Error in coupling Flux with Matlab-Simulink
I want to couple a Flux v.2025 project with Matlab/Simulink v.2023b. First, I got a .F2MS file from Flux, then I opened Matlab from the Flux Supervisor, and then I selected Flux Link block in Simulink library. Although the time step is the same in the two the softwares, I face the below errors: Error:An error occurred…

Error 2150
Hey, I am just learning optistruct, 1 week in. I'm doing a topology optimization for a steel bridge competition, where the aggregate deflection needs to be less than 0.75 inches, the weight of the structure is less than 250lbs, and the sway is less than 0.25 inches. I am having trouble with error 2150. The model on…

Accessing Statistically-Based Design-Allowable Properties Using MMPDS Data in AMDC
In finite element analysis (FEA), the accuracy of your simulation is only as good as the input data - particularly the material properties. In safety-critical applications such as aerospace, defense, and automotive, using nominal or average material properties is not enough. These values don’t account for natural…

Is it possible to incorporate the impact of endwinding in 2D Flux thermal study?
I am performing a 2D radial-plane thermal simulation of an electric machine. Normally, the effect of the end-windings is neglected in this study, as it is not modeled. Is there any way to include or approximate the impact of the end-windings in such a model? Is there any way to add a thermal circuit to model it? For…

What is the difference between circuits constructed through "Wires" and "Cables"?
Description: Recently I have found out that in CADFEKO there exists an extension called "Cables" (Home > Extension > Cables) through which I seem to be able to construct circuits. Up until now I have mainly constructed circuits I was interested in directly by using Wires and Loads. I am curious whether there are difference…

Particles disappear
Hi, I am doing a simulation of a ramp that vibrates and has particles. The issue I am having is that when the ramp starts to vibrate, after 0.05s the particles disappear. I have tried reducing the Rayleigh Timestep/ Percentage, but this keeps happening. Is there any other reason why particles might be disappearing and how…

Hypermesh Python API: Getting elements by config
Hi, I'm wondering what the best way is to collect elements by type in the python API. I found how to collect all elements but I only want shells really which I can then feed into the next part of the script (creating a display model from a set of shells is the ultimate goal). Looking at the examples, it seems to suggest I…
