Designating Filling System Issues
Hi there! I am a student using my university's license for Inspire Cast. I have run into the issue when attempting to run casting simulations that my simulation will not progress in the solidification stage. It always completes to ~0.15%, but does not progress beyond that. I have left the program running for over 24 hours…

Stay in Panel after execution?
Hello Community, I am working with HyperMesh 2024.1 and frequently use functions like Align or Project (found in the Topology Ribbon). By default, these tools (panels/guidebars) automatically close after the function is executed. This requires me to constantly re-open the tool if I need to perform the operation multiple…

Issue with Ply Smoothing and Draping in HyperMesh
Hello fellow Altair users and developers, I'm facing some challenges in exporting kinematic drapes of plies within my carbon-composite part. My plies are made of square elements, so they need to be smoothed before being sent to manufacturing. To smooth out their contours, I'm using "Ply Geometry Smoothing", and in the…

How export non-spherical particles in EDEM?
Hi, I want to create a non-spherical bed of particles and use the results as the geometry of my CFD simulation. When I wanted to export my particles via export as stl, the software gave me error that exporting cannot be done for this particle shape. How can I export non-spherical particle shapes as stl file? Thanks.

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…
