• The ProSolve module functions vfx_ProSolveGetParami, vfx_ProSolveGetParamd and vfx_ProSolveGetParamc have been added to query all associated set parameters. (4.4.3 July 31, 2017)

• The ProSolve module parameters for out of core factor control have been changed. Enable out of core factor storage using vfx_ProSolveSetParami with parameter PROSOLVE_FACTOR_OOC. Set the out of core factor file name using vfx_ProSolveSetParamc with parameter PROSOLVE_FACTOR_FILE. (4.4.3 July 20, 2017)

• The ProSolve module now supports out of core eigenvector storage. Enable out of core eigenvector storage using vfx_ProSolveSetParami with parameter PROSOLVE_EIGEN_OOC. Set the out of core eigenvector file name using vfx_ProSolveSetParamc with parameter PROSOLVE_EIGEN_FILE. (4.4.3 July 20, 2017)

• The ProSolve module parameter PROSOLVE_SOLVER values have been changed. The new options select direct or iterative methods for symmetric and non-symmetric matrices. The out of core option is not set separately with a dedicated parameter PROSOLVE_FACTOR_OOC. (4.4.3 July 20, 2017)

• The ProSolve module now has full support for NASTRAN CBUSH/PBUSH, CONM1 and CONM2 elements and properties. (4.4.3: May 30, 2017)

• The ProSolve module now has support for node and element set selection for results output. (4.4.3: May 30, 2017)

• The ProSolve module now supports parallel computation of mass, stiffness, geometric stiffness and results output. (4.4.3: May 30, 2017)

• The GenMCase module constraints for inertia relief have been simplified. (4.4.2: October 13, 2016)
  The ProSolve module parameters PROSOLVE_ORIGCODE and PROSOLVE_ORIGVERSION have been added to allow customization of the GProp object when writing the model information to a file. (4.4.2: October 6, 2016)

• The ProSolve module parameter PROSOLVE_MPCTYPE default has been changed to VFX_MPCTYPE_TRANSFORM. (4.4.2: October 6, 2016)

• The ProSolve module now supports the generation of thermal superelements. The output consists of reduced conductivity and capacitance matrices. (4.4.0: December 14, 2015)

• The ProSolve module now supports a singular mode solution type. This is a unique and efficient method for computing the number of singular modes and the modes themselves. (4.3.6: August 11, 2015)

• The ProSolve module now supports "sensor" node control of load case factors. This feature is only supported for transient analysis. (4.3.6: August 11, 2015)

• The ProSolve module function vfx_ProSolveSetNumThreads has been added to support coarse grained shared memory parallelization element matrix and vector formation, system degree of freedom reordering, matrix reduction and eigensolution. The underlying direct sparse solver is currently only fine grained parallelized within the BLAS routines. (4.3.1: March 17, 2014)

• The ProSolve module has been enhanced to support reduced vector computation during superelement analysis and kinetic energy output output requests. A specific output solution procedure has also been added. (4.3.1: March 20, 2014)
