Data Consistency And Conflict Avoidance In A Multi-User Cax Environment, Robert Aaron Moncur Jul 2012

Data Consistency And Conflict Avoidance In A Multi-User Cax Environment, Robert Aaron Moncur

Theses and Dissertations

This research presents a new method to preserve data consistency in a multi-user CAx environment. The new method includes three types of constraints which work by constraining and controlling both features and users across an entire multi-user CAx platform. The first type of constraint includes locking or reserving features to enable only one user at a time to edit a given feature. The second type of constraint, collaborative feature constraints, allows flexible constraining of each individual feature in a model, and the data that defines it. The third type of constraint, collaborative user constraints, allows the constraining of user permissions …


Multi-User Methods For Fea Pre-Processing, Prasad Weerakoon Jun 2012

Multi-User Methods For Fea Pre-Processing, Prasad Weerakoon

Theses and Dissertations

Collaboration in engineering product development leads to shorter product development times and better products. In product development, considerable time is spent preparing the CAD model or assembly for Finite Element Analysis (FEA). In general Computer-Aided Applications (CAx) such as FEA deter collaboration because they allow only a single user to check out and make changes to the model at a given time. Though most of these software applications come with some collaborative tools, they are limited to simple tasks such as screen sharing and instant messaging. This thesis discusses methods to convert a current commercial FEA pre-processing program into a …
