Various Analysis Cases

Linear Static Analysis
Linear static analysis is the basis and starting point of all analyses, examining the deformation and strength stability of a structure under external loads. In linear static analysis, the material must behave according to Hooke's Law within the elastic range, and deformation must be small enough that the resulting change in structural stiffness is negligible. Boundary conditions must not change while the load is applied and the structure deforms.
- Key Features
  - - Suitable for models containing complex NURBS patches and sliver faces
  - - Rigid body and spring element functions
  - - Linear contact support
  - ・ Welded behavior contact
  - ・ Bidirectional sliding contact
  - ・ General contact
  - - Various load / boundary condition support
  - - Thermal deformation / thermal stress analysis due to temperature differences
Modal Analysis
Modal analysis identifies the natural frequencies of a structure and the deformation shape (mode shape) at each natural frequency, predicting resonance and the deformation shapes caused by vibration.
- Key Features
  - - Check natural frequencies and mode shapes
  - - Modal participation factors and effective mass results
  - - Eigenvalue range specification, Sturm sequence check (missing eigenvalue check)
  - - Prestress can be considered
  - - Linear contact support
  - ・ Welded behavior contact
  - ・ Bidirectional sliding contact
Linear Dynamic Analysis
An analysis that captures the behavior of a structure under dynamic loads that vary with time, executed basically by direct integration of the equations of motion. Depending on the type of dynamic load, transient response, frequency response, random vibration, and response spectrum analysis methods can be applied.
- Key Features
  - - Direct and modal analysis methods
  - ・ Transient Response
  - ・ Frequency Response
  - ・ Random Vibration
  - ・ Response Spectrum
  - - Various damping effects (modal/structural, frequency-dependent)
  - - Design spectrum databases of major countries
Heat Transfer/Thermal Stress Analysis
A steady state is when an object and its surroundings are at the same temperature; in this state, the conditions generating heat flow, the heat flow rate, and the temperature distribution are constant with no change over time. Heat transfer analysis [steady state] analyzes the heat flow and temperature distribution in such a steady state. If the material properties and boundary conditions entered in heat transfer analysis [steady state] are temperature-dependent, nonlinear heat transfer analysis is required. If the input values do not change with temperature, linear heat transfer analysis is performed.
- Key Features
  - - Steady-state heat transfer analysis
  - - Transient heat transfer analysis
  - - Various load conditions such as heat generation, conduction, convection, radiation, and heat flux
  - - Thermal contact function for heat conduction between discontinuous parts
Nonlinear Static Analysis
Nonlinear static analysis solves material nonlinearity where material properties become nonlinear as loads gradually increase, geometric nonlinearity where the direction, distribution, and magnitude of loads change with large displacements or rotations, and "boundary nonlinearity" problems such as contact caused by nonlinearity at element boundaries or changes in boundary conditions.
- Key Features
  - - Material nonlinearity
  - ・ Elasto-plastic and hyperelastic models
  - ・ Isotropic and kinematic hardening behavior
  - - Geometric nonlinearity
  - ・ Large displacement and large rotation
  - ・ Follower forces
  - - Contact nonlinearity
  - ・ Welded, sliding, and general contact functions
  - ・ Various load increment and stiffness update methods
