Type 3 Controller Optimization with PSIM and HyperStudy
In this article we will explain how to set up the optimization of a Type 3 Controller with PSIM and HyperStudy. The first thing we need to do is to define our variables (inputs) and goals for the optimization so that we can set them in HyperStudy later: Optimization Inputs The optimization inputs are the variables which…

DOE and Optimisation
Hello, I'm trying to run an optimisation within a DOE under Hyperstudy/Hypermesh. Initially I've tried running the optimisation inside the DOE tool under Hypermesh but that was giving me way too many runs (I believe it was creating a run for each iteration of my variable, which was not exactly what I wanted) I ran an…

Improving Prosthetic Knee Performance using Inspire Motion
INTRODUCTIONProsthetic knees have seen significant improvements over the last several decades. Originally, single axis prosthetic knees helped amputees to walk again. However, they lacked the stability and range of motion of real knees while requiring an unnatural gait. The polycentric knee was developed to address these…

Output Response for specific component in Hyperstudy
Hello, I would like to investigate the system behavior of a Hypermesh model in Hyperstudy. The FE model consists of various components or assemblies. I have parameterized the .fem file and performed a nominal run. Now, I would like to use the .h3d file to output the maximum stress for specific components or assemblies.…

Meshing Irregular 3D Shape with Hexahedral Elements Only
Hello everyone, I am using HyperMesh 2024 to mesh a biological tissue with an irregular 3D shape. I know it’s fairly easy to generate a voxel mesh from medical images, but the boundary ends up with a step-like, unsmooth appearance. To solve this, I used a custom code employing the marching cubes algorithm, which provided…

Clarification about SimSolid and Optimization
So, an interesting issue came across my desk today, that I felt was important enough to clarify with a post here in the Community. It was recently brought to my attention that there was a misconception about Topological Optimization within Inspire and the use of the SimSolid solver. Someone recently set the Analysis Solver…

Using Radiated Sound (RADSND) in Optimizations
Hello, I am working on utilizing the radiated sound method of external acoustic sound pressure measurements in hypermesh, and want to use this response output in optimizations. The standard outputs for responses in optimization do not directly point to acoustic pressure, but since this is a frf response technically, would…

DOBJREF definition
Hello, I'm trying to set up a MAXMIN optimisation and I want to use DOBJREF. I tried to define two references in HM2023 to point to 2 different responses with the same DOBJREF and HM doesn't agree with me - it says New entity id conflicts with existing id. I found this in the help file for DOBJREF: " The same DOID can be…
