Summary of Changes
- Added sectional area constraints to be used for aerodynamic shape optimization problems. Coded as inequality constraints such that wing sectional areas at prescribed spanwise locations must be greater than or equal to target sectional areas. Spanwise locations and corresponding target sectional areas are defined in an input file named //secAreaCons.dat//. When using sectional area constraints, an output file with suffix //.sacon// contains a history of sectional areas at each design iteration. See Jetstream Test Suite case 033 for an example optimization that uses sectional area constraints. - Fixed bugs pertaining to opt_method = 'split_opt', it should work properly now.

Changes To Input Parameters
To use sectional area constraints, set JTSTRM% secAreaCon = .true. in the Jetstream input parameters file.

Changes to Subroutines
Commented code in calcXiParams has now been moved to refineXiParams. readGridSplit now calls refineXiParams instead of calcXiParams.
