API on Python to modify the reference node rigid elements

API on Python to modify the reference node rigid elements

API on Python to modify the reference node rigid elements

I'm having some troubles when I try to modify the reference node of a rigid element
or create a new one.
I used the "Node" property of the element object, as depicted in the following code line, where 2 is just an example:

feElem.Node(0) = 2

Quoting pyFemap:
# The method Node is actually a property, but must be used as a method to correctly pass the arguments
def Node(self, nVectorIndex=defaultNamedNotOptArg):
return self._oleobj_.InvokeTypes(18002, LCID, 2, (3, 0), ((3, 1),),nVectorIndex

Since one must use Node as a method, it is not possible to assign a value to it. This way, I am not being able neither to modify nor create a RBE.

Does anyone know a way around it?

RE: API on Python to modify the reference node rigid elements

" feElem.SetNode(0,2) " should do the trick.

This is a common issue writing FEMAP API through Python, since Python makes a harder distinction between how properties and methods pass arguments. Typically any time you want to write a value to a property, there is a corresponding method in the PyFemap library, of the type " [property] / Set[property] ". Take note that these "Set[property]" methods are not methods within the FEMAP API, but are purely PyFemap (Python) functions created to make Python behave syntactically similar to the FEMAP API.

It did the trick! It works perfectly now.

Thank you very much, Nick!

Best regards,
