标题: 请教各位柔性体仿真问题 [打印本页] 作者: yuzhenyan 时间: 2005-8-8 17:36 标题: 请教各位柔性体仿真问题 我在对一个构件全部为柔性体的两自由度机构仿真时，其中一个驱动为：30d*time ,另一个为40d*time时可以仿真，但是当把第一个驱动改为3000d*time,第二个改为：3600d*time的时候，出现错误提示，无法仿真下去。求解器选用ABAM,Maxit=50.下面是错误提示：WARNING: The value 50 was specified for the BDFPAR/ CRMAXIT argument. Since the corrector algorithm in the BDF methods should converge very rapidly,such a high number of iterations should not be necessary and may cause an excessive consumption of cpu time.
WARNING: After 10 corrections to the state vector, the iterative
algorithm has not reconciled the displacement coordinates with the constraint equations to within the specified tolerance of 2.50E-04 .
FAULT: DDEABM: AN APPARENT INFINITE LOOP HAS BEEN DETECTED. YOU HAVE MADE REPEATED CALLS AT T = 6.86966E-02 AND INTEGRATION HAS NOT ADVANCED.CHECK THE WAY YOU HAVE SET PARAMETERS FOR THE CALL TO THE CODE,
PARTICULARLY INFO(1). .
ERROR: Program Fault encountered in Solver.
到底在哪里出了错误。请各位高人指点， 作者: tangbaiwen 时间: 2006-6-26 00:15
给的驱动数值太大，求解器当然无法计算！
