Hi,

I have a model in which four reference points are used for boundary conditions and which are connected to the model by "couplings". Abaqus makes nodes at these reference points with the labels 1, 2, 3 and 4.

I am trying to make a node set for these points in a Python code: 

.....

nLabels = [1,2,3,4] # Probing these nodes in post reveals that they belong to part instance "ASSEMBLY"

nodeSet=odb.parts['ASSEMBLY'].NodeSetFromNodeLabels(name='BC NODES',nodeLabels=nLabels)

.......

The last line gives an error: "OdbError: Entity has no mesh"

Any ideas how the solve this issue?

Any other methods to access nodes in reference points not being meshed? –The use of these nodes is to examine the reaction forces and to calculate the total reactions.

Thanks
