Split 기능 활용하기 1편 Split 기능은 원하는 부위를 여러 가지 entity를 이용하여 자르는 기능입니다. 이번 시간에는 Interactive, Nodes, Lines을 활용하여 관심부위를 자를 방법에 대해 알아보겠습니다. 1) Interactive Mode * Surface 위에 point 정보를 추가/제거 가능 * point 점을 이어서 surface line 정보 생성 가능 [line 생성 전, point 점을 이어 line 정보 생성] [line 생성 후, line 기준으로 surface가 split] 2) Node Mode * Element의 node 점을…
*ELEMENT_SEATBELT_PRETENSIONER and *ELEMENT_SEATBELT_RETRACTOR LS-Dyna keywords can be converted into one Radioss Keyword: /RETRACTOR/SPRING. /RETRACTOR/SPRING contains information used to define both a pretensioner element and a retractor element. See attached slides for more details and example.
The layer mesh technique is highly beneficial for meshing the skin depth in solid conductor regions. This video demonstrates how to create and assign layer mesh for volumes. It also illustrates how to display volume mesh elements within volumes.
The eLearning course, Altair romAI eLearning, is now available on learn.altair.com! Altair® romAI™ is a game-changing artificial intelligence (AI)-powered technology within Altair® Twin Activate™. Leveraging ROMs for system evaluation speeds up computationally expensive simulations, such as discrete element method (DEM),…
This article explains about how to switch from current source to voltage source excitation for a star-connected PMSM motor. The idea is to plot the voltage of phase_1 current source from the current source driven model and check at what position of the rotor, the voltage is maximum. Then in the voltage source-driven model,…
Let’s have a look at the key features and improvements of Altair® Flux® 2023.1 What if you could let the software guide you towards optimal shapes of your electromagnetic devices without any need of parametrization of the geometry? This was already possible by using free-shape optimization. Flux 2023.1 version provides…
PSIM stands as a dynamic platform for power system simulations, offering users the capability to create custom mathematical functions for a range of applications. In this article, we'll explore the versatility of PSIM in electric machine mathematical models, using DC machine modeling as just one illustrative example. This…
Radioss offers the capability to store the deformed mesh and its corresponding material state between different simulations. This feature gives an excellent flexibility in multi-stage simulations, such as: * Considering the manufacturing process into a crash simulation * Consecutive drop test simulations * Dummy and seat…
When it comes to metal or plastic damage, BIQUAD is a widely used, efficient and userfriendly failure model. This criteria is available in OptiStuct for Explicit Analysis since version 2023. This failure model uses a simplified stress triaxiality & plastic strain-based, failure criteria with linear damage accumulation. The…
