10.1 Overview

Files of type input may start with a

*HEADING

followed by a comment, e.g. a short problem description.



Furthermore, such files are organized through sections. Every section starts with a section keyword which may be followed by options in the same line. Options and keywords are generally separated by commas.

The following section keywords are currently used:

 

followed by

*NODE

Nodal data

*SOLID SECTION   

Definitions for bars, trusses, plates with reference

 

to material types and element types

*BEAM SECTION

Definitions for beam structures with reference

 

to material types and element types

*SHELL SECTION

Definitions for slab and shell structures with reference

 

to material types and element types

*MATERIAL

Material types and their parameters

*ELEMENT

Element data

*BEAM REINF

Reinforcement data

*STEP

Definitions for type of simulation, the incrementally

 

iterative procedure to be used, boundary conditions,

 

loading and output intervals



Each section keyword marks a section header.

A section keyword *STEP marks a simulation step. Steps have to be distinguished from time increments.

A whole simulation must have at least one step but may consist of a sequence of steps, e.g. a step with a dynamic simulation may follow a quasistatic simulation whereby the final state of the former defines the initial state of the latter.

A line with leading ** may be used as comment line and is ignored. Leading blanks, intermediate blanks and blank lines are generally ignored.
