Detailed Descriptions of DRD's DesignModeler Course Workshops
DRD Workshop 1a - Simplification of a Cast Part for Analysis in ANSYS Mechanical
In this workshop we read geometry, cut it in half to take advantage of symmetry, suppress unneeded features, split surfaces for load application, and transfer the model into ANSYS Mechanical for later analysis.
DRD Workshop 1b - Defining Planes at the Desired Location and Orientation
In this workshop we create planes a couple of different ways to explain location and orientation of sketch planes (which may later be used as coordinate systems in Mechanical).
DRD Workshops 2a. Geometry Simplification of a Grease Seal Assembly
In this workshop we demonstrate the need for the freeze/unfreeze functionality while simplifying the assembly through feature suppression and sketching.
DRD Workshop 2b - Transfer of DM Coordinate Systems to Mechanical
Brief workshop that covers transferring coordinate systems to Mechanical and later used as reference for a point mass.
DRD Workshop 3a - Slicing of a Bolt for Efficient Meshing
The workshop demonstrates the large advantage of using brick elements over tetrahedron elements for large models. The node count can be drastically reduced to save on disk space and solve time when switching from tetrahedrons to bricks..
DRD Workshop 3b through 3d - Brick Meshing of a Block with Perpendicular Through Holes, Non-Axisymmetric Disc, and PWB with Fastener Through Holes
These three workshops demonstrate different techniques for slicing geometry within DesignModeler to get the desirable brick elements. These do not have specific instructor demonstrations to go with them, but, they allow the students to work through them to develop expertise at the procedure.
DRD Workshop 4 - DesignModeler and DesignXplorer Optimization of a Valve Bonnet
In this workshop we read a SAT file into DesignModeler, which produces a static model without parameters or intelligence. We use DesignModeler to convert the portion of the model to be optimized into parametric geometry. In Mechanical we perform analysis and manual design optimization using the newly created parameters. The students then perform a ‘what-if’ series of simulations using the Design of Experiments capability of Workbench.
DRD Workshop 5 - 2D Model Extraction from Full Model of Grease Seal Assembly
In this workshop we take a full 360 degree model and extract the 2D surface such that it lies in the correct X-Y plane orientation for subsequent 2D axisymmetric analysis in Mechanical.
DRD Workshop 6 - Creation of a Fluid Domain for CFD
This workshop extracts a 3D fluid domain from pre-existing geometry using the 'Fill' tool and boolean operations.
DRD Workshop 7 - Midsurface Extraction, Extension, and Shell Modeling of a Sheetmetal Assembly
A first introduction to creating surface geometry in DesignModeler, this workshop shows students how to extract mid-surfaces and create Surface Extensions to tie this three part assembly together, without the need for contact regions in Mechanical.
DRD Workshop 8 - Surface Extensions: Alternative Method to Beam Spiders
We show the students how to take a sheet metal assembly that may have previously been connected with an older beam spider method and demonstrate using Surface Extensions and Mid-Surfacing in DesignModeler to tie the parts together without needing beam spiders. The Surface Extension method creates physical geometry in the Mechanical model.
DRD Workshop 9 - Shell Modeling of a Platform Assembly including Midsurface Extraction and Extension, Stitch Weld Creation, and Split Surfaces for Parametric Load Application
Following the previous two workshops, we extract surface geometry from solid geometry, demonstrate creating stitch welds between a support tube and the platform, and set up a surface for load application that we can parameterize. We then set up the analysis in Mechanical and solve the model.
DRD Workshop 10 - Brief Orientation of DesignModeler for Users with No CAD System
This workshop leads the user through creating a model from scratch and getting familiar with the sketcher. It could be the first workshop to do for those students who do not have access to CAD at their company.
DRD Workshop 11 - Analysis of a Sheetmetal Pan Including Corner Spot Welds and Edge to Edge Contact
This workshop creates geometry from scratch in DesignModeler using a variety of modeling and sketching features to build the user's experience level.
DRD Workshop 12 - Beam Modeling of a Flight Simulator Platform
In this workshop, we create a flight simulator base from scratch, using line body geometry and cross sections assigned to the various parts in the model within DesignModeler. We transfer the geometry into Mechanical, where it meshes line body geometry with beam elements. Post-processing is then carried out after the model solves, exposing students to the Beam Tool result object.
DRD Workshop 13 - Creation of a Hemispherical Tank with Doubler Plates around Opening
In this workshop we create a tank with doubler plates and reinforcing ring from scratch.
