How can I obtain the structural moment components for beam elements in PyDPF?
(The result where Item corresponds to M in the APDL command PRESOL)
The element_nodal_forces operator only returns force components.

Ryoma

The element_nodal_forces operator has an option called split_force_components.

Setting this to True outputs results with the translational and rotational components separated. Among these, the one with dofs=1 corresponds to the rotational component, i.e., the moment.

For details on the operator, please refer to the following:

element_nodal_forces — PyDPF-Core

Sample code:

# read file result information with pyDPF

from ansys.dpf import core as dpf




# Define the path to the result file

result_file_path = r"file.rst"



# Load the result file into a DPF model

model = dpf.Model(result_file_path)


op = dpf.operators.result.element_nodal_forces()

op.inputs.data_sources.connect(model.metadata.data_sources) 

op.inputs.read_beams.connect(True)  

op.inputs.split_force_components.connect(True) # outputs force and moment components separately

moments = op.outputs.fields_container()[1]  # Get the moments field

print(moments)
