Spring connection for suspension arm assembly

Altair Forum User

Hi,

When i tried to perform quasi-static analysis of a front suspension with a flex body within spring connection between meshed parts, i have the problem as shown below:

'Static analysis terminated because absolute Max_delta_q_tol is satisfied.
ERROR: GTCMAT Initial Static Analysis failed!
 
ERRMES:USER [1]
Error computing Compliance Matrix for wheel center markers.
 
** EXECUTION STOPS DUE TO ENDFLG IN USER SUB **
WARNING: Statics analysis failed at time = 9.500E-01
----------------------------------------------------------------------------
WARNING: Statics analysis failed at time = 9.500E-01'.

And the h3d static ride analysis of the supension isn't available. i think that the problem comes from spring connections between meshed parts because i already have done this case with rigid connections.

i'm really waiting for your reply.
