Introduction The RCC structure displayed below is subjected to displacement under static conditions in ABAQUS GUI. The basic purpose of using RCC is to absorb stresses (specifically tensile stresses) that arise in the structure. From a structural engineering point of view, concrete is weak in tension, and therefore it is reinforced accordingly with suitable material. To overcome…
Negative eigenvalue messages are generated during the solution process when the system matrix is being decomposed. The messages can be issued for a variety of reasons, some associated with the physics of the model and others associated with numerical issues. An example of the message that is issued is: ***WARNING: THE SYSTEM MATRIX HAS 16 NEGATIVE EIGENVALUES.…
This blog explains the different errors encountered while using Abaqus/Explicit and the ways to debug and troubleshoot them. Tracking Difficulties Reason: By default, Abaqus/Explicit uses a fast, local tracking algorithm to track the penetration of a slave node into the master surface; at a frequency of every 100 increments (the user can change this default), Abaqus/Explicit performs a…
Customization of toolbars helps a regular CATIA V5 user for executing day to day tasks and also to increase productivity. One can customize the toolbar to include the frequently used commands, so that the user has a smooth and seamless experience while using CATIA. The user need not search for each and every command in the respective…
Environment variables in CATIA are used to customize the CATIA environment as per the user requirements. There are some Environment Variables which help to start CATIA faster. Though they are not documented, they are used by the user community as they work well with the current supported CATIA release. To add these variables to your current Windows…
While running the analysis on a model with contacts, a major problem arises i.e. convergence. It is not just because of single reason, that it can be resolved in an easy way. When you come across such problems in different types of analysis, job will terminate by showing an error message or a set of warnings in…
