A static analysis considers time invariant loading and structure response, and is specified for most analyses that do not contain wave loading.
The restart facility is described in detail in Restart Analyses, but a brief introduction to the topic is appropriate at this juncture to provide a background to static analysis.
Restart Analyses
A given design condition will typically require a structure to withstand a combination of static and dynamic loads and displacements. In performing a Flexcom analysis for these inputs, it should be possible to apply all static and dynamic loads and displacements in a single dynamic run. However, this is frequently not possible, and is rarely desirable. A better option is to invoke the program Restart facility, whereby you can specify that a particular analysis is to be restarted from a previous run, to build up to the full dynamic solution in stages. In a restart, the structure configuration at the end of the preceding analysis becomes the starting configuration for the restart. New loads or displacements are combined with those in the preceding run, and the structure response to the combined loading is found in a static or dynamic solution.
Further information on static analysis is contained in the following sections:
•Time Variables in Static Analysis describes the significance of time variables in a Flexcom static analysis and explains the rationale behind their inclusion.
•Solution Criteria Automation describes the solution criteria automation feature, which allows you to specify desired values of critical solution parameters. The program automatically adjusts the model configuration to satisfy the specified criteria.
•*ANALYSIS TYPE is used to specify the analysis type.
•*TIME is used to define time parameters for an analysis.
•*CRITERIA is used to specify certain criteria that need to be satisfied in a static analysis, and to define how the model is to be adjusted to satisfy the desired criteria.
