A space for simulation related technical resources and discussions.
Evaluating connections between components is crucial for design analysis in engineering. This challenge spans various domains, including welds, electrical components, adhesives, snap fits, and more. While multibody analysis can be used to validate these connections, incorporating flexible bodies into the analysis can…
MotionView provides several advanced component mode synthesis (CMS) methods for structural analysis: Craig Bampton, Craig Bampton with Geometric Stiffness, Craig Chang, and Craig Chang with Contact. * Craig Bampton Method: This technique involves computing mode shapes by applying unit displacements at each interface node…
Complex tool movements are essential in various applications, including swept friction stir spot welding. This article focuses on the practical application of tool movement in this welding technique. Solutions used: Altair Radioss and HyperWorks 2022.3. For more information, please, download the Presentation and Model &…
This article demonstrates how to use Includes, Submodels, and Transformations to manage the position of a Cellphone for a drop test load case. Please, refer to the Presentation and Models & Results for more details.
Ensuring an accurate representation of bolts in Finite Element Analysis holds significant importance in obtaining reliable structural simulations. Bolts play a critical role in connecting various components within a structure, transmitting loads, and maintaining stability. An improper representation can lead to inaccurate…
This article aims to demonstrate how Altair Radioss is used to simulate a Picture Frame test. This test is used to evaluate in-plane shear characteristics of fabric material, such as shear modulus and fiber locking angle. The test consists of a squared specimen held by clamps on all four edges, pin-connected at their ends,…
When it comes to metal or plastic damage, /FAIL/JOHNSON is a widely used, efficient failure model. This failure model uses a nonlinear, plastic strain-based, failure criteria with linear damage accumulation. The aim of this knowledge base article is to share an excel sheet that will allow users to visualize the failure…
In this blog, we will explore the power of the Inspire Sketching Module. With Inspire’s Sketch API, you can create, manipulate, and refine 2D sketches, which form the foundation for many 3D modeling operations. Sketching is a fundamental step for designing intricate shapes, structures, and models. Let's dive into key…
Transfer chutes are present in many mining operations, some with hundreds of transfer chutes per plant. There are many configurations and sizes of transfer chute however the main purpose is to transfer material from belt to belt or from belt to bin or processing plant. With Altair® EDEM™ we can design and optimise the…
Radioss simulations which include Fluid-Structure Interaction with ALE formulation may stop with an error message indicating a negative or zero density issue, such as the following : MESSAGE ID : 167 ** STOP: NEGATIVE RHO=-1.4673475693963E-07 FOR 3D-ELEMENT ID=2882209 ERROR TERMINATION This may be due to multiple causes…
