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.


R19.2 Fluent Meshing Updates and Introduction to ANSYS EnSight (October 2018). This webinar includes presentations and demonstrations of both Fluent meshing updates new at R19.2 as well as the EnSight postprocessor.

Updates to Fluent meshing include a streamlined workflow for watertight CAD and a new volume mesh type called poly-hexcore. The new workflow allows for robust processing of upstream changes allowing users to quickly create a mesh and edit their meshing controls. The Poly-hexcore meshing method uses bulk hexahedral elements with polyhedral elements at the boundaries. Poly-hexcore can provide up to 50% reduced cell count and solve time without sacrificing accuracy.

ANSYS EnSight is a CFD postprocessing tool included with CFD Premium, CFD Enterprise, and CFD PrepPost licences. Added to the ANSYS portfolio in late 2017, EnSight provides significant benefits to large or transient models where other postprocessors can get bogged down.

ANSYS Discovery Live – Instantaneous Simulation Technology (October 2018). This webinar will include a presentation and demonstration of the Discovery Live simulation product first introduced commercially in early 2018. Discovery Live takes advantage of hardware trends by leveraging the hundreds of compute cores available on NVIDIA GPU cards. Recent enhancements to the software at R19.2 have made it more capable and faster than ever.

Built on top of ANSYS SpaceClaim, Discovery Live provides an interactive experience in which you can manipulate geometry, material types or physics inputs, then instantaneously see changes in performance. Discovery Live provides solutions for fluids, structural, thermal, and modal analysis.

ANSYS DesignLife Stress and Strain Calculations (January 2018). DRD conducted this webinar January 31, 2018. This webinar explains how ANSYS DesignLife calculates from ANSYS FEA results the stress and strain values for calculating damage and life.

This is not an introductory webinar for engineers interested in a casual overview of ANSYS DesignLife. Current ANSYS DesignLife users interested in the nitty gritty details of ANSYS DesignLife will find this webinar useful.

This webinar recording is approximately 40 minutes. For a recording of this webinar download here. For the presentation slides please download here. (A password is required if you have not obtained one already. Select DL Stress and Strain Jan 2018 from the password topic list).


Fatigue Life Prediction in ANSYS DesignLife for Mode Superposition Transient Dynamic FEA using Modal Contributors (January 2018). DRD conducted this webinar January 12, 2018, and it is Part 2 of a 2-Part Webinar series on the topic:  Engineering Fatigue Life Prediction in ANSYS DesignLife Using Mode Superposition Transient Dynamic Analysis.

Many ANSYS customers use transient dynamic finite element solutions in combination with ANSYS DesignLife for fatigue life prediction. When this simulation approach is used to model long time duration events such as a vehicle on a proving ground test track, the ANSYS file.rst result files can grow to hundreds of Gigabytes or larger in size. These large result files may make solutions impractical. A clever work around when the desired result is a fatigue life calculation is to avoid writing the file.rst and to use the mode superposition modal contributors in combination with the normal mode finite element results to construct the stress time histories for the fatigue life calculations.

In this webinar DRD shows how to implement this modal contributor method using ANSYS Mechanical and ANSYS DesignLife. DRD provides a practical example and compares the solution times and file sizes for solutions of the same model with and without the modal contributor approach. DRD also provides a hands-on workshop that provides detailed steps he modal contributor method. This presentation lasts approximately 35 minutes.

Fatigue Life Prediction in ANSYS DesignLife for Mode Superposition Transient Dynamic FEA (January 2018). DRD conducted this webinar January 11, 2018, and it is Part 1 of a 2-Part Webinar series on the topic:  Engineering Fatigue Life Prediction in ANSYS DesignLife Using Mode Superposition Transient Dynamic Analysis.

This webinar is the first part in a 2 part webinar series. DRD provides a concise summary of the mode superposition method for transient dynamic analysis and then show how to read this type of ANSYS result into ANSYS DesignLife for fatigue life calculations. DRD also provides an example using a telecommunications rack subjected to the first 10 seconds of the 1940 El Centro, CA earthquake. ANSYS DesignLife is designed to read transient dynamic results from ANSYS Mechanical using the Full Method, and in this webinar DRD provides additional steps required to read results using the Mode Superposition method. This webinar lasts approximately 25 minutes.
