NISA V15 New Features
- The multiple support excitation capability is now available in the shock spectrum feature of NISA II to handle non-uniform support excitation problems. USNRC modal combination rules with and without missing mass correction is utilized.
- Seventeen new crack propagation configurations are now included with ENDURE Shell. Also, FEM models for plates, pipes and elbows with blunt cracks can now be generated automatically for user specified geometric dimensions and applied loads.
- 3D-Magnetodynamic analysis without massive conductors for harmonic current sources is now supported in NISA/EMAG using the magnetic vector potential approach. Also, 3D-Transient Magnetic analysis with and without massive conductors for arbitrary time varying current sources is available using the magnetic vector potential and electric scalar potential approach
- SAT 2 NEUTRAL translator is now upgraded to support ACIS R15 Geometry Kernel. SolidWorks™ 2007 and IGES Version 5.3 are also now supported. CAD translators such as ProE™ to Neutral, Advanced IGES to Neutral, CATIA V4™ to Neutral and CATIA V5™ to Neutral are now available.
- NISA is now faster with upgraded Sparse and Iterative Solvers.
- DISPLAY now enables viewing of realistic plot for 3-D Beam, 3-D General Beam, 3-D Straight pipe & 3-D Elbow elements. DISPLAY also allows viewing of input function such as time function and spectra as a graph.
- NISA/3D-FLUID-Incompressible Flow module now computes Reynolds' and Peclet numbers and also prints them in the output file.
- NISA/HEAT now calculates heat flux due to convection and radiation boundary conditions.
- An improved FEA data two-way translation for NISA & ANSYS™, NISA & NASTRAN™ and NISA & STAAD3™ is now available.
- The new Application Launcher is highly intuitive and enables users to have a single point access to all NISA modules.
- ENDURE now supports fatigue crack initiation theory based on the MANSON approach.
- ENDURE pre-processing now has an option to graphically select nodes lying on the crack mouth or crack front. Variation of stress triaxiality along a line of nodes with respect to distance from the crack front, crack mouth opening displacement graph, calculation of crack opening area are now available in DISPLAY.
- Post processing of stress resultants at element Centroid for shell elements and post processing of stresses for non-linear beam element (NKTP 39) are now available in DISPLAY.
- NISA II now has a general spring plus damper element. Three translational damping coefficients and rotational damping coefficients can also be specified in addition to stiffness coefficients.
- DISPLAY IV now allows users to navigate analysis data input for static, non-linear static, Eigen value and buckling analysis.
- Fluid quantity integration along a given edge or face is now implemented in DISPLAY for Fluid Analysis.
