We hope that our web site provides a great deal of valuable technical information, which is available to anyone who visits our web site. The technical materials on this page, however, are intended only for DRD's customers, and are, therefore, password protected. We provide these materials to our customers as a benefit for doing business with DRD, and at our discretion we provide them to selected DRD friends and associates.

The topics on this page are intended for engineers who are interested in highly technical and detailed information on ANSYS. These topics contain information, which is not readily available to ANSYS users through standard documentation and training courses. For example, some topics provide information on ANSYS capabilities that are under development or are not documented.

ANSYS Simplorer for Mechanical Systems (October 2017). DRD conducted this webinar on October 3, 2017. ANSYS Simplorer is a powerful platform for modeling, simulating and analyzing system-level digital prototypes. Simplorer enables you to verify and optimize the performance of your software-controlled, multidomain systems. With flexible modeling capabilities and tight integration with ANSYS 3-D physics simulation and embedded software design, Simplorer provides broad support for assembling and simulating system-level physical models to help you connect conceptual design, detailed analysis and system verification.

This webinar provides an introduction to ANSYS Simplorer for mechanical systems, and it provides a summary of several models that DRD solves in its ANSYS Simplorer for Mechanical Systems course. The webinar concludes with a detailed demonstration of a gas regulator model, which imports as a a Reduced Order Model (ROM) an ANSYS Mechanical nonlinear diaphragm finite element model.

All ANSYS Mechanical Enterprise customers current on maintenance have access to ANSYS Simplorer!

Engineering Fatigue Life Prediction and the ANSYS Mechanical Fatigue Module (October 2017). DRD conducted this webinar on October 2nd and 9th in 2017. The posted content is for the October 9th broadcast. This 75-minute webinar provides an introduction to engineering fatigue life prediction and the ANSYS Mechanical Fatigue module, which is available in ANSYS Mechanical Pro, ANSYS Mechanical Premium and ANSYS Mechanical Enterprise. We cover basic concepts including stress life and strain life methods, SN curves, alternating stress, mean stress and mean stress correction, elastic-plastic strain correction methods, and proportional and nonproportional loading. This webinar also provides detailed live demonstrations of the ANSYS Fatigue Module - one showing an example of stress life fatigue and the other showing an example of strain life fatigue.

ANSYS Mechanical Thermal Modeling (June 2017). DRD conducted this webinar on June 16, 2017. ANSYS Mechanical provides a powerful tool set for thermal modeling for problems dominated by conduction heat transfer through solid materials, and this webinar provides a comprehensive overview of these capabilities through three demonstration models.

The feature demonstration is a live walk through demonstration of a hazardous material enclosure subjected to a fire. This model includes:

  • Transient Thermal Analysis
  • Conduction through Metal
  • Free Convection on External Surfaces with Temperature Dependent Convection Coefficients
  • Radiation Heat Transfer including View Factor Calculations
  • Temperature Dependent Thermal Conductivity

The webinar includes two additional and shorter demonstrations that cover thermal fluid flow and thermal stress analysis.

Additive Manufacturing and Topology Optimization (April 2017). DRD conducted this webinar on April 26, 2017. This webinar starts by explaining the connection between Topology Optimization and Additive Manufacturing, and it then proceeds to provide an overview and demonstration of ANSYS Topology Optimization in ANSYS 17.

Fracture Mechanics Capabilities in ANSYS Mechanical Enterprise (February 2017). DRD conducted this fracture mechanics webinar February 09, 2017. This webinar provides a comprehensive overview of the fracture mechanics capabilities in ANSYS Mechanical Enterprise at ANSYS 17.

Engineers frequently need to answer the questions: 

  • Will the crack in my structure grow? 
  • Will the crack grow and then arrest, or will the crack lead to a complete part fracture? 
  • How long and how many load cycles will the structure last before a compete part fracture occurs? 

This webinar provides a very concise overview of linear elastic and elastic-plastic fracture mechanics. Then we proceed to show demonstrations of crack models in ANSYS including elliptical, pre-meshed, and arbitrary cracks. The webinar also covers postprocessing of ANSYS fracture mechanics models and the calculation of fracture entities such as stress intensity factor (SIF), J integral, and energy release rate. DRD also demonstrates ANSYS' ability to automatically grow cracks using the XFEM technique.

ANSYS Rotordynamics Webinar (January 2017). Rotordynamics is the study of rotating structures and their vibration characteristics. Applications include jet engines, steam turbines, disk storage, and power transmission equipment. ANSYS Mechanical provides excellent tools to predict and design for the effects of rotordynamics.

In this webinar DRD provides a brief background on rotordynamics and then proceeds to ANSYS rotordynamics demonstrations including normal modes and harmonic response analysis with out of balance loads.  Topics include critical speeds, Campbell Diagrams, and forward and backward whirling modes including ANSYS results animation.

The webinar recording duration is approximately 30 minutes.
