MotionSolve 2025.1: Vehicle ignores vertical profile (Z-axis) of 3D Spline Road in Roadcourse Event
Hi Altair Community, I'm currently running a vehicle dynamics simulation in Altair MotionView / MotionSolve 2025.1 using a Roadcourse Event. I am encountering an issue where the vehicle model does not track the vertical elevation (Z-axis) of the road profile, remaining completely flat throughout the simulation. Here is my…

Reading coupled geometry pose in an EDEM Particle Body Force UDL (MotionSolve co-sim)
Description: 현재 EDEM–MotionSolve Co-simulation을 통해 CFD Field Data를 EDEM에 적용하는 시뮬레이션을 진행하고 있습니다. 형상(Geometry)의 Motion에 따라 Field Data의 적용 위치도 함께 갱신되도록 구현하고자 합니다. 즉, 형상이 이동·회전할 때 그 움직임을 Field Data가 따라가게 하여, Particle Body Force UDL에서 필드 기반 힘을 형상 기준으로 조회하려고 합니다. 해당 형상은 시뮬레이션 중 이동하며 pitch 각도가 변합니다. 이를 위해 EDEM API의 Geometry 관련…

Regarding the damping settings in Inspire/Motionview
I currently have an object consisting of three bodies that form a rigid group on top, with a plate below connected to the ground. The three upper bodies slide on this plate that is connected to the ground. I will apply a horizontal leftward force to the upper rigid group. I have now set a damping for the sliding joint in…

How to use Joint functions in Inspire Motion?
The Joint functions in Inspire are different from MotionView's. What's the right way to use them? this is motionsolve: I verified in MotionSolve that this fixed flexible joint does carry force in the X direction. But when I use the Joint function to measure or output it, the force reads zero.…

How to define a multi-stage (ramp-up then constant) velocity profile for a Constant-Radius Cornering
Hi everyone, I am currently running a vehicle dynamics simulation in Altair MotionView 2025.1 . I am setting up a Constant-Radius Cornering Event. By default, the event only provides Initial Velocity and Final Velocity inputs, which creates a continuous linear acceleration (ramp up) throughout the entire simulation time.…

Different Steering Angle Limits for Left and Right Steering
Hi everyone, I would like to ask whether it is possible to define different maximum steering angles for left and right steering. When I run a K&C event, I can only find one parameter for the maximum steering angle, which seems to be applied symmetrically in both directions. Is there any way to specify different limits for…

Full Vehicle Model Flies Upward and Solver Fails with Integrator Error After Hardpoint Modification
Hi everyone, I'm working with a standard Full Vehicle Driver template in MotionView and modified the hardpoints to match my target vehicle specifications. After updating the hardpoints, I ran a Kinematics and Compliance (K&C) simulation, and all the suspension links moved and articulated properly without any issues.…

A few questions about the installation of the md-plugin-v2026-x for Motionview.
I've just installed md-plugin-v2026-x. The extraction path is shown in Figure 1, and I've set up the system variables as shown in Figure 2. However, the MD_Tools button in Hypermesh doesn't respond when clicked, and in Motionview it throws an error (see Figure 3). Am I missing some steps? Any feedback would be greatly…

When can EDEM support OSFLEX body coupling in Motionview?
Because I am currently working on a project that requires consideration of the nonlinearity of the material, which needs to come into contact with particles. However, after my research, Motionview has launched an OSFLEX flexible body function, which is currently a testing function and cannot be coupled to EDEM. Therefore,…

Motionsolve Case 7022: Several Questions
I am using the 2026 version of Motionview and now I want to do bidirectional coupling between MS and Optistruct. I saw that the 7022 case is about this, but when reproducing the 7022 case, I checked the flex body and did not see the functional source and Input Optistruct in the tutorial. Do I need to set anything for this?…

Can EDEM couple with the explicit algorithm of a structural solver other than OptiStruct?
I have a polyurethane screen panel. Using MotionView, I’m not able to reproduce its motion, and the panel also needs to interact with bulk material. Therefore, I am considering using OptiStruct as the solver. However, I feel that OptiStruct does not provide as many explicit analysis control options as Radioss. So I would…
