Adams/Car 2005 and 2018
(OP)
hello
I'm using an MSC model called mini-Baja that has been built in Adams/Car 2005 and anlysing it in Adams 2018 . Mind you , the files are ready on MSC Adams official site .
problem is that I can't get the exact results from Adams/car 2018 Postprocessing …( Minute differences ) the parameters I want are vertical chassis acceleration and chassis longitudinal velocity
no matter what I did from changing units to changing solver integrators ( to the best of my knowledge ) was nigh on futile ...
can you explain how this happens ? is it a matter of changing Solvers Integrators because I have tried almost all of them ? was there something in Msc /Adams car back in 2005 that is changed in 2018 ? if so what can i do to get the exact results ?
my results are very similar to the results of the model in 2005 but with minute differences ? what is the reason of those minute differences ?????
FYI : i'm running the model in File Driven Events and the Baja vehicle model has post-made files for that ...
thank you very much

RE: Adams/Car 2005 and 2018
When each new version came out we used to run standard models through them and check that the results were reasonably similar. They were often different. That discipline seems to have faded away, but at least it means we can run the later versions (2013 in my case).

RE: Adams/Car 2005 and 2018
mind you , it is "Slightly" different ... but still ...
RE: Adams/Car 2005 and 2018
I don't know if it runs, i don't have time to mess about with it.

RE: Adams/Car 2005 and 2018
thanks anyway
so i have uploaded an image of my analysis(exact same model and tets File Driven 2018 ) and the result of the model itself in 2005
would you tell me if the diferences are normal ?
as you said the differences often happen so these minute diferences that i have circled with blue would be normal right ?
sorry to consume your time ...
also i detected that with the units being different in each model but resulting the same peaks in the gragh , the original model units might be wrong ( by the owner or builder of the model )

RE: Adams/Car 2005 and 2018
The model you are working with will be translated/exported to the form that the solver can understand. All it takes is for the MSC team to make some change in the the export scheme and you'll get a different result. As your GUI starts working with ever more abstract concepts, the direct mapping from GUI to solver disappears. You might find details in the release notes, if a subsystem's export method has been improved.
