Analysis Connection Manager


Analysis Manager

All the objects making up an analysis document.
  Links Manager All the links managed from the CATAnalysis document to other documents: a part, result data or computation data.
  Finite Element Model: Models with representations used for performing computer-aided engineering analysis (CAEA) of products. They are complementary to computer-aided design (CAD) models, which are mainly geometric representations of products. 
  Adaptivity Process Any specification required for managing the process that will let you perform adaptativity computation (re-meshing).


Links Manager

All the links managed between the CATAnalysis document and other documents: a part, result data or computation data.
  Results Path to an external storage file directory (result data). 
  Computations Path to an external storage file directory (computation data).
  Link Any link to a part or a product (assembly).


 Finite Element Model
Models with representations used for performing computer-aided engineering analysis (CAEA) of products. They are complementary to computer-aided design (CAD) models, which are mainly geometric representations of products. 
  Static Case A procedure for the computation of the system response to applied static loads under given restraints.  
  Frequency Case A procedure for the computation of the system vibration frequencies and normal modes for a given non-structural mass distribution under given restraints.
  Buckling Case A procedure for the computation of the system buckling critical loads and buckling modes for a given Static Analysis Case.


 Nodes and Elements

Nodes and elements that can be created are either Smart Surface Mesh (FMS) or OCTREE (GPS) type.
  OCTREE Tetrahedron Mesh Automatic mesh specifications generating tetrahedron mesh elements and using OCTREE methods.


 Properties

Any specification applied to physical properties (geometry): material and thickness (surface), connections, virtual connections and virtual parts.
 
  Material Property3D A link to the material (either 2D or 3D) assigned to the part: name, support and thickness.


 Property Connections

Property Connections: assembly connections used to specify the boundary interaction between bodies in an assembled system.
  Fastened Connections Link between two bodies which are fastened together at their common boundary, and will behave as if they were a single body.
  Slider Connections Link between two bodies which are constrained to move together in the local normal direction at their common boundary, and will behave as if they were allowed to slide relative to each other in the local tangential plane.
  Contact Connections Link between two part bodies which are prevented from inter-penetrating at their common boundary, and will behave as if they were allowed to move arbitrarily relative to each other as long as they do not come into contact within a user-specified normal clearance.
  Pressure Fitting Connections Link between two bodies which are assembled in a Pressure Fitting configuration, more precisely when there are interferences or overlaps between both parts.
  Bolt Tightening Connections Connection that prevents bodies from penetrating each other at a common interface.
  Virtual Rigid Bolt Tightening Connections Connections used to specify the boundary interaction between bodies in an assembled system. This connection takes into account pre-tension in a bolt-tightened assembly in which the bolt is not included.
  Virtual Spring Bolt Tightening Connections Connections are used to specify the boundary interaction between bodies in an assembled system. This connection takes into account pre-tension in a bolt-tightened assembly in which the bolt is not included.
  Rigid Connections Connection that fastens bodies together at a common rigid interface.
  Smooth Connections Connection that fastens bodies together at a common soft interface.
  Spot Welding Connections Connection that fastens bodies together at a common soft interface.


 Virtual Parts
Structures created without a geometric support. They represent bodies for which no geometry model is available, but which play a role in the structural analysis of single part or assembly systems. Virtual Parts are used to transmit action at a distance.
  Rigid Virtual Parts Generates a stiff transmission rigid virtual part.
  Smooth Virtual Parts Generates a soft transmission rigid virtual part.
  Contact Virtual Parts Generates a contact transmission rigid virtual part.
  Rigid Spring Virtual Parts Generates a stiff transmission elastic spring virtual part.
  Spring Smooth Virtual Parts Generates a soft transmission elastic spring virtual part.


 Restraints
  Generates restraining joins, either on a geometry selection or on a virtual part or still various types of degree of freedom restraints.
Restraint Any combination of degrees of freedom on a geometry selection.
Isostatic

Statically determinate supports generated on a part.
Clamp Fixes all degrees of freedom on a geometry selection.
Surface Slider Generates surface constraint joins, which allow points of a surface to slide along a coinciding rigid surface (fixes the translation degree of freedom for a surface in the direction of the local normal).
Slider Generates prismatic joins (sliders), which allow a rigid body to translate along a given axis (fixes all degrees of freedom of a point, except for one translation).
Sliding Pivot Generates cylindrical joins (actuators) which allow a rigid body to translate about  and rotate around a given axis (fixes all degrees of freedom of a point, except for one translation and one rotation).
Ball Join Generates spherical joins (balls), which allow a rigid body to rotate about a given point (fixes all translation degrees of freedom of a point).
Pivot Generates conical joins (hinges), which allow a rigid body to rotate around a given axis (fixes all degrees of freedom of a point, except for one rotation).


  Loads
  Generates distributed force systems equivalent to given static resultants, force densities of given intensity or acceleration fields.
Pressure Generates pressure loads over a surface.
Distributed Force Generates a distributed force system equivalent to a pure force at a point (given force resultant and zero moment resultant).
Moment Generates a distributed force system equivalent to a pure couple (given moment resultant and zero force resultant).
Bearing Load Simulate contact loads applied to cylindrical parts.
Acceleration Generates a uniform acceleration field over a part.    
Rotation Force Generates a linearly varying acceleration field over a part.
Line Force Density Generates a line force field of given uniform intensity on a part edge.  
Surface Force Density Generates a surface traction field of given uniform intensity on a part face.  
Body Force Generates a volume body force field of given uniform intensity on a part.
Enforced Displacements Assigns non-zero displacement values to restrained geometric selections.


  Mass
  Non-structural mass densities of given intensity.
Distributed Mass Equipment Non-structural lumped mass distribution equivalent to a total mass concentrated at a given point.
Line Mass Densities Scalar line mass field of given uniform intensity on a curve geometry. 
Surface Mass Densities Scalar surface mass field of given uniform intensity on a surface geometry.


 Adaptivity Process
Adaptivity Convergence Creating global adaptive mesh refinement specifications and computing adaptive solutions.
Adaptivities Selectively refining the mesh in such a way as to obtain a desired results accuracy in a specified region.
Adaptivity Boxes Local specifications relative to the maximum error in the approximate computed solution relative to the exact solution.


 Sensors
Sensors A synthesis of analysis results which provide measures that can be re-used in Knowledgeware in order to set rules, checks and formulas.
Sensor sets Different types of object sets can be generated: 
Static case: misesmax (Maximum von Mises), dispmax (Maximum Displacement), reaction (Reaction on geometry associated to restrain and connection specifications) and globalerror
Frequency case: Frequency (Represents the frequency value) and Frequencies (Represents the list of the frequency values)
Buckling case: Buckling Factor
