Regarding to selecting cell with Python script

[Adil Memet]

Hello, Dear Friends
I am new to this site and I found it useful discussion about problems we all are dealing with. I have a question about some advice about how to select cell with python script, in which, I created first "Step" then in correspondingly it has to select element from mesh element shown in the picture. basically, first "step" is created then in the interaction model or option, it has to select first cell for activation or deactivation , for the second "step ", it has to select cell number 2 for activation or deactivation and so on. my question is how to write to loop so that it can select one single cell element make interaction. Thank in advance.

Python script:

from part import *
from material import *
from section import *
from assembly import *
from step import *
from interaction import *
from load import *
from mesh import *
from optimization import *
from job import *
from sketch import *
from visualization import *
from connectorBehavior import *

Tol=0.000000001
Speed=0.01
##Pass1
for i in range(2,196) :
mdb.models['Job-1'].HeatTransferStep(deltmx=500,initialInc=0.05,maxInc=0.2,
maxNumInc=1000000,minInc=1e-11,name='Welding-'+str(i),previous='Welding-'+str(i-1))


##activation
for i in range(1,195):
mdb.models['Job-1'].ModelChange(activeInStep=True, createStepName='Welding-'+str(i),
includeStrain=False,name='Welding-'+str(i),region=Region(elements=mdb.models['Job-1'].rootAssembly.instances['Part-1-1'].elements.getByBoundingBox(
-Tol+Speed*(i-1),-(0.0075+Tol),-(0.005+Tol),Tol+Speed*i,0.0075+Tol,Tol)), regionType=ELEMENTS)

 

[FEA way]

Are you trying to simulate welding ? Did you know that there's a built-in functionality for that available in Abaqus ? It's meant primarily for additive manufacturing process simulations but it can handle welding too.

Thank you very much for your quick reply, actually, I want to simulate cutting process (material removal) with moving heat of predefined geometry, which is coming from house coded software as surface mesh element (stl data), yes, you are right, I want to conduct additive manufacturing process simulation for the case of material removal and I want to use model change method for my simulation. Thanks.

Best regards
