During full vehicle simulation I got the message "NearestPoint". even if i can finish my simulation. Is there any possible solution to cover out it? or what the most posibility casused the case.
Dear community,
I have a multibody dynamics model of human body in Adams. Currently the intervertebral discs (IVD) are modeled as bushings with stiffness and damping. I am trying to model IVDs with flexible bodies option in Adams. I was able to import…
Hi,
I am using following command to generate leafspring
call adams2021_2 -makeleaf "leaf.ltf"
I get following error. The ltf files which were running earlier, are also showing this error.
Please help…
Can we deactivate a motor during simulation? I'm running the simulation through an ACF file and would like to deactivate the motor once a sensor gets triggered.
Hello,
can someone help me with my problem in Adams View. I am simulating two finger robot gripper. I am simulating it on the cube. Now I want to parametrize that cube to be able to move it on x, y and z. i want also to be able to rotate cube.

I’m building a new model where I need to bolt two flex bodies together. Part of the goal of the model is to understand the changes in Bolt loads as the system is exercised. We are a “weld the heck out of stuff” kinda place…
Hello together,
does someone know the difference in the solving process from adams with the external to the internal solver?
Sometimes I have models where an error occurs during the simulation with the internal solver where the external…
I have a flexible shaft in my model by importing an MNF file. I have found the deflection of the shaft (simply supported) is dependent to the number of modes. Only a radial load is applied to the shaft center and I need to confirm the shaft center displacement…
We've developed a C++based DLL for an Adams model. The code includes Gse-deriv & Gse-output functions. It works perfectly fine with the dynamic solver "Sim/DYN" and the simulation results have been successfully validated; however, with Sim/STAT, it encounters…
I am trying to simplify some messy equations by using runtime functions. I have a function for projecting the velocity vector of a marker into the plane of a reference unit vector that I calculate and save at some previous point in the simulation.

I have drive and driven gears mounted on the drive and driven shafts respectively. Torque and speed are applied to the drive shaft. When my dynamic simulation starts, some random force is generated but when it reaches a steady state, the transmitted force…
Hey there,
does anyone know if there are keyboard shortcuts for hiding and showing selected objects in Adams View? I could not find anything in the online help. Also shortcuts for activate/deactivate would be nice.

I've created a leaf spring using "Leaf Spring Editor". However, I've been struggling to draw its Load/Deflection diagram. For that purpose, which parameters should I use in x-axis and y-axis in the postprocessor interface?
For instance, I've…
Hello,
I have two questions about using SYSARY in subroutines:
1) How can I tell the units at which SYSARY outputs the data (e.g. velocities)? I have set units in Adams as mm/deg but I think that my angular velocty components where…
I know the order about acar.bin ->acarBS.cmd ->acar.cmd ->acarAS.cmd
But I dont know what kind of command should be written in acarBS.cmd and what should be placed in acarAS.cmd
I'm opening an A/Car tire template (or the subsequent vehicle assembly) and getting the following error messages during the "converting" process. The template/assembly is from a few years ago and I believe was working fine. I think this is a new message…
I calculate a model with resolved wishbone (Multi Link) in Adams. I have also created a CAD model in which I calculate the steering axle for different wheel travels.
Unfortunately, I have a relatively large deviation from what Adams calculates.…
I have a large number of non-linear springs (force as function of displacement) in a large model. These spring forces, whether from a spline or simple functions, go to 0 force after a certain displacement is reached. What I want to ensure is that the…
Hello everyone,
I would like to open in GNS Animator 4 the result of a 4Post Testrig from Adams Car. Anyone knows if that is possible? I don't find any postprocessing output from Adams which is able to be opened in GNS Animator 4 as animation.
In a C++ version of a DLL code for an Adams model, I am trying to store some packages of property parameters as a linked list using the “Struct Node” concept, in such a way that each node to be devoted to one package of input parameter.
To do so…
I always got a .out file of request data in ADAMS 10.1 but now in ADAMS 2021 it seems like something has changed. I found Output (out) content in the Help documentation. I checked request data, exported to .adm and see the line

Hello,
I am trying to understand how Bearing AT works. In the manual, it says that the order of operations is:
1) Preprocessing mesh -> generates .bpf, .bof, .bif files (for ball bearings)
along with the .pch files from Nastran…
Hi everyone,
I would like to know how to properly define dual wheels in acar. There is no problem when I create single wheels(left and right) and simulate them. The wheels remain stationary on the ground with the reaction force equal to the…
