This article describes the use of the tool GiD as a pre- and post-processor for a 2D analysis of a soil continua in OpenSees. Two separate procedures are made available for download, one which creates an input file for an effective stress analysis using nine node quadrilateral elements, and one which creates an input file for a total stress analysis using four node quadrilateral elements. Only the former procedure will be described in this article, as the procedure for the four node elements is very similar, but less complex. The nine node element procedure discussed in this article was used to develop the input file for the Dynamic Effective Stress Analysis of a Slope example posted in the practical examples section of this manual.
GiD can be used for many purposes, one of which is as a pre- or post-processor for a finite element package. For pre-processing, the interaction between GiD and a particular outside program is fully customizable via a series of files called a problem type. The files which make up the problem type define things such as which materials can be used, which conditions such as nodal degrees of freedom or fixities can be assigned, and the formatting and syntax of the input file which is generated from the GiD mesh. Further information on pre-processing using GiD, or the use of GiD in general, can be found in the GiD manual.
The files which define the nine node element procedure discussed in this article include:
- The GiD problem type, UWnineQuad2Dup.gid, which consists of the following individual files:
- UWnineQuad2Dup.bas, the main file which defines how the OpenSees input file is generated from the GiD input
- UWnineQuad2Dup.mat, a file which defines materials for use in GiD
- UWnineQuad2Dup.cnd, a file which defines certain conditions necessary for the analysis for use in GiD
- UWnineQuad2Dup.bat, a batch file which renames the file output by the procedure as directory_name.tcl
- UWnineQuad2Dup.tcl, a file containing two tcl procedures necessary to the creation of the input file
The files which define the four node element procedure include:
- The GiD problem type, UWquad2D.gid, which consists of the following individual files which have corresponding descriptions to those listed above:
- UWquad2D.bas
- UWquad2D.mat
- UWquad2D.cnd
- UWquad2D.bat
