Meshing the fuselage - wing Area
When merging meshes from two components (e.g., wing–fuselage junction), what are the best practices to ensure a proper connection? How should differences in mesh resolution be handled (e.g., finer mesh on the wing than on the fuselage)? Is it problematic to have highly stretched or anisotropic cells in this region? (like…

Issue with defining Johnson-Cook damage (D1–D5) in HyperMesh 2025 LS-DYNA interface
Hello everyone, I am setting up an impact simulation in HyperMesh 2025 using the LS-DYNA profile. I am working with the Johnson-Cook material model (*MAT_015) and I want to define a complete failure model using the Johnson-Cook damage parameters (D1–D5) via *MAT_ADD_EROSION. However, I am running into an issue: In the…

Rotor / hub meshing best practise
Hello, What are the best practices for modeling the rotor hub–blade connection in transient simulations? Should a gap be introduced between the blades and the hub? Is it preferable to remove the hub entirely? Or should a gap be defined between the hub and the fixed geometry while allowing the hub to rotate? Thanks !

Urgent: Issue with activating an studen edition licence
Hi, I previously used AI Studio in 2024 with a student licence, which expired in 2025. I now need to use it again for my university course, but I’m having an issue activating the student licence. I have generated a new student licence key and downloaded AI Studio version 2026.0.5 (previously I was using version 2025.0.1).…

Question about a post regarding MotionView coupling with EDEM and Inspire in the community.
This post explains using Inspire to parameterize the geometry, then importing the parameterized model into EDEM, and finally coupling it with HyperStudy. I understand all the steps up to this point. However, I’m confused about the part where the parameterized geometry is imported into EDEM and then coupled with MotionView.…

.h3d file and .force file correlation
Hi, I just wanted to confirm exactly what results the .force file presented compared to visualising the results in a .h3d via Hyperview? For example, I was under the impression that if you gave an element a defined MCID that this is what the .force output file would generate results with respect to. However, when I check…

Roll Center Height and lateral Displacement calculations
Hello, For my rear suspension, I have a pure trailing arm setup. I used the semi-trailing arm template and modified it by deleting the toe link and making the trailing bushings parallel to each other, according to the geometry, the roll center height should be zero should lie on the ground plane but according to the…

S-Foundation - Surcharge Load
Hello, If I am adding 142kPa Surcharge Load in model as Tank load on Mat Foundation, why my Soil bearing capacity demand is 3-4 times more than total downward surcharge load + self wt of pad. When I am applying load as point load in centre instead of surcharge load my soil bearing check is ok.

Student Licence - was already activated using different HostIDs.
Hello, I have connected to my laptop and then deinstalled the programm without deactivating the licence. Now I want to install it on a more powerful PC and I can not activate the program as it says that the licence was already used by a different HostID. How can I reactivate my licence?

Relaunch simulation with some additional frequency points
Hello, I have a simulation which I run with let say 5 frequency points. I want to rerun the simulation with 10 frequency points, but without having FEKO to resimulate the 5 frequencies I've already simulated. Is there any way to do so ? I've tried simply simulating, adding frequency to the frequency list ("List of discrete…
