Adams car problem

Hello guys, im a student in a formula student team, since last year i had been having the same problem with adams car i had no found a solution to this, maybe someone can help me. this is the problem

does the tire file exist ? can you navigate to it ? then why can't the Adams s/ware find it ? (ask Adams help desk or someone else ... teacher, someone doing the same problem, ...)

the file exist, i can navigate, the problem is that my university haven't a direct teacher, we hire a teacher from hexagon that show us how it works and he doesn't answer any mail i already send him, if yo can help me or give a posible solution i will apreciate

 

[rb1957]

well, that's a pain !

others in the class have the same problem ?

can you copy the file to a local folder, and work from there ?

maybe Adams helpdesk could help, but maybe you don't have an official license ?

 

[Zapsro]

well being the only guy in my entire formula student team to manage adams its a problem, i had already try that with the files gives by the program but still dosean't work i will try helpdesk i let you know

The problem is, as ADAMS has told you in unusually informative error message, that ADAMS can't see you tir file.

So is this database registered in the database manager? mdids://fsae_2018/ As you can see it isn't a filesystem type folder, it is a nickname.

Have you done the tutorial?

BTW in all honesty ADAMS is overkill for an FSAE team, you are much better off writing your own bicycle models etc or repurposing Bill Cobb's scripts, or using Dynatune, and using CAD for the kinematics. You will spend 6 months of your valuable time at uni learning to become a frankly wet behind the ears ADAMS guy/gal and with no correlation data your model is a hallucination.

hi greg
first of all yes it his in the manager database the error started with the 2024 version in the 2023.4 version it work i has asked in diferent forums and any had give me a solution

i know that adams is a overkill trust me you are not the first guy to tell me this, i had already comment to my team lead and the answer is to continue, im already burn with adams but im trying my best. i sure to you that i being using adams for a hole year and its frustanting that adams gave me more problems that solution

 

[GregLocock]

Sadly I don't have ADAMS any more so i can't really help. Have you looked on the hexagon forums to see if any other users have the same problem? Why can't you use 2023.4? I'd never change version during a project unless it was to fix a specific issue.

You could try rebuilding the model from scratch, that is open a new assembly , and select each subassembly manually. Then save it as a new model.

i can't use 2023.4 version because my university upgrade the whole systeme in all the computer is very difficult to talk with one of the technician (they almost don't exist) i had search in reddit and other forums and any have gave me the solution its almost like a new problem idk, i had already do your idea but didn't work. i already send some email to hexagon people and i haven't recive a answer.

Hi,

Since you are a Hexagon-MSC customer you have access to the support service. You should find further information in the initial email they sent you.
In any case, I will be happy to discuss this topic with you. It's either a typo, missing file or faulty cdb.

thanks,

I disagree it's an overkill. Knowing ADAMS makes your CV much more attractive than any other reduce order model (ROM) software techniques. You will be able to use any ROM software with ease afterwards.

Hi,
Do you know that by participating in FSAE your team gets free licenses? this means you won't need to rely on the University. Just contact Hexagon-MSC

Overkill

You have 4 years at university. It takes us 6 months to get a full time employee up to a useful state with ADAMS, and we peer review some engineer's models for a lot longer than that. Spending 10% of your mental energy at uni on a little used software package seems like a high risk approach. I'd far rather recruit a graduate with self developed vehicle dynamics scripts or spreadsheets and a good understanding of RCVD and tires than someone who has managed eventually to produce an uncorrelated simplified ADAMS model using somebody else's templates that actually runs. Not that we're recruiting. A typical path is graduate->work in various departments on rotation-> work in vehicle dynamics for 2 years -> start picking up ADAMS.

Hi Greg,
Thanks for your feedback and your experience. However not every business thinks the same way: Many of them want graduates with experience in MBS tools, some of these spend the time/effort/money providing training some of them don't and just tell the employee to work it out.
I must admit that I was thrown at it and took me longer than 6 months to pick it up fully. I believe a mix of what you and I are proposing could work if the student is keen on doing the extra effort required.

I tried to open my files in version 2024 and didnt encounter like that. 99% that the root of the problem is in tire-file. Or its interaction with road-file (maybe 3d-contact or something like that). Check again that everything is ok. And if possible, reset tire-file configuration here on the forum.
