Hello, I have been working through the tutorial ACU-T 6103: AcuSolve–EDEM Bidirectional Coupling with Heat Transfer. In my case, particles are in contact with a hot wall (~600 K), and I would like to include radiative heat transfer effects on the particles. I noticed in the AcuSolve 2026 release notes that a new feature…
I am attempting to import a data file, but need to set custom field lengths as the fields may sometimes be longer than what Monarch (2025.0, 64-bit) is defaulting them to. However, every time I move to a new field, it reverts the previous one to the original default length assigned by Monarch. This is maddening. Is this a…
Hello, I would like to clarify the current availability of the Altair SLC Personal Edition. At the moment, I have downloaded and tested the SLC 2025 engine installer, which appears to allow local usage without requiring Altair Managed Licensing (ALM), effectively behaving like a Personal Edition. However, when testing the…
200mm直径的离心风扇跌落仿真，使用四面体网格建模，四面体单元属性应该如何设置更准确
Hi, I'm looking into the design of a componet subject to strong random vibrations, I read that Optistruct can use the stress response of a random vibration as a constraint in the topology optimization, and can optimize the structure such that the 3 sigma stress stays below a certain limit for the component subject to the…
Hello, My problem statement is that I have to input an f(t) at one end of the waveguide and obtain an integrated poynting power density that looks like where E(w,z) = F(w)* J(z)*g(|r-r'|); and g(|r-r'|) is the green's function, J(z) is the aperture current and F(w) is the frequency spectrum of f(t). Can this be possible in…
I have a chart I am trying to make with the data already stored. the bar chart is correct by the Histogram overlap that I want as a line graph on a second vertical (0% - 100%) on the right can't be found. Any technique to make this chart have two value axis (a second y axis)?
Altair slc native language5 odbc read write text files, summarize and looping with sqlite Note: None of the process queries are supported by the slc 'proc sql' or sas 'proc sql' Note: Character strings are defaulting to 1024 bytes, to fix this you need to define the table attributes explicitly in sqlite. Macro…
Hello everyone, when I try to use OptiStruct in HyperMesh v2022.3, it tells me that it is not installed correctly. It seems that in the Marketplace only the version I mentioned is available. Maybe someone knows how to install the solvers or how to download them so I can install them properly
Bonjour à tous, Nous rencontrons actuellement un problème bloquant sur MotionView lors de la simulation du train avant d'un véhicule. Nous avons configuré un test de Longitudinal Braking et un test de Longitudinal Acceleration. Voici les anomalies constatées : Résultats identiques : Lorsque nous lançons les deux tests…
