Is there an API version of the Edinburgh Elasto-Plastic-Adhesion (EEPA) Contact Model available?
Hello there, I am searching for an API version of the Edinburgh Elasto-Plastic-Adhesion Contact Model. I would like to customize some parameters (especially the friction parameters, such as the friction coefficient depending on velocity or normal force) in order to achieve a better fit of a soil model to the measured data.…

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…

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…

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…

Type 3 Controller Optimization - Part 1
In this article we will explain how to set up the optimization of a Type 3 Controller with PSIM and HyperStudy. Note: Part 2 has been uploaded and adds Phase Margin and Crossover Frequency to the optimization. The first thing we need to do is to define our variables (inputs) and goals for the optimization so that we can…
