# GiD + OpenSees Interface *(c) 2016-2023* *Lab of R/C and Masonry Structures, School of Civil Engineering, Aristotle University of Thessaloniki, Greece* **Development team** - T. Kartalis-Kaounis, Dipl. Eng. AUTh, MSc - K. Mixios, Dipl. Eng. AUTh, MSc, PhD cand. - V.K. Papanikolaou, Dipl. Eng., MSc DIC, PhD, Assoc. Prof. AUTh **Project contributors** - F. Derveni, Dipl. Eng. AUTh, PhD - G. Ntinolazos, Dipl. Eng. AUTh - T. Papadopoulos, Dipl. Eng. AUTh, MSc - V. Protopapadakis, Dipl. Eng. AUTh, MSc - T. Zachariadis, Dipl. Eng. AUTh, MSc --- ### KNOWN ISSUES --- - In order to view the generated .tcl file ('Create and view .tcl only' menu option), first associate the .tcl extension with your favorite text editor (e.g. Notepad, Notepad++ etc.). - OpenSees does not combine constraints (multiple 'fix' commands on the same node). As a result: - Intersection joints that belong to two lines with different constraints should be handled separately. - Intersection lines that belong to two surfaces with different constraints should be handled separately. - The horizontal information bar stays in front of GiD material/condition windows when the respective menu options are used; please use the toolbar buttons instead. However, there's no way at the moment to hide the information bar behind the GiD Layer and Copy windows. --- ### VERSION HISTORY --- **Version 3.0.0-beta (30/11/2023)** - Added : **Python output** for OpenSees models - Added : Set material properties as variables in Python-based models - Various fixes and improvements --- **Version 2.9.6 (30/07/2022)** - Added : Base shear (z = 0 for 3D or y = 0 for 2D) in analysis results - Added : Modal results in eigenvalue analysis - Various fixes and improvements --- **Version 2.9.5 (19/05/2022)** - Improved : fiber mesh suggestions for fiber sections (thanks to C.
