Hello, I am attempting to simulate the operating mechanism of an internal combustion engine in order to investigate the influence of engine-induced vibrations on the components mounted to it. The simulation framework is organized into simplified blocks, as shown in the attached figure. The engine is modeled as an inline…

Overview This project presents the Altair solutions for Air Burst Explosions. This project includes: * 2 ready-to-use Altair Radioss models* Altair Radioss version is V2022.3 * The Unit System is in g, mm, ms, MPa * First model is a 2D-axisymetrical model. This model is automated to be adaptated to a wide range of threat…
Overview: Hello everyone, I am currently performing numerical simulations of explosion in air using both Altair RADIOSS and ANSYS AUTODYN, and I am observing significant discrepancies in pressure results between the two solvers, despite using nominally identical input parameters. I would greatly appreciate insights from…
I am an undergraduate civil engineering student and want to do structure analysis for my dissertation. Research Topic: Structural Robustness of Existing Buildings through Retrofitting.
I am currently using the free trial license for hypermesh and optistruct. How do I update the trial license to the license that my company has access to? Is there a number to call to help answer questions like this?
The input value of isens is always 0. I took the derivative of the first-type response (rparam) with respect to the output of the third-type response (rresp) and got dresp, but it doesn't seem to have any effect, and the computation time is the same as using the finite difference method. I hope to get everyone's help.…
Hello, I am looking to create a custom constraint to place a lower bound on the number of nodes a ply can have after Freesize optimization. My first attempt at this was to run the optimization once as normal. Then create a new response that passes in the nodes from the ply I'm looking to constrain. This response would then…
After repeatedly reinstalling and activating Feko to fix an error, it seems I exceeded the activation limit, and now I can no longer deactivate it as shown below. I want to reset the activation limit count. How can I do this?
Currently, I have a student license activated on my old laptop. What is the procedure to activate the license in a new laptop instead of the old one? Thank you!!
Hello Altair Community, I will be working on a 3-wheeled sidecar design where the side wheel is also steerable. I need to build the model from scratch for a multibody simulation in MotionSolve, and this is my first project of this type, so I’m unsure about the best place to start. I already have the main kinematic points…
