Issue with the results after applying prescribed nodal value

Dear Team,
I tried to apply 10mm settlement at one end of an arch barrel by assigning a nodal value of -10 at the nodes. However, the results show a displacement magnitude of only 0.41mm. Despite setting a 10mm settlement, the results do not reflect this value, and settlement is not shown in the postprocessor even when I adjust the deformation scale. Additionally, I received the following warning:
WARNING: PlainHandler::handle () - non-homogeneous constraint for node 3, homogeneous constraint assumed.
and I've also uploaded the screenshots of it. Could you please assist me in resolving these issues?
Thank you.

Hi, "Plain" constraint handler cannot enforce non-homogeneous (non-zero) constraints directly. That is why the warning was given before the analysis mentioning that homogeneous (zero) constraints is assumed. So, you can use either "Penalty" or "Transformation" or "Lagrange" constraints in the analysis settings.

Thank you for your time and response sir. Despite setting a 50mm settlement, the results do not reflect this value in the postprocessor and the values are very high. Additionally, I received the following after 6th increment

Can you share your file?

Don't worry, this is not an error, is just a warning with the new version of HDF5 library (before this warning was not printed)
