Hello everyone, I am currently working on an FSI (Fluid-Structure Interaction) analysis using Optistruct and Acusolve with a student license, both running version 2022.3. The analysis is a basic "flow over a plate" model that I am using for training purposes. As such, I have created simplified models for both the…
Hi everyone, As shown in picture. I try to simulate for modal analysis but i cannot solve since the model contain "low relative volume" part. But i cannot remove this part as it is crucial part of the structure as it is one of the main structure for roof and AC unit installation. Please suggest how to solve this problem.…
The device that originally received license authentication is broken and I want to receive license authentication on a new device. How do I resolve this?
Using CFD-DEM coupling, should the diameter in the material settings in CFD be the same as the particle diameter in EDEM?
Which C standard is considered in code generation/C block? I can't find in the documentation which C standard is considered valid by the SimCoder C block (SimCoder version 2022d0.61). For instance: * In the C89 standard there is no comment using "//" (but in the generated code we have them) * In the C99 standard we can…
Hello, I am trying to do a Non linear transient simulation on a sheet metal that contacts a rigid mesh only with gravity loading. The sheet metal seems to be moving in the right direction and contacts the part correctly, but once it has contact with the rigid mesh it moves upward and even though the solution converges, the…
Luego de la Instalación del programa Altair Inspire, el programa se cierra y no inicia; se ha realizado la autorización de la maquina y se ha agregado la clave de licencia.
Hello, I am running a SimLab automation with a batch script. I import a specific user settings file with the SL_USER_DEFINED_SYSTEM_SETTING_FILE environment variable. However, I have issues with my script and I think it is related to the user settings I defined. Is there a way to check the values of the user settings used…
i am applying contact stick , discrete-Surface to surface, . in Hyperview It will penetrate . pls find attached out file , give me solution .
I have a composite part that I'd like to optimize. The base ply structure is a standard 0°/45°/90°/-45°/0°-stack. I want to optimize this part and reduce the plies in areas where they're not structurally necessary. The first ply should however not be optimized to get a uniform surface of the part, so only the remaining…
