Description of the bug
We encountered an issue when using DPF to extract results from the .rst file SS_assembly_10_therm.rst. While native ANSYS software shows seven different result types (e.g., stress, displacement, temperature, etc.), DPF returns only mesh data — no result types are reported.
Steps To Reproduce
import os
from ansys.dpf import dpf
filepath = "SS_assembly_10_therm.rst"
ds = dpf.DataSources()
ds.set_result_file_path(filepath, key="rst")
model = dpf.Model(data_sources=ds)
available_results = model.metadata.result_info.available_results
print(available_results) # Output: []
The file is of bigger size(around 6gb)
Expected: A list of available results such as displacement, stress, temperature, etc.
Actual: An empty list — no results found.
This suggests DPF is failing to recognize or load the result types, even though the data is present and viewable in ANSYS Workbench or Mechanical.
Please advise on how to resolve this — or let us know if this is a known limitation with thermal .rst files.
