The GiD+OpenSees Interface

How it Works

The GiD+OpenSees Interface can be easily installed upon existing GiD and OpenSees installations (32 or 64 bit), adding a new 'OpenSees' problemtype in the GiD Data menu. After creating a new model and selecting the 'OpenSees' problemtype, the user can easily model any geometry (1D, 2D, 3D elements or combinations of these) and, at the same time, assign materials, sections, restraints, loads etc. to the existing model using the available toolbar buttons. Moreover, the analysis type and various other parameters can be configured. When the model is ready, OpenSees is executed just by pressing the Analysis button. More information on modeling using the GiD+OpenSees Interface can be found in the project Wiki and Videos sections.

Depending on the model size, the analysis can take from a few seconds to several hours. During this time, the OpenSees command line window remains visible, and the respective analysis log is displayed. After the end of the analysis, all OpenSees results are automatically transferred to the GiD graphical postprocessor, for user evaluation.

The interface supports both linear and nonlinear static and dynamic analysis for a wide range of elastic and inelastic elements, as well as the capability of multiple model domains (i.e. sets of elements with different DOFs), for easy modeling of soil-structure interaction (SSI) problems.
