      Description

      A script using the Nplate capability defined 6 plates. The following command was also used.

      Fermi.NPlateSRPAddEqualityConstraint =

      {BP1, BP2, BP3, BP4, BP5, BP6}

      The command above means that we have essentially one area coefficient solve for. The area coefficients for the 6 plates should be the same.

      However, the GMAT output shows different values for the area coefficients:

      Fermi.BP1.AreaCoefficient.1 = 0.929705831367
      Fermi.BP2.AreaCoefficient.1 = 1
      Fermi.BP3.AreaCoefficient.1 = 1
      Fermi.BP4.AreaCoefficient.1 = -21.7611924239
      Fermi.BP5.AreaCoefficient.1 = 1
      Fermi.BP6.AreaCoefficient.1 = 290.65810322

      Additionally, it appears that GMAT is solving for more than one area coefficient which should not be the case:

          • Performed normal matrix reduction for Fermi.BP2.AreaCoefficient.1
          • Performed normal matrix reduction for Fermi.BP3.AreaCoefficient.1
          • Performed normal matrix reduction for Fermi.BP5.AreaCoefficient.1
          • Performed normal matrix reduction for Fermi.BP2.AreaCoefficient.1
          • Performed normal matrix reduction for Fermi.BP3.AreaCoefficient.1
          • Performed normal matrix reduction for Fermi.BP5.AreaCoefficient.1
