DEFINE A REGION

[chourouk]

Hello
How can I define a region through edges such as edge[0],edge[3],edge[4].....
On the other hand the number of these edges is variable according to the case
for example i make this :
region = p.SetFromElementLabels(elementLabels=edges11, name='Wire_cubic_cell1')
p = mdb.models['Model-1'].parts['Part-1']
p.SectionAssignment(region=region, sectionName='cylindrical_section1', offset=0.0,
offsetType=MIDDLE_SURFACE, offsetField='',
thicknessAssignment=FROM_SECTION)
such as edges11 contain the index of edges,edges11=(0,3,4,7,8,....)
but in the affection of section i have error "region, found none,expecting region

thanks

Do you want to create a set with elements or with edges? Clarify what kind of entity you want to use and don't mix it randomly.

with edges!

Do you want to use all edges of your part? Then you could use a slicing, that is larger than needed.

p = mdb.models['Model-1'].parts['Part-1']
e = p.edges
edges = e[0:100]
p.Set(edges=edges, name='Set-1')

I do not want to use all the edges but I want to use some edges already chosen

Then do it with a loop and combine the single slices.

p = mdb.models['Model-1'].parts['Part-1']

ids = [1, 3, 4, 7]

for i,x in enumerate(ids):
	if i==0:
		eregion = p.edges[x:x+1]
	else:
		eregion = eregion + p.edges[x:x+1]

p.Set(edges=eregion, name='Set-1')
