After the basic model has been constructed, click Analysis > Dynamics or Dynamic Analysis to perform a dynamic analysis. The Dynamic Analysis window opens.

Toolbar Commands

Analysis
Type

Specifies the type of analysis. Select Modal, Harmonic, Earthquake (spectrum), Relief Loads (spectrum), Water Hammer/Slug Flow (spectrum), or Time History. The window tabs change for each analysis.

Save Input and File > Save Input - Saves entered values to the CAESAR II file.

Check Input and File > Check Input - Opens the Dynamic Syntax Check dialog box to check entered values for errors.

Run the Analysis and File > Run Analysis - Performs the error check and, if no errors are found, performs the analysis the dynamic analysis for the selected Analysis Type and the entered values. Analysis results are then available for review. For more information, see Analysis Results.

Add Entry and Edit > Add Entry - Adds a row to the table.

Delete Entry and Edit > Delete Entry - Deletes a row from the table.

Enter/Edit Spectrum Data and Tools > Spectrum Data Points - Specifies spectrum data for manually-entered or ASCII-file-based spectrum definitions. For more information, see Enter/Edit Spectrum Data.

DLF/Spectrum Generator and Tools > DLF Spectrum Generator - Converts spectrum time waveform excitation data into a frequency domain dynamic load factor (DLF) curve or other response spectrum. For more information, see DLF/Spectrum Generator.

Relief Load Synthesis and Tools > Relief Load Synthesis - Calculates the magnitudes of relieving thrust forces. For more information, see Relief Load Synthesis.

Cmt

Changes the selected row in the table to a comment line. You can add comment lines anywhere in the table.

Modal Analysis

Harmonic Analysis

Earthquake Response Spectrum Analysis

Relief Loads and Water Hammer/Slug Flow Spectra Analysis

Time History Analysis

Dynamic analysis uses the units from the piping input file or from the configuration file of a structural-only analysis. For more information on dynamic load cases, data, and procedures, see External Interfaces.

If the model contains spring hangers selected by the software or nonlinear boundary conditions (such as single directional supports, gaps, rods, or friction), then a static analysis must be performed before the dynamic analysis to determine how the nonlinear supports are acting.
