Detailed Descriptions of DRD's SpaceClaim Course Workshops
DRD SpaceClaim Workshop 1 - Simplification of Cast Part for Stress Analysis
In this workshop we read geometry into SpaceClaim, cut it in half to take advantage of symmetry, remove unnecessary features, split a surface for load application, and transfer the model into ANSYS Mechanical to perform a Static Structural analysis.
DRD SpaceClaim Workshop 2 – Slicing a Part for Brick Meshing
This workshop demonstrates some of the techniques available within SpaceClaim for slicing geometry to obtain a brick mesh. The node count can be drastically reduced to save on disk space and solve time when switching from tetrahedron to brick elements.
DRD SpaceClaim Workshop 3 – Creation of an Automobile Chassis Assembly Shell Model
In this workshop we read 3D solid geometry into SpaceClaim, then extract midsurfaces to mesh it with shell elements in ANSYS Mechanical. This workshop also demonstrates how to extend surfaces and share topology to create a multibody part, which will allow for a conformal mesh between bodies, eliminating the need for contact.
DRD SpaceClaim Workshop 4 - Creation of a 2D Axisymmetric Finite Element Model from a 3D Threaded Connection Assembly with Helical Threads
This workshop shows how to make 2D axisymmetric models from 3D geometry. This model is particularly interesting because it demonstrates the process of making a 2D axisymmetric model of a threaded connection, which is not truly axisymmetric due to the helical thread geometry.
The assumption that helical threads are axisymmetric is a well-accepted assumption for threaded connection finite element analysis. The size of the model (number of nodes) is drastically reduced in this process, leading to a faster time-to-results and more design iterations. This axisymmetric simplification can be a good first step for many types of models that have rotational symmetry.
DRD would like to thank Baker Hughes of Claremore, OK for providing the geometry for this tutorial.
DRD SpaceClaim Workshop 5 - Creation of a Beam and Shell Model from Solid CAD Geometry
This workshop demonstrates taking a full 3D solid CAD model and converting it to line bodies and surfaces, to facilitate beam and shell element meshing for analysis. This process reduces the complexity of the geometry, which lowers the computational resources needed to solve this problem, while still allowing engineers to make design decisions from the simulation results.
DRD SpaceClaim Workshop 6 – Parametric Updating of a 3D Fluid End Assembly Using SpaceClaim
This workshop demonstrates the creation and use of a simple 3D geometric parameter in SpaceClaim to drive a structural simulation in ANSYS Mechanical. The user provides a range of parameter values for the simulation to determine peak stress in the discharge flange to optimize its thickness.
DRD SpaceClaim Workshop 7 – Parametric Updating of a 2D Axisymmetric Threaded Connection Assembly Using SpaceClaim
This workshop demonstrates the creation and use of the detail annotation dimension parameters feature in SpaceClaim to drive a structural simulation in ANSYS Mechanical. The user provides a range of parameter values for the simulation to determine peak stress in the collar to optimize the radius.
DRD SpaceClaim Workshop 8 – Optimized Geometry Cleanup with Extract and Fit Curve Tools
This workshop demonstrates some of the automated tools that can be used to cleanup STL geometry from ANSYS Mechanical’s Topology Optimization analysis. Extract Curves and Fit Curves provide easy options for taking non-CAD geometry, which is commonly dirty surfaces, and turning it into smooth CAD surfaces.
DRD SpaceClaim Workshop 9 – Optimized Geometry Cleanup with Automated Facet Tools
This workshop demonstrates some of the automated tools that can be used to cleanup STL geometry from ANSYS Mechanical’s Topology Optimization analysis. Basic facetted geometry conversion, curve extraction and curve fitting are used to create CAD geometry from STL geometry. A special meshing technique is then used to smooth over any facetted surfaces in ANSYS Mechanical.
DRD SpaceClaim Workshop 10 – Optimized Geometry Cleanup with Manual Facet Tools
This workshop demonstrates some of the manual tools that can be used to cleanup STL geometry from ANSYS Mechanical’s Topology Optimization analysis. The primary tools in ANSYS SpaceClaim demonstrated in this workshop include surface extraction and surface skinning. This, combined with a few automated tools like Shrinkwrap, provide nice, smooth CAD surfaces as a result.
DRD SpaceClaim Workshop A-1: Creating Fluid Domain Geometry
This workshop demonstrates extracting the internal volume of a plunger-box assembly for Computational Fluid Dynamics analysis, using SpaceClaim’s Volume Extract tool.
DRD SpaceClaim Workshop A-2: Creating a Fluid Domain from Multiple Mesh Sources
This workshop demonstrates extracting the internal volume of a control valve assembly for Computational Fluid Dynamics analysis, using SpaceClaim’s Volume Extract tool. This workshop also demonstrates sectioning the flow domain and creating a multibody part to facilitate hex meshing in ANSYS Workbench Meshing.
Supplementary SpaceClaim Workshops from ANSYS, Inc.
ANSYS Workshops 1 & 2 - Using the sketcher
In this pair of workshops we introduce the user to the sketching functionalities in SpaceClaim. Both workshops involve creating geometry from scratch.
ANSYS Workshop 3 - Advanced 3D Modeling concepts
In this workshop additional geometry is created from scratch using various sweeping, blending, and revolving techniques.
ANSYS Workshops 4 & 5. Geometry Repair
These workshops cover repairing geometry. Repair includes stitching open surface geometries to mold into a single surface body, detecting missing faces, sewing to remove gaps/openings, and ultimately accomplishing solidification of the problematic geometry. The workshops also cover removing interference between parts.
ANSYS Workshop 6 - Spot Welds and Instances
This workshop takes pre-existing geometry and adds weld connections.
ANSYS Workshop 7 - Fluid Domain Extraction
The geometries provided for this workshop cover fluid domain creation for both external and internal flows.
Workshop 8 - Beam and Shell Modeling Techniques
Multiple geometries are provided in this workshop for the user to gain experience extracting shell surfaces and beams and connecting them together to create efficient analysis models.
Workshop 9 - Parameterization of a Mixing Tank
In this workshop we create a mixing tank with parameters to be fed into ANSYS Mechanical for a design study.
