Some Motivation: Why We Are Engineers: Basic Actions of Problem Solving: Understanding the problem Simulation can be very useful to help understand what factors are important. Generate possible solutions to the problem The solutions that the designer can come up with are very dependent on the designer's experience and knowledge. Evaluate solutions Simulation can provide […]

  Engineering Design Problem: When we design, we would like to: Improve product or process quality Reduce life cycle costs Reduce development lead times This can happen during the initial design phase or sometime during the product's life. The design process starts by generating ideas – the functional performance of these ideas has to be verified. There […]

On this page, example assignments from 2014 of Stellenbosch University's Mechanical Engineering department will be set up using Patran and solved using MSC Nastran. For complicated geometry cleanup and preparation, MSC Apex may be used. The assignments were prepared by Dr Martin Venter from Stellenbosch University's Mechanical Engineering department. The videos on this page will […]

Whether you are testing a new concept or evaluating the functioning of a complex system like a car, a truck or a train or even the DVD tray of your home theater system, it can only be done successfully using MultiBody Dynamics simulations (MBD). Adams from MSC Software is the de facto standard when it […]

Question After I ran the model and attached the results, nothing was available. I found the following message in the .F06 file: "USER FATAL MESSAGE 9050 (SEKRRS) ^^^ RUN TERMINATED DUE TO EXCESSIVE PIVOT RATIOS IN MATRIX KLL. ^^^ USER ACTION: CONSTRAIN MECHANISMS WITH SPCi/SUPORTi ENTRIES OR SPECIFY PARAM,BAILOUT,-1 TO CONTINUE THE RUN WITH MECHANISMS.
