Wheel Loader Simulation using MotionSolve and Activate
Overview This is a co-simulation example of a wheel loader model using MotionView / MotionSolve along with Activate. The simulation: * Models the dynamic effect on the wheel loader during operation * Connects a hydraulics model in Activate with mechanical model in MotionSolve * Predicts the stress in Boom, Connecting Rod…

Convert RADIOSS model to LSDYNA
Hi, Is it possible to convert RADIOSS model to LSDYNA model? If so, can we convert everything? Contacts, boundary conditions, materials, properties, etc... I have seen an answer from 7 years ago using HyperCrash, but I don´t know if it is still a valid solution.…

Exclude single ply from composite optimization
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…

Is there any tcl script for property or component renumbering based on the same component with different thickness.
I have one component with different thickness. For example: 1.5024XXX-1XX, 0.96 thk 2.5024XXX-1XX, 0.58 thk 2.5024XXX-1XX, 0.36 thk So for the above example i want to give the numbering sequence one after another instead of the random number.

Reflection of pressure waves in piping systems with HW
Hello, I have a questions about a possible study: is it possibile with HW CFD to evaluate the reflection of pressure waves? For examples I inject a periodic pressure forcing on one side (is it possible?) and I want to see how the pressure varies at different points in time. For an open pipes (one inlet and one outlet) and…

Modal Frequency Response Analysis 관련 질문입니다.
안녕하세요, 한화시스템 위성시스템 5팀 신현철입니다. Hypermesh/Optistruct를 이용하여 진동해석을 하고있는데요 해당 해석을 하기 위해 Load Step의 Analysis type 중 'Freq. resp [modal]'을 이용하고 있습니다. 여기서 궁금한 점이, 요소수 가 많은 시스템 레벨의 FE Model은 대부분의 해석 시간이 EIGRL혹은 EIGRA 카드를 이용한 고유진동수 해석에서 소요됩니다. 혹시, Normal modes 해석을 별도로 수행한 후, 결과 데이터를 이용하여 주파수 응답해석 및 랜덤진동해석 에 활용할 수 있는 방법론이 있을까요?…

Unexpected Decrease in Total Contact Force and Discrepancies in Flexural Strength Predictions in Three-point Bending Simulation
Hello, I am conducting a three-point bending simulation of a composite material using Radioss. However, I am encountering an issue where the total contact force consistently begins to decrease at a fixed time, regardless of the failure criteria employed. While the predicted flexural modulus aligns with experimental…

Sanity check: conservation of angular momentum problem (sprinkler rotation)
Hi, I'm trying to perform a co-simulation (acusolve-motionsolve) to solve a sprinkler rotation problem similar to this, I've finished the set-up lunched the computation, with no errors, while waiting for the solution to converge, I want to make sure that the problem is properly set up since I do not have a strong…

What does this mean! Hourglass Possible On Shells?
hi, Recently I have created a Radioss crash model, I exported the 0.rad model and import it into HyperCrash to do a model check, what I find really really confusing is that it throws a warning saying that there are shells with possible hourglass? But what does it even mean? I have not been able to find information about…

Hi, can anyone help to please identify the orientation i.e. X, Y, Z, RX, RY, RZ directions of the compliant universal joint in the images attached? - (joint is as per front lower control arm unv joint from multilink template)
Image1 shows the joint definition and coordinate orientation and how it is oriented via two axes. I've sketched three orthogonal directions and the joint is selected in the image - 1) one along the direction of the control arm to the knuckle hard point --> (is this X direction?) 2) one along the bushing axial direction…
