    Objective-based driver

    Hello, I want to test a vehicle on a specific road profile by requsting an objective (e.g. minimize travel time). Does the Adams SmartDriver support this feature and, if not, are there any alternatives? Thanks in advance, Josef

    Parrallel tasks from createjob

    Hello, When using createjob/createtask, do the outputs of the job come in the order they were requested, or in the order the tasks finished? e.g.: Supposing I submit 8 tasks for a job, expecting a scalar output, denoted as fOUT from each. What a I want to receive from the job is an 1by8...

    adams_car_flexbody

    Hello, I am building a cart in Adams Car and I wanted to ask if there are any specific steps in importing a flexible body. So far I have modelled my subsysetms and added a part for the chassis which I am later going to make flexible by importing an MNF file. Are there any specific steps that I...

    Custom contact force models

    Hello, I need to define a custom contact force model in Adams/View but I cannot find the order of actions I need to perform. As I understand it so far, I need to select: "User Defined" "User function" -> Define the values that need to be exported/imported from and to Adams "Routine" ->...

    User defined functions and subroutines

    Hello, I wanted to try using a UD subroutine/function to define the contact forces in Adams, but so far I haven't been able to find any straightforward documentation. Is it possible do define function that outputs Adams values such as displacements and receive forces? If so, are there any code...

    Flexbody markers

    Hello, When placing markers on flexible bodies, if coordinates are specified instead of a node ID, will the marker be properly attatched to the flex body, so that requests can be estimated properly. e.g. If I wanted to measre the acceleration at a point of a flex body with respect to the...

    Large nastran jobs

    Hello, I am trying to run a large nastran job (16272552 DOFs). My computer has 32 Gb RAM and 900 Gb of free HDD space. When excecuting, the scratch file created is quite large (143 Gb) and for some reason, the solution just freezes without warnings. I have found documentation about keywords of...

    Adams/Car custom geometry import

    Hi, I wanted to ask whether or not there is a point in importing custom geometry in Adams/Car. I understand that the graphics are altered in such manner, but does it change the calculation at all? So far, the only way I 've managed to import geometry was by attatcing it to an already existing...

    Time Synchronus Average - tsa - MATLAB

    Hello, I am trying to understand how the tsa function works in matlab in order to use it for gear drivetrain signal analysis. I get that for: y = tsa(x,fs,tp) - x is my dataset - fs is the sampling frequency What I dont understand is how to calculate tp. So far, they way I used the...

    ADAMS Request output steps

    Hello, I 've tried a lot of different formulations and settings when trying to output a request file from and ADAMS model, but none of them managed to keep a completely steady output step. What I mean is that even thought I request an output about every 9e-5 seconds (10240 Hz sampling...

    ADAMS/SOLVER

    Hello, This is kind of a general question, but I've had a lot of trouble finding an answer. Are there any tips/rules of thumb to use when modeling with MSC ADAMS that would result in a more numerically stable solution, or that would allow the solver to converge faster? So far, in every model...

    Contact stiffness MSC ADAMS

    Hello, I am having a bit of trouble understanding how the adams contact works between gears. Does the software account for the contact of more than 1 pair of teeth simultaneously? I know that the machinery module, for the spur gears, has a detailed selection that does account for up to three...

    RAM size Adams Solver

    Hello, Is there a way to increase the RAM available to my Adams Solver? My computer has a 64 GB RAM memory and adams uses a maximum of 10 GB. Is there a way to take advantage of the rest (or part of it). So far I have only come across the MEMSIZE command, but as I understand it, it is meant to...

    Motion function builder msc adams

    Hi, Is there a way to import numeric data (deg/sec vector in my case) as motion in msc Adams? I have previously calculated and extracted the data for the exact run time i mean to use. Thanks in advance.

    MSC ADAMS adm file

    Good evening, I am new to this, so please forgive any irregularities in the way i post this. I have exported an .adm file from an MSC ADAMS .bin model, but for some reason the bearings from the .bin model don't get passed on to the .adm file as bearings, but rather as simple...
