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…

huge temporary files
Hello Altair Communuity, I built a large finite element (FE) model and want to evaluate the stresses in the components. The problem is that HyperWorks creates a large number of temporary files during the calculation, which causes the calculation to break down when only a few elements are output (less than 100,000). If the…
