📝 Steps to reproduce
run below commands to reproduce;
import ansys.fluent.core as pyfluent
from ansys.fluent.core import examples
solver = pyfluent.launch_fluent(insecure_mode=True)
mesh = solver.results.graphics.mesh
case_file_name = examples.download_file(
"mixing_elbow.cas.h5", "pyfluent/mixing_elbow"
)
with pyfluent.BatchOps(solver):
solver.file.read(
file_name=case_file_name, file_type="case", lightweight_setup=True
)
mesh["mesh-1"] = {}
assert not solver.scheme.eval("(case-valid?)")
assert "mesh-1" not in mesh.get_object_names()
then run assert statements;
assert solver.scheme.eval("(case-valid?)")
assert "mesh-1" in mesh.get_object_names()
