Summary of Changes

!!!!!!----IMPORTANT NOTE----!!!!!!!
CHANGES INCLUDED IN THIS CODE MERGE REQUIRE ALL MEMBERS TO RE-COMPILE JETSTREAM AND ALL 3RD-PARTY SOFTWARE PACKAGES USING VERSION 15.0.6 OF THE INTEL FORTRAN COMPILER

(DON'T FORGET TO RE-COMPILE PETSc IF YOU ARE USING IT FOR YOUR CASES)

- Minor modifications to Jetstream source code to allow it to be compiled on new Sharcnet/Graham computer
- compile on Graham with:
./make_jetstream graham



- Added a general approach to measure thickness-to-chord ratio at any location on a 3D wing geometry specified by a spanwise and chordwise coordinate pair
- Added a general approach to measure the maximum thickness-to-chord ratio over a specified chordwise range at a given spanwise location
- The above fixed- and range-thickness measurements are used for evaluation of corresponding constraints
- The above fixed- and range-thickness measurements/constraints are only available when using the FFD approach for optimization
- The new thickness constraints use a least-squares minimization algorithm (Google "dtrnlspbc") contained in the MKL library that comes with current versions (greater than version 12) of the Intel ifort compiler

-Added morphing code to easily define DOFs on portions of Bspline geometry
-Added linear constraints:
-->linear&average wingtip constraints
->multiple variations of linear LE/TE constraints
->chord constraint restricted to region with DOF
->additions to the linear thickness constraint
->patch line constraint
-Added surface length constraint which can constrain surfLength on upper/lower surface independently or together
-Added the maxMach constraint to Bspline optiimizations
-Added changes to non-linear thickness constraint
-Added flap design variables with tip & twist constraints
-Added multidesign functionality

Changes To Input Parameters

Set following input parameters to use fixed- and/or range-thickness constraints:

jtstrm%thk_cnstrnt = .true.
jtstrm%rangethk_cnstrnt = .true.

Fixed and range-thickness constraints are defined in input files "tcon.dat" and "tconr.dat" respectively. See Jetstream Test Suite Case 043 for examples of input parameters and files.
