我在ansys里建立了幾個(gè)變截面梁?jiǎn)卧哪Ｐ停瑔蝹€(gè)模型都可以進(jìn)行分析計(jì)算，并都未出現(xiàn)錯(cuò)誤。但是當(dāng)我把這幾個(gè)模型合并起來(lái)時(shí)，卻總是出現(xiàn)類似以下的錯(cuò)誤，而且不能計(jì)算：

Element 55 integration 1 point is located outside of end stations.     
 Please verify section input 1.000000805. 

我合并模型所用的命令為：                                                                       
FINISH                                                                   
/CLEAR                                                                   
/PREP7                                                                   
/INPUT,'A1,'TXT','F:\model\',, 0    
CDWRITE,ALL,'A1,'cdb',,'A1,'iges'                    
                                                                         
FINISH                                                                   
/CLEAR                                                                   
/PREP7                                                                   
/INPUT,'A2,'TXT','F:\model\',, 0    
CDWRITE,ALL,'A2,'cdb',,'A2,'iges'                    
                                                                         
!!合并模型!!!                                       
FINISH                                              
/CLEAR                                              
/PREP7                                              

CDREAD,ALL,'A1,'cdb',,'A1','iges'
CDREAD,ALL,'A2','cdb',,'A2','iges'

/SHRINK,0   
/ESHAPE,1.0 

這個(gè)命令流我之前用來(lái)合并過(guò)別的幾個(gè)模型（這幾個(gè)模型沒有變截面），并沒有出現(xiàn)錯(cuò)誤。請(qǐng)問(wèn)各位這是怎么回事，是不是這個(gè)合并模型的命令流不適用于變截面梁？若是這樣，各位有什么別的方法合并ansys模型？
