Analysis

Description

Static stress analysis

Use these procedure when inertia effects can be neglected.  The analysis may be linear or nonlinear.

Heat transfer analysis

Use these procedure to solve problems with conduction, forces convection, boundary radiation, convection, and cavity radiation.  Procedures are available for sequentially and fully coupled themal stress analysis.

Transient dynamic analysis

Obtains response histories for linear or nonlinear events using direct integration of equations of motion.

Natural frequency extraction

Extract natural frequencies of the structure, including any prestress effects.

Linear dynamic analysis

Uses modal superposition to perform response spectrum, time history, steady-state harmonic response, or random response analyses

Adiabatic analysis

Used in dynamic cases where mechanical deformation causes heating, and the event is so rapid that heat diffusion is not possible in the material.

Geostatic stress states

Procedures are available for properly defining the initial conditions of deostatic steady-state equilibrium problems.

Coupled pore fluid diffusion and stress analysis

The *SOILS procedure provides capabilities for modeling coupled pore fluid diffusion/stress analysis problems involving partially and/or fully saturated fluid flow.

"Visco" analysis

Use this procedure to govern a step of transient response with time dependent material behavior (creep, swelling and viscoelasticity). Includes rate effects but no inertial effects.

Eigenvalue buckling prediction

These procedures are used to obtain eigenvalue buckling estimates.

Coupled thermal-electrical analysis

Use this procedure to model Joule heating with temperature dependent electrical conduction.
