This dynamic event will bring together world renowned thought leaders and industry experts to explore the trends, technologies, and opportunities shaping the future of…
In this window (screenshot) I have pressed the "new sketch"-button and the program says "Select a face or plane as the sketch plane." Where are the planes? Yesterday when I used inspire, they were there. Now they are gone. If I right click on the Global X in the model browser, the program crashes PC specs (if it matters):…
Hello, I have a more or less simple question. Is there a possibility to define the default settings for the Memeber Mesh module? Maybe by using the hm_custom.tcl or a custom extension? Regards Stefan
Good morning, I have an h3d file that I want to visualize in ParaView, but I can't figure out how to use Altair Compose to convert the file to h5 format and load it into ParaView. Additionally, I’m not sure which reader to use within ParaView
I developed a script to setup a simulation and run it with the python API, but I am struggling to run it in batch mode. I copied the code from this post but it does not work for me. When I run it in CMD it just doesn't do anything Here is the code I am using in CMD: "C:\Arquivos de…
非線形材料モデルに、こういう名前のものがあります。rate というのは現象速度のことで、independent ってのは関係ないってことなので、現象速度の効果を考えない塑性ということです。良く分からなければ、単純に塑性ということです。ヘルプに式と出典がありますが、すべての説明がされてるわけでもなく、昔に考えられた式なので出典も入手しずらく、また、同じ理由で日本語の説明も見かけないので、なかなか手ごわいです。自分で行ったテストなどをもとに、なるべく分かりやすく説明して見ます。 上から順に行くとして、σy, σ1 です。σy は初期の降伏応力で、σ1 は最終的に到達可能な最大の応力です。この２つは、まあ良いでしょう。 問題は次の δ です。この…
Hi, I recently downloaded the program and I am experiencing an issue with the OptiStruct license in Altair Inspire Personal Edition and would appreciate any help you can provide. Specifically, when I try to run a topology optimization, an error message appears indicating that a license for Inspire OptiStruct Solver feature…

How is angel used as distance？—operator “Detect Outlier (Distances)”
Hi, I would like to create a simulation of a rigid body floating on the water surface or moving through the water. I'm planning to use the Passive Rigid Body feature for testing. I have currently input the initial velocity and constant speed, but the log file shows the following error: Error: [EIO95] Cannot find/open the…
Dear Altair Community, I am currently working with the PSIM v.2025 IPM nonlinear controller, which requires input data in a .tbl format, as shown in the attached example (Ld_Ldq.tbl). I would like to generate this .tbl file from Altair Flux v.2025 Could you please guide me on how to achieve this? Specifically: Is there a…
hi everyone, someone who could show me how could I apply beams or structural profiles ( c Chanel, pipes, etc) to a line geametry (bus chasis) , I'm trying it in simlab using property, but when I run the simulation, the simulation only recognize the lines, not the structural profiles , please someone who could show me ,…
Why when I enter the length of 315 mm, in the 2023 version, the Air, Runner and Parts on the graph still appear, and the 2025 version does not appear? How to appear in the 2025 version when I enter the length of 315 mm? (All settings are the same in both versions)
Hi, I try to do a 3D tetra (tetrahedral) mesh. I did a mixed mesh on the surface, a 3D tetra mesh on the complex inlet parts and a 3D hexa mesh on the pins and plates. I think I have a few problems in this model. First the bottom surfaces of the pins and the inlet parts (connected to the surface with the mixed mesh) are…
Dear, I have measured gains of all my 16 single elements of my antenna array, where I'd like to use it as the pattern of a directional antenna in ProMan. Here's my thought. My data is in a .csv file, which is not quite able to be converted in to an .ffe file (if there's a way please ignite me), but I managed to convert it…
Hello, ive made some hardware updates on my laptop and i need to deactivate my licence in order to regenerate it Can u help me?
Hello all, I am modeling the pre-tensioning of a bolt in Radioss. To check for slipping, I compare the FT output from the contact interface with FN*static_friction. However, I notice that FT is always lower than FN*static_friction, even though the animations clearly show that the contact is in the slipping phase. I also…
what is the difference between “relative” and “probability” ？
