How to Completely Clear Bottom-Left Prompt Messages in HyperMesh GUI?
Hi everyone, I've observed that after executing some custom TCL scripts in HyperMesh, a prompt message remains displayed at the bottom-left corner of the GUI. Commands like *clearmarkall and hm_clearall do not completely eliminate these prompts. Does anyone have experience with this or know any alternative methods or…

How to create this node?
I learn a tutorial named rubber ring. I open this model and find there is a node 2266 not in the corner of elements but on the edges. I am curious how to create a node anywhere I want. I use 'point' in 'topology' to create a point, but it can not be recognized as a node. It's just a geometry point not a part of FE model. I…

Freezes and lags in HyperMesh v2025 and v2024.1
Hello, I'm experimenting lags in HyperMesh on my DELL Precision 3490 (specifications in the linked image). Whenever I want to zoom, move or rotate my models, the software freezes for a couple of seconds before I can actually inspect it, and then I get to see like one image per second of me moving it. I checked in my task…

CFD INSPIRE PROBLEM
Hello everyone, I'm having convergence problems with altair inspire. I set up a cfd simulation using a cylindrical domain, imposing 7bar at inlet and 1 atm as outlet (at 1m far) but the simulation does not converge. I was thinking maybe it is due to air compressibility happening or supersonic flow maybe. (7 bar is in fact…

Issue with K&C Steering Analysis – Unable to Get Results Without Explicit Motion in MotionView 2024.
Hello Altair Team, I am currently working on a Kinematics & Compliance (K&C) Steering Analysis in MotionView 2024.1. I have configured the K&C setup properly and selected the Steering test. However, I am facing the following issue: When I run the analysis without defining any explicit Motion entity (expecting the K&C…

How to set the braking torque from the front and rear axles to the four wheels separately?
Hi ~ I use Vehicle Tools of MotionView 2022.2.1, and the Model Type is Car/Small truck. In Objects Disk Brakes, the brake torque is divided into front brakes and rear brakes. Since the default is left-right symmetry, the brake torque of the left and right front wheels will be the same, and the brake torque of the left and…

Azham
Hi everyone, right now i'm trying to simulate torque based on the dq current of a pmsm with inner rotor and 3ph. so far i have done it in flux motor and exported it into flux. However, i do not know how to plot or control the torque depending on the dq current as the parameter is not there. Should i use macros or just…

OptiStruct CONTACT Setting – FREEZE + ADJUST=AUTO not closing gap
I have a question regarding the proper CONTACT setup for modeling surfaces that are fully bonded with no initial gap. In previous cases, I was advised to include a small clearance (e.g., 0.01 mm) between components to avoid convergence issues due to nodes being too close. However, in my current model, the physical assembly…

some questions about contact
I use contact/group in hypermesh 2024.1. I don't know differences among this four types('stick' 'slide' 'freeze' and 'auto') , especially 'auto'. And what is 'morient' meaning and this four types meaning? which items are necessary and strongly required and the other remaining default? Is there any tutorial I can refer to?
