Plastic part design consideration plays a significant role in designing and manufacturing a plastic component. Whenever a Product Designer designs a plastic part, it is important to take care of factors such as the moulding process, selection of material, mass manufacturing process and overall area of the part around the functional need by keeping the design intent…

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…

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…

There are many ways to manage the performance of CATIA V5 & accuracy of models. To improve performance & increase productivity, we need to configure the settings properly. Some of these options are discussed in detail in this document. These will immensely benefit CATIA users. Undo Stack Undo ➞ Stack size ➞ change from 10 to 5…

With the help of Publications in CATIA V5, one can make different geometrical features available for use in the specification tree. One can publish a plane, a sketch or a parameter which is not readily visible in the specification tree. In assembly workbench, during Contextual Design, Publication option becomes very useful. In CATIA V5, go to Tools…
