Questions about crack growth code using extended finite method uel (Abaqus uel xfem code)

Submitted by Honggang Jia on
Respected all students and teachers,
  I am rencently study the xfem code (downloaded from  http://www.pudn.com/downloads247/sourcecode/math/detail1147440.html,
 you can input account number:Z770428 and password :770428 ,then download UEL_XFEM code for crack growth .)   but  I encounterd some questions , in the following is some code in UEL_XFEM code  of page 41 ,

ElemGGe       Matriz de caracterizaci≤n del elemento

c          Xe(8)      Coordenadas X de los nodos del elemento

c          Ye(8)      Coordenadas Y de los nodos del elemento

c          XG         Coordenada X del extremo de Grieta

c          YG         Coordenada Y del extremo de Grieta    

 

c      Outputs:

c          NumSub     N·mero de subelementos generados

c          SubXe(10,4)   Coordenadas X de los puntos de los subelementos        

c          SubYe(10,4)   Coordenadas X de los puntos de los subelementos

c-----[--.----+----.----+----.-----------------------------------------]

    implicit none

   

c     include  'eldata.h'

c  include  'iofile.h'

 

      integer dfich,dfich2  

      common /debugfich/ dfich,dfich2

 

 integer NumSub,n1,n2,l1,l2,lado,lado2,nl,i,tipo,lad,lad2,lads

    integer n,nel

    real*8  ElemGGe(8),XG,YG,xm,ym,x1,y1,x2,y2,xl,yl,xl2,yl2,xls,yls,

     &     Xe(8),Ye(8),SubXe(10,4),SubYe(10,4),tol

    logical comp

 

where , what is the meaning of ElemGGe(1),ElemGGe(2)....ElemGGe(10),what is the meaning of these variables n1,n2,l1,l2,lado,lado2,nl,i,tipo,lad,lad2,lads

    integer n,nel

thank you very much ,here I upload a pdf file named An Abaqus implementation of the extended

finite element method related this xfem .

 

 you must first download UEL_XFEM from http://www.pudn.com/downloads247/sourcecode/math/detail1147440.html,

 then you can read page 40-42

 

 

 I will be thankful if you can explain these variables ,you can upload a list to account for the meaning of ElemGGe(i).

 

Tkank you very much

 

 

 

Dear  Honggang Jia

I am working on a problem on fracture in composite and trying to implement ABAQUS 3D XFEM UEL code along with my subroutine.I tried to download the UEL_XFEM from the link mentioned but got some error messgae for the pasword.Can you send me the code at my email id pateldkp [at] uw.edu ?
