Hello, I would like to script the creation and assignment of a reference point to a geometry set in abaqus. In the .jnl file the code is:
mdb.models['Unsieved_addCZE'].parts['PART-1'].ReferencePoint(point=(50.0, 10.0,
0.0))
mdb.models['Unsieved_addCZE'].parts['PART-1'].Set(name='RP', referencePoints=(
None, ))
#* TypeError: referencePoints[0]; found None, expecting tuple
mdb.models['Unsieved_addCZE'].parts['PART-1'].features['RP'].setValues(xValue=
150.0)
mdb.models['Unsieved_addCZE'].parts['PART-1'].regenerate()
mdb.models['Unsieved_addCZE'].parts['PART-1'].regenerate()
mdb.models['Unsieved_addCZE'].parts['PART-1'].Set(name='Set-244',
referencePoints=(
mdb.models['Unsieved_addCZE'].parts['PART-1'].referencePoints[725], ))
I would like to automate this process so I wrote a . py script with the following:
myRP= mdb.models[name].parts['PART-1'].ReferencePoint(point=(150.0, 10.0, 0.0))
r = mdb.models[name].parts['PART-1'].referencePoints
myRP_Position = r.findAt((150.0, 10.0, 0.0),)
refPoints1=(myRP_Position, )
mdb.models[name].parts['PART-1'].Set(referencePoints=refPoints1, name='RP')
Why does my code not assign the created reference point to the set? I end up having to do it manually and it is a bit annoying.
within provided code, it seems that you are creating a reference point called `myRP` at coordinates (150.0, 10.0, 0.0) in the part named 'PART-1'. Then, you attempt to find the reference point at the same coordinates using `r.findAt((150.0, 10.0, 0.0),)` and store it in `myRP_Position`. Finally, you create a set named 'RP' with the reference point `myRP_Position`.
The issue in your code lies in the creation of the set. Instead of passing the reference point `myRP_Position` directly to `Set(referencePoints=refPoints1, name='RP')`, you need to pass the actual reference point object `myRP`. Here's the corrected code:
```python
myRP = mdb.models[name].parts['PART-1'].ReferencePoint(point=(150.0, 10.0, 0.0))
refPoints1 = (myRP,)
mdb.models[name].parts['PART-1'].Set(referencePoints=refPoints1, name='RP')
```
By using `refPoints1 = (myRP,)`, you create a tuple with the reference point object `myRP` as its only element. Then, this tuple is passed to `Set(referencePoints=refPoints1, name='RP')` to create the set named 'RP' with the reference point `myRP`.
Make sure to verify that the part named 'PART-1' exists in the model named `name` and that you have the necessary permissions and access to create reference points and sets in that part.
Hope it helps
Hi Mohammad.
Thanks for your reply. I tried the code you recommended but, I still get this error TypeError: referencePoints[0]; found Feature, expecting tuple. I have checked that PART-1 exists and I have the right permissions. Would you have any other suggestions?
Thanks.
