peak from sudden inflow change at the beginning, which would 
  overshadow most of the actual subsequent fluid-structure interaction
- The stand-alone surface structure validation cases use the FSI environment 
  and solver, but simply do not use the pressure field but the "dummyLoadField"
  as load field. So there is no real stand-alone surface structure solver.
  This implies a huge overhead, because the fluid field is also solved, but 
  is sufficient for validation.
