I want to do a TIG welding simulation using moving heat flux 
taking thermal boundary conditions as convection and radiation.

I am encountering an error as 

*** ERROR ***                           CP =      92.094   TIME= 00:45:36
 Subscript range error.  Parameter PT_LEN1 is dimensioned as 53 x 1,    
 but location -1 x 1 is being requested                                 
                                                                        

 *** ERROR ***                           CP =      92.094   TIME= 00:45:36
 No data exists for dimensioned parameter PT_LEN1 with subscripts -1 x  
 1.                                                                     

 *** ERROR ***                           CP =      92.094   TIME= 00:45:36
 The above error occurred processing field= DIST1-PT_LEN1(LOC31,1)      
  Line= *SET,RT,                                                        
 ((DIST%INDEX(INC2,1)%-PT_LEN%INDEX(INC2,1)%(LOC3%INDEX(INC2,1)%,1))/(PT
 _LEN%INDEX(INC2,1)%(LOC2%INDEX(INC2,1)%,1)-PT_LEN%INDEX(INC2,1)%(LOC3%I
 INDEX(INC2,1)%,1).

PLease help me

I noticed that the model works only if the time of moving heat source is 20 sec at 8 mm/s velocity but fails for 40 sec.

The radius of cylinder is 50.8mm which gives circumference to be 319.18 mm and dividing by 8 mm/s to get time of 40 sec. 
But it fails at 40 seconds 
Please help
