powertrain template question

[bj7777]

hi everyone

when i turn the _powertrain_advanced which is in the acar_concept, into a subsystem, i can't change gear and it gives an error.
The light beside the gear number option in the test window is off and cannot determine the gear number.

would you please help me and tell me why the default _powertrain_advanced template has this problem when directly turned into a subsystem and why does the default powertrain subsystems do not have this problem?

thank you very much

this is what happens when i want to perform a test when i build the subsystem directly from the _powertrain_advanced template.

this is the error that i get:

Looks to me as though you are failing statics. Try a more straightforward event. I assume you have set your gears up somewhere?

[bj7777]

yes i have set up the gears in the powertrain template. I used the Adams default powertrain...
honestly i can't go more straight forward than this. i use default manual gears with the exact same values and i change nothing in the template except the hardpoints. The hardpoints are reasonable mind you. This is the Error that i get:

and also the same thing happens for the test window (the gear light thing being off)

 

[bj7777]

Could the problem be somewhere in here that i found in Adams/Car Help:

If yes, how can i fix it?

thanks for replying GregLockock

 

[GregLocock]

Unfortunately my dealings with /Car have been tedious and unpleasant. I am now happily back in the land of Chassis. Can you post a screenshot of your vehicle subassembly list, I'll build the same thing and try it on Monday. You might have more luck with the FSAE forums in general, they tend to use Car, or of course MSC itself. This really is a case of the blind leading the blind I'm afraid.

Thank you very much anyway.

I will try other forums as well
