Energies from thermal analysis are listed in available results but cannot be obtained

[vymlatilp]

Hello,

there are energies listed in avaiable results of thermal example. How ever if we try to obtain them, an error occures, see below.

Code:

file_path = Path(r"03_thermal_steady_state.rth")
model = dpf.Model(file_path)
print(model.metadata.result_info)

Output:

 Static analysis
Unit system: SI: m, kg, s, V, A, K
Physics Type: Thermal
Available results:
     -  temperature: Nodal Temperature
     -  heat_flux: ElementalNodal Heat flux
     -  element_nodal_forces: ElementalNodal Element nodal Forces
     -  elemental_volume: Elemental Volume
     -  stiffness_matrix_energy: Elemental Energy-stiffness matrix
     -  artificial_hourglass_energy: Elemental Hourglass Energy
     -  thermal_dissipation_energy: Elemental thermal dissipation energy
     -  kinetic_energy: Elemental Kinetic Energy
     -  co_energy: Elemental co-energy
     -  incremental_energy: Elemental incremental energy
     -  structural_temperature: ElementalNodal Temperature
     -  heat_flux: ElementalNodal Heat flux

Code:

from pathlib import Path
from ansys.dpf import core as dpf
file_path = Path(r"03_thermal_steady_state.rth")
model = dpf.Model(file_path)
result = dpf.operators.result.stiffness_matrix_energy()
my_data_sources = model.metadata.data_sources
result.inputs.data_sources.connect(my_data_sources)
print(result.outputs.fields_container())

Error:

ansys.dpf.gate.errors.DPFServerException: ENG_SE:0<-Source operator "mapdl::rth::ENG_SE" not found

Similar errors we obtain also for other energies.

Could you please help us with the error? Or if the energies are not valid for thermal analysis, could you remove the energies from available results?

Thank you and best regards,
Petr
