Accelerations with Adams_postprocessor/object/body/CM_acceleration
&
Accelerations with Adams_postprocessor/Result Sets/part_xform/ACCZ
are different for dynamic simulation with contact forces present in the model.
Can anyone help…
Is there a list of Adams enumerations somewhere? I am writing a python script and when a variable requires an 'enum' to be specified, I do not know where to look. In this case, I need the enumeration to specify coulomb_friction.
I noticed that when using Adams View 2019.2 it was crashing a lot when solving a lot of contacts, though when I switched to 2021.3 it stopped crashing, does 2012.3 have better capability with contacts/large forces?
Hi all,
Running my ADAMS simulation, I get the following error.

ERROR: Time 0.000000E+00:
Acceleration computation failed to converge after 25 iterations.

Hello everyone.
I have an issue about conducting DOE with use of Insight and Vibration, where eigenfrequencies are used as response factors.

Hello,
I wanted a clarification on this - do adams measures display the value of the measured object at the current timestep or the value of the timestep prior to the current one?
Thanks,

Hello,
I am trying to estimate the torqie required to drive a lead screw. To do this, so far I 've been using a motion instead of the torque and then viewing the required torque to produce said motino throught the ppt. This doesn't seem to…
Hello,
I have an Adams model which calls two different user subroutines. How can I ensure that one of them is evaluated before the other? In my proble the order of evaluation is of great significance.
Thanks.

The model has been modified by changing the connectivity of some Markers located on Flexible bodies having more than 40 active modes. See environment variable MSC_ADAMS_SOLVER_FLEXBODY_BOOST_THRESHOLD…
Hello,
I am trying to extract information about the contact incidents in Adams, in order to exact the times at wich more than 1 gear tooth pair of an involute gear model come into contact. I understand that after the simulation, I can look…
Hello,
Is it possible to use a measure as input to the user input values of a subroutine? I want to use the previous values of a contact force in order to change the force's value in the current step i.e., I want to create a measure of a contact…
Hello,
I built a .dll file containing a subroutine I use in Adams on a Windows machine. I am now trying to run the same model on a Linux machine and the .dll file doesn't work (due to the thact that Linux doesn't use .dll's I believe).

Hello,
I used the Cnfsub to print out the contact normal force and noticed that the force estimated by the impact function doesn't directly translate to the force components inside Adams. How does Adams calculate the contact force components…
Hello,
In the Adams online help for Cnfsub, it is stated that the ni, nj variables are the direction vector arrays for the normal contact force. However when viewing their contents, they seem to contain only a single value. How is the contact…
I would like to model frequency and amplitude dependent behavior in Adams View.
In Adams Car Ride there is a Component based on a GFROCE that computes a force which is the sum of static spline force, TFSISO force, Bouc-Wen hysteresis force, preload…
Hello,
I am trying to understand how the damping ratio is introduced to a flexible body in Adams. I understand that CRATIO acts as a percentage of the body's damping ratio but what I don't know is wether I should create a TABDMP card in the…
Hello,
I am trying to build a subroutine to swap out the Hertz contact force model with one of the more complex ones (e.g. Flores et. all). What I don't understand is how the c_impact function returns three force components when the gap and…
I want to obtain the each node displacement of Flex Body after simulation, which contains not only the deformation due to part compliance, but also the "rigid motion". That means: coordinate of each node.

Hello,
I s there a way to import a custom road model in Adams/View to simulate a run different than the available Adams road files. The available road templates are not suited for my task.
Thanks,

I have an ADAMS bearing model where the motion of the cage or inner race is in the magnitude order of microns and I need to scale the motion of the parts while animating so others can see it. I've heard that "visualization plus" does what I need.
Hi folks,
I was wondering how I can exaggerate the motion of the component in my Adams model. I have a bearing Adams model where the motion of the cage or inner race is in the order of micron and I need to exaggerate the motion of the parts while…
When I change the working directory of ADAMS, I always use File---Select Directory, and then use the dialog to select a new dir. I can't find a directly command about this , can anyone give me some advices?
