How to extract global moments of inertia and calculate impulses
Hi all, I'm looking at trying to extract impulses from bodies in a MBD model. For linear impulses this is relatively trivial but for angular impulses the need to compute the inertia tensor makes this more difficult. Currently bodies are defined with inertias given in a global coordinate system not the cm. I assume the…

always_comb implicit sensitivity list
It seems that dsim includes in the implicit sensitivity list of always_comb the variables declared within the block . Consider the following simple code (I know that using nonblocking assignments in always_comb is not recommended, hower it is also not prohibited): `timescale 1ns/1ps module test; logic a,b, y; always_comb…

Hypermesh CFD hexa mesh 생성 관련
Description: 첨부한 링크의 방식처럼 hexa mesh를 구성하고 싶은데 CFD 프로그램에서는 어떤 기능으로 생성을 할 수 있는지 알고 싶습니다. Extrusion으로 할 경우 mixed 되어 있어서 기능이 활성화 되지 않는 상황입니다. https://community.altair.com/discussion/63977/extrude-%EA%B8%B0%EB%8A%A5%EC%9D%84-%ED%99%9C%EC%9A%A9%ED%95%9C-hexa-mesh-%EC%83%9D%EC%84%B1-%EB%B0%A9%EB%B2%95 현재 생성하고 싶은 지오메트리의 일부입니다.…

hypermesh -3d mesh element mirror & revolve 가능 여부
안녕하세요. 원형 모터 stator의 3d mesh를 만들고 있습니다. 2d mesh를 이용한 후 map 혹은 extrude를 이용하는 방법도 있지만, solid split을 통해 케이크 모양으로 자른 후 revolve를 하고 싶습니다. 현재는 solid split-대상 solid에 2d mesh 후 3d mesh를 진행한 상태이며 이후 해당 element에 대해서 revolve 혹은 mirror 등의 기능을 수행하고 싶은데요. 질문 사항은 다음과 같습니다. revolve & mirror는 2d element에 대해서만 사용 가능한 것인가요? 일단 3d mesh…

hypermesh- component의 mesh간의 겹치는 부분 substract 가능 여부 & contact 조건
안녕하세요. hypermesh를 이용하여 작업중에 있습니다. 2개의 component에 대해 각각 mesh를 만들고 tie 등과 같은 기능을 이용하여 붙이고 싶습니다. 다만 2개의 component의 mesh element가 겹치는 구간이 없어야하는데요, clean-up 과정에서 두 부분의 겹치는 곳을 확인하였습니다. 이미 mesh작업을 한 상태에서 element끼리 substract가 가능한지 궁금합니다. solid상태에서는 3d boolean 기능을 이용하여 제거할 수 있는 것을 확인하였는데, element끼리도 가능한지 궁금합니다. 하나 더 궁금한 점이 있습니다. 두…

Flux & Simulink co-simulation - variation of geometric parameters
Hello, does somebpdy know if it is possible to change parameters used in the geometric definition of a machine (e.g. the airgap length or the slot width) in Flux when using the co-simulation in MATLAB/Simulink? It is pretty easy to do in a solving scenario when just working in Flux. However I wanna use the solution data in…

Mass-averaged total pressure
Dear all, I am currently working on a CFD simulation in SimLab and need to extract the mass-averaged total pressure at both the inlet and outlet of a pump. So far, I haven't been able to find a specific function or workflow in SimLab that allows me to compute or extract this quantity directly. As I’m still relatively new…

Multiple sine sweeps on random fatigue?
Hello, I have been able to run a sine sweep on random fatigue analysis. This includes creating a FATEVNT where a random load case is combined with a frequency response subcase. Now I have created an additional frequency response subcase, where I define a new sinusoidal sweeping load. I have then modified my FATEVNT card by…
