Product Upgrades

SENSE Version 1.1.1 (released 2/01/02)

• Added direct solver which performs an LU decomposition of the entire LHS matrix. This provides the sensitivities in one step for 2-D problems.
• The primitive flow variables are now imported through the solnmgr. For Spalart-Allmaras computations, add the Spalart eddy viscosity. For two-equation calculations, add K and omega.
• Using an alternate solution for high-order near-by extrapolation has been disabled.
• Memory estimates from the solnmgr have been updated to reflect added capabilities.
• Output support for unformatted binary and iblanking.
• License management software has been upgraded.

SENSE Version 1.1.0 (released 7/20/00)

• Support for zero, one and two-equation turbulence modeling (Baldwin-Lomax, Spalart-Allmaras, Wilcox, k-w).
• Output variables added for turbulence data (for example, y+, k+, P/e, Reynolds stresses, corresponding sensitivity data).

SENSE Version 1.0.4 (released 9/1/99)

• Tangency boundary condition improved for geometric design variables.
• More parallelism (99.2% of the code is now parallel).
• An error magnification factor is output for integrated data.
• Output of more flow-gradient data (density and velocity components).
• Cosmetic changes to the input file to support future releases.

SENSE Version 1.0.3

• Implicit zonal boundaries with zone parallel capability. This feature dramatically improves CPU performance for zonal-boundary problems.
• Domain decomposition utility has been added to utilize the implicit zonal-boundary capability on multi-tasking machines.
• Added block-Jacobi inner iterations. This scheme is the fastest per inner iteration, but the least robust for general problems and the convergence rate is the slowest of the schemes.
• Added block Jacobi and line Jacobi as preconditioners for GMRES. The most robust scheme still remains to be GMRES/ILU(0).
• Near-by Taylor series approximations can be output in conservative variables. The advantage here is that the conservative field can be imported back into SENSE to march through the design space without running a flow solver again.
• Alternate flow fields can be used in the post-processing utility FIELD and PLOT. This feature allows for second-order mid-point ODE methods to march through the design space.
