Release of COSMOS/M Version 2.85 for Windows 98/2000/NT/XP

Dynamic Memory Allocation

• Eliminates size limitations of problems being analyzed.

• Store large program files by dividing them into individual blocks which may be stored in different locations. Ideal for networking environments.

• Combined Asymmetric loads with Axisymmetric Thermal and Gravitation.

• 2D Anisotropic material options for shell elements.

• Support of the J-Integral Element as a fracture criterion for Linear Static Problems.

• Supports Consistent Mass Representing for more accurate mass effects in dynamic response problems.

• Mode Selection Option allows users to select only those modes which are necessary for system response.

• Partial Correlation for Random Vibration Analysis.

• Uniform Rotational Base Motion (Small Rotations).

• Improvements of Radiation View Factor Calculation improve convergence and allow one surface to receive radiation therefore shielding another surface.

• Triangular Contact Sub-Surface Capability allows contact problems to use automatically meshed elements!!

• Automated Structure Stability for Gaps and Contacts.

• Stress vs. Time Graphs.

• Release Prescribed Displacements Several Times at any Degree of Freedom.

• "Modified" Finite Difference Method for Shock Loading, Impact and Wave Propagation.

• Enhanced BFGS Iterative Technique.

• Inclusion of Creep Effects in the J-Integral Evaluation.

• Addition of Nonlinear Buckling includes Bifarcation buckling which may be performed by DSTAR at any point during nonlinear analysis.

• Optimization/Sensitivity with ASTAR (Advanced Dynamics) and FSTAR (Fatigue).

• Automatic Determination of Curve Fitting Type.

• Optimum Design of Composites makes optimization of composites more accurate.

COSMOS/M Version 2.85 contains the COSMOS/FFE Dynamic production version.

• Concentrated Mass and Spring Elements Support allow for a wider range of dynamic analyses.

• Rigid Connection Between Shell and Solid Elements Support eliminates added equations.

• End Release Code for Beam Element Support.

• Rigid Connection Between Shell and Solid Elements Support eliminates added equations.

• Concentrated Mass and Spring Elements Support enhances the ease and analysis capabilities of older programs for general analysis applications.

• Nodal Concentrated Moments for Tetra and Solid Elements.

• Transient flow and\or heat transfer allows analysis of fluids and heat as a function of time.

• Two-Phase flows (humid or moist gas and steam/water mixture).

• Cylindrical coordinates allow problems to be solved in rotating coordinate frames.

• Spatially-Periodic Boundaries.

• Slip Walls provide symmetry boundary conditions that are not orthogonal, making it easier for users to analyze fluids.

• Unknown Boundary Conditions.

• Pyramid or 4-sided 3D Elements allow FLOWPLUS to work with elements generated by COSMOS/M.
