整车仿真问题

wzc71

为什么我的2005 做不了整车仿真分析阿，看论坛上说换轮胎，可是换了之后还是有问题啊？如下
---- ERROR ----
   Attempt = 1. No convergence after 25 iterations. Best iteration = 20.
   Trying next attempt with a different set of statics parameters...
  

STATIC:NOCINFO
   For the last attempted iteration the equation with the largest error
   was GSE hjik_sin.TR_Front_Tires_til_wheel_tire_gse  Error = 1.42505E+06
  
   The variable receiving the largest increment
   was GSE hjik_sin.TR_Front_Tires_tir_wheel_tire_gse  Delta = 2.88687E+11

STANAL:STAT_FAIL

---- ERROR ----

请高人指点。
再有 一个问题是，SOLIDWORKS建的悬架模型导入car模块中用加 束角和外倾角吗？以及约束什么的？
