From Days to Hours – Rapid Midsurface Meshing and Structural Analysis to Reduce Workflows

By | webinar | One Comment

In finite element analysis, solid geometry of thin structures is commonly idealized as 2D midsurfaces and meshes, but the process is highly elaborate and time consuming. In addition, performing a structural analysis via the Finite Element (FE) method is also a long process often requiring numerous functions, inputs and clicks in existing pre/post processors.

This webinar will briefly discuss streamlined methods to expedite the midsurface creation process. A majority of the presentation will be devoted to how MSC Apex can be used rapidly configure midsurface meshes and perform a structural analysis via the FE method. The webinar will also showcase the integration of solid and shell elements via MSC Apex “glue” technology to quickly integrate a “bulky” solid section into an existing midsurface mesh.

10x Faster Midsurface Modeling and Meshing for Automotive Trim Components

By | webinar | No Comments

The process of creating midsurface geometry and finite element meshes of automotive trim components such as head liners, consoles, and door trims can require extracting dozens of planar and curved midsurfaces, adjoining specific free edges, meshing, and more. Unfortunately with existing finite element pre/post processors, the process can require multiple days to complete.

This presentation discusses optimal methods and CAE software available to reduce the time needed to create midsurface models and meshes. The topics discussed can expedite the process up to 10x. A live demonstration will be performed on an automotive interior console and will be used to highlight the time savings gained from implementing the concepts and CAE technology discussed in this presentation. The use of MSC Apex will be highlighted throughout this presentation.

Midsurface Extraction and Meshing of Thin Structures – 10x faster with MSC Apex

By | webinar | No Comments

A common practice for finite element analysis of thin structures involves abstraction of 3D solid geometry into 2D midsurface representations. The midsurface representation is then meshed with 2D elements such as shell, membrane or plate finite elements. While the midsurface method for thin structures has been used for a long time, existing methods and software requires users to devote hours or days to the process. As thin structures grow increasingly complex, i.e. varying thicknesses and steps, multiple stiffening webs, features, etc., analysts are devoting increasingly more time to constructing midsurface models and less time on engineering analysis.

This webinar presents the latest methods for expediting the process of midsurface model creation and meshing. The midsurface methods mentioned in the webinar will be demonstrated live with the use of MSC Apex.

Rapid Midsurface and FEM Modeling Techniques for Automotive Trim Components

By | webinar | No Comments

Many automotive interior trim components such as headliners, door trim, and consoles are characterized as thin structures that can be difficult to model. The process of performing a structural analysis on such trim components via Finite Element Analysis often requires the creation of midsurface geometry and meshes for very complex, curved, variable-thickness sections. Unfortunately with existing finite element pre/post processors, creating the midsurface geometry and mesh can require anywhere from a few hours to days, depending on the complexity of the model, and the limitations of the software being used.

This presentation covers the newest methods and CAE technologies available to expedite the midsurface geometry and meshing process up to ten times faster (10x). An actual midsurface and meshing demonstration will be performed on an automotive headliner and best practices will be discussed to expedite the process. The use of MSC Apex will be highlighted throughout this presentation.

FEA, Solving & Post-Processing Assemblies Using MSC Apex Structures

By | webinar | No Comments

This presentation discusses best practices for expediting the midsurface geometry process. Specifically, a new semi-automatic or incremental method for creating midsurface geometry will be presented. The concepts mentioned in the presentation will be demonstrated on an injection molded plastic component. The same component required 10 hours to complete with existing pre/post processors, but once the incremental midsurface method is adopted, the process required 1 hour. The MSC Apex incremental midsurface method will be used throughout the live demonstration.

Constructing midsurface geometry and meshes for Finite Element Analysis (FEA) is a process often requiring hours to days to complete. Existing midsurface extraction methods in pre/post processors, while automated, often produce very incomplete midsurface geometry. As a consequence, significantly more time is required before midsurface geometry is completed and meshed.

New Methods to Update Finite Element Meshes Rapidly

By | webinar | No Comments

This presentation discusses modern methods to update existing FEM models significantly faster than before. The methods discussed are applicable to thin structures that can be readily represented as shell FE meshes. The specialized meshing capabilities of MSC Apex will be highlighted and demonstrated on a sample part.

A finite element mesh may be modified dozens of time throughout its life. If performing a detailed stress analysis, the addition or modification of the smallest detail will require substantial remeshing. For loads groups, the detailed FEM model will be simplified significantly. If a repair of a part after its in service is being considered, the original FE mesh has to be updated to reflect the revised design. In a majority of cases, every additional change to the FEM requires substantially more time and work to edit and mesh geometry. Considering the need to deliver FEA results in a timely manner, quick methods to update FE meshes are necessary.

Expediting the process of TET meshing highly complex solid geometry for FEA

By | webinar | No Comments

This presentation discusses common causes that render solid geometry unmeshable and tactics to identify, resolve, and simplify solid geometry for tetrahedral meshing. MSC Apex, a specialized direct modeling and meshing solution, will be demonstrated live and applied to a real world example. Ultimately, the solutions mentioned in this presentation can reduce your tetrahedral meshing process from days to hours.

Meshing solid geometry with tetrahedral elements is a quick way of creating finite element models, but is not without its challenges. In some cases, solid geometry cannot be successfully meshed by the most advanced tetrahedral mesher. In many other cases, a tetrahedral mesh is produced, but is composed of poorly distorted elements that are inadequate for finite element analysis. The reason for many of these challenges has to do with highly complex solid geometry that is essentially in a state not friendly for a tetrahedral mesher. Complexities of solid geometry can include features, small solid faces, short edges, and other details. While many pre/post processors have sophisticated meshing functions, many lack effective geometry modification tools necessary to resolve these complexities so as to make solid geometry more TET mesh friendly.

By | webinar | No Comments

The Direct Modeling and Meshing methods in MSC Apex can expedite the geometry modification and meshing workflow. Like any new tool, if not properly used, it is still possible to generate problem geometry or arrive at situations where substantial rework to the geometry is needed before moving to a mesh. In order for new tools to be used effectively, best practices must be known.

This webinar will go through a few examples that highlight tool usage techniques and options plus model tactics to improve your workflow efficiency. Often seeing a 5 second example can save you another few minutes of work.
