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…

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…

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…
