This is a description of CalculiX CrunchiX. If you have any problems using the program, this document should solve them. If not, send us an E-mail dhondt t-online. The next sections contain some useful information on how to use CalculiX in parallel, hints about units and golden rules you should always keep in mind before starting an analysis. Section five contains a simple example problems to wet your appetite. Section six is a theoretical section giving some background on the analysis types, elements, materials etc.

Input deck format This section describes the input of CalculiX. The jobname is defined by the argument after the -i flag on the command line. When starting CalculiX, it will look for an input file with the name jobname. CalculiX will generate an output file with the name jobname. The latter can be viewed with cgx. If any of the files it needs does not exist, an error message is generated and CalculiX will stop. The input deck basically consists of a set of keywords, followed by data required by the keyword on lines underneath the keyword.
The keywords can be accompanied by parameters on the same line, separated by a comma. If the parameters require a value, an equality sign must connect parameter and value. Blanks in the input have no significance and can be inserted as you like.
The keywords and any other alphanumeric information can be written in upper case, lower case, or any mixture. The input deck is case insensitive: internally, all alphanumeric characters are changed into upper case.
The data do not follow a fixed format and are to be separated by a comma. A line can only contain as many data as dictated by the keyword definition. The maximum length for user-defined names, e. The structure of an input deck consists of geometric, topological and material data before the first step definition, and loading data mechanical, thermal, or prescribed displacements in one or more subsequent steps. The user must make sure that all data are given in consistent units the units do not appear in the calculation.
A keyword can be of type step or model definition. Step keywords can only be used within a step. Node and element sets can share the same name. Keyword cards in alphabetical order:.

The method used is the finite element method. The solver is able to do linear and non-linear calculations. Static, dynamic and thermal solutions are available. Both programs can be used independently.
