 ### Goals
 
 As a first approach to the structural solver in SU2, this tutorial will cover the solution of linear elastic problems. This tutorial will guide you through the basic commands for structural analysis, including:

  3. SU2 will print the residual of the linear solver, and the simulation will finish after one iteration.
  4. Files containing the results will be written upon exiting SU2. The flow solution can be visualized in ParaView (.vtk) or Tecplot (.dat for ASCII).
