Description:
Selects the mode of operation for Jetstream
Parameter Type:
String
Range of Acceptable values:
flowsolve, optimize, jacobian, test_prec, chk_metrics, verifyorder, fluxbalance, test_viscjac, adjsolve, extract_geom, mesh_move, design_sweep, mesh_resize, dirderiv,........and the list goes on,........ (See jetstream.f90 for the full list)
Default Value:
none
JTSTRM% SNOPT_VIOLATION_LIMIT
Description:
Defines an absolute limit on the magnitude of the maximum constraint violation after the linesearch. See SNOPT User's Manual for details.
Parameter Type:
Double precision
Range of Acceptable values:
0.0 to +1e20
Default Value:
+1e6
JTSTRM% USE_IPOPT
Description:
Allows the use of IPOPT optimization algorithm instead of SNOPT. See documentation for IPOPT at https://projects.coin-or.org/Ipopt
Parameter Type:
Logical
Range of Acceptable values:
.true. or .false.
Default Value:
.false.
JTSTRM% secAreaCon
Description:
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.
