Analysis

Analysis#

solve

Perform a static analysis.

trace

Perform a nonlinear static analysis with load factor control.

integrate

Perform a dynamic analysis.

eigen

Perform an eigenvalue analysis.

spectrum

Perform a response spectrum analysis.

Several additional aspects of the analysis procedure can be controlled in detail. These include:

  1. constraints – Manages the enforcement of constraint equations during the analysis

  2. numberer – Establishes the correspondence between equation numbers in the system of equations and the degrees of freedom at the nodes.

  3. system – Defines the storage and solution algorithm for the linearized residual equations \(\boldsymbol{A}x=\boldsymbol{b}\).

  4. test – Identifies when the analysis has achieved convergence.
