Doubts about mbd simulation on fsae models
Hi, i'm a beginner at mbd simulations, and I want to understand some things about motionsolve and the fsae model that altair gives to us. I imported the standard model, but it doesn't match our CAD model, so i'm wondering if there is a way to import our assembly to this model, or even to motionsolve somehow? Or, how can I…

DEM–FEA Coupled Simulation for Granular Packing
Simulating granular packing using DEM and FEA is a powerful way to analyze how granular materials interact with solid structures-especially when both the particle dynamics and the deformability of the structure are important. Coupling DEM and FEA allows for detailed, high-fidelity simulations of granular packing in…

How ro resolve negative volume elements?
Description: Hello. I am working on meshing an assembly of 9 parts using tetrahedral (C3D10) elements on Altair Simlab. I meshed all parts by defining the body mesh controls, creating a surface mesh and then creating a 3D solid tet mesh. I performed the quality check and used Abaqus quality feature, as I want to use this…

Uniaxial Compression of Bulk Material Using Flexible Plate
Uniaxial compression of bulk material using a flexible plate via EDEM-FEA coupling is used for studying how granular or bulk materials behave under vertical compression by a deformable (flexible) structure. The granules are modelled using EDEM, while the compressing plate, enclosed box and punch is modelled as deformable…

Automatic export text file about Model Information
Overview: The script automatically extracts model information (e.g., material, mesh type, mesh count). If the model is not suitable for analysis, it will notify you of any missing or incomplete data. This allows you to verify both the model details and any potential errors. You can also use this simplified information when…

Particle Scale Up Summary Blogs
Computational time has always been one of the most important aspects of DEM Modelling. Initially, it could be assumed that having an accurate and realistic material model through material calibration is the main target. If you want to learn about material calibration, read this post: However, even though calibration is…

Simulating Mud (Limestone + Water) in EDEM
Hello Community, I am working on simulating mud (limestone particles <4mm mixed with water) flowing through a chute using EDEM software. However, I encountered challenges while trying to adjust the material's angle of repose (20 degrees) and its properties. Initially, I created the material using the GEMM Wizard, but I…

Nut Mixing and Packaging System Simulation in EDEM - Material Dosing
A significant proportion of food produced globally is never consumed, with around 14% lost between production and retail [1]. While food loss can occur at various stages of the supply chain, improving bulk material handling in food processing—through virtual testing and system optimization—can help reduce losses and…
