    The latest 4.3 release contains significant improvements in its popular Progressive Failure Analysis (PFA) module and translation support for NASTRAN, ABAQUS and ANSYS. Included in this release are 50 Step-by-Step Tutorial examples that fulfill a diverse range of applications and engineering needs.
    4.3 also features the new A- & B- Basis Allowable module which may be viewed through GENOA's Web Demo.  Users who are interested in applying their own data in this module may try GENOA through the on-line CVT web service for 3 free months.  For more information, please contactsales@ascgenoa.com.
    GENOA is an engineering software suite that augments commercial Finite Element Analysis (FEA) packages by providing Progressive Failure Analysis (PFA) capability. It can investigate structural responses to material degradation from damage induced by static, cyclic (low and high cycle fatigue), impact, Power Spectrum Density (PSD) and thermal loading.
