Description of the bug

Hi,
I read the contact results for certain nodes. It works very well, but if I change the location of contact detection points using Keyopt(4) for CONTA174 to 3 or higher, then no contact results are available (zero entities).

Could you help on this?

Steps To Reproduce

ID_STEPS=dpf.time_freq_scoping_factory.scoping_on_all_time_freqs(MODEL)
ID_NODES=dpf.Scoping(ids=list(DATA_CONT[:,0].astype(np.int64)),location=dpf.locations.nodal)
RES_CS=dpf.operators.result.contact_status( data_sources=MODEL,time_scoping=ID_STEPS,mesh_scoping=ID_NODES,bool_rotate_to_global=False).eval()
RES_CP=dpf.operators.result.contact_penetration( data_sources=MODEL,time_scoping=ID_STEPS,mesh_scoping=ID_NODES,bool_rotate_to_global=False).eval()
RES_CG=dpf.operators.result.contact_gap_distance(data_sources=MODEL,time_scoping=ID_STEPS,mesh_scoping=ID_NODES,bool_rotate_to_global=False).eval()

Hello @GitHubUser120282 ,

It turns out this very issue has been solved for DPF in ANSYS 2024 R2. Is it possible for you to change ANSYS version?
If not, you will be able to get this fix by using the 2025.1.pre0 standalone version of DPF available starting next Thursday, July 25.
Here is how you will be able to get it and use it: https://dpf.docs.pyansys.com/version/stable/getting_started/dpf_server.html
