SBGAT V2.02.1

New

• Second-moments about the mean in the volume, center-of-mass, unit-densiy inertia tensor, principal moments, principal dimensions and orientation of the principal axes can now be evaluated through the static methods of SBGATShapeUncertainty
• SBGATShapeUncertainty provides two methods to evaluate the statistical moments: a monte-carlo method ComputeInertiaStatisticsMC, and another method ComputeInertiaStatistics leveraging a linearized uncertainty model as proposed by Bercovici and McMahon (Inertia statistics of an uncertain small body shape, ICARUS 2019 (In Review). Both methods take the same argument (correleation length l and the standard deviation governing the error in the control point coordinates, directed along the average normal at these points). Both these methods assume that the shape error can be described as normally distributed and zero-mean.
• Added a new function in Tests to illustrate the convergence of the Monte-Carlo shape uncertainty sampling to the analytical prediction

Improvements

• SBGATMassProperties::SaveMassProperties is now saving the average radius (r_avg = cbrt(3/4 *Volume/pi)) to the JSON file
• SBGATMassproperties::GetPrincipalAxes could return 4 dcms, all representative of the same inertia ellipsoid. To enforce stability in the principal axes extractions, SBGATMassproperties::GetPrincipalAxes now returns the dcm that has the smallest-norm corresponding MRP.
• SBGAT will try to link against OpenMP by default. This behaviour can now be disabled by passing the --without-libomp flag to Homebrew or by passing the -DNO_OMP:BOOL=TRUE flag to CMake

Bug fixes:

• Fixed potential bug in SBGATPolyhedronGravityModel involving a parallel computing block where a variable with no viable reduction clause was being operated on
• SBGATMassproperties::GetPrincipalAxes is now returning the DCM [PB] converting from the body coordinate frame to the body principal frame. It was previously returning [BP]
