How to get plate thickness based on element id?
Hi everyone,
I have a plate model with several plates of different thicknesses. In postprocessing I'd like to know the thickness of an element based on its id. Does anybody know how to calculate/retrieve it?
from ansys.dpf import post simulation = post.load_simulation('file.rst') elemental_stress = simulation.stress_eqv_von_mises_elemental() selection_ids = elemental_stress.index[0].values selection_id_0 = selection_ids[0] # How to get the thickness of the selected element? print(selection_id_0)
Thank you!

I currently use the dpf
op = dpf.operators.result.mapdl_section() # operator instantiation op.inputs.properties_name.Connect("Thickness") op.inputs.data_sources.Connect(data_source) mmv = op.outputs.properties_value.GetData()

Hi Peter,
Thanks for your quick answer.
I changed theConnect
toconnect
in your line 2 because I was getting this error:AttributeError: 'properties_name' object has no attribute 'Connect'
Now my code looks like this:
from ansys.dpf import post from ansys.dpf import core as dpf simulation = post.load_simulation('file.rst') elemental_stress = simulation.stress_eqv_von_mises_elemental() selection_ids = elemental_stress.index[0].values selection_id_0 = selection_ids[0] op = dpf.operators.result.mapdl_section() op.inputs.properties_name.connect("Thickness") op.inputs.data_sources.connect(data_source) mmv = op.outputs.properties_value.GetData()
Now I'm getting this error:
op.inputs.data_sources.connect(data_source)
NameError: name 'data_source' is not definedJust to be sure we're talking about the same thing: I have an rst file I wish to analyze outside of the workbench environment. I think that might be causing the
data_source
error?0 -
Hi both!
@Peter seems to be using Mechanical DPF (Iron Python convention -hence the capital C in Connect) whereas @Nathanvanthof you are using PyDPF (CPython convention - hence small c in connect).
@Nathanvanthof , you've referenced your result file to use in DPF Post line 4, but starting from line 9 it is DPF Core that you are using. The error message with missing data_sources is that you have not linked your result file here.0 -
Hi Nathan,
as @Pernelle Marone-Hitz mentioned I am using Iron Python within mechanical.
The data_source error is not causing the error because it is outside from mechanical, it is because it is not defined.0
