HL support spice model, so normally transmisson line's W Element model cab be used in HL linesim. I don't know what format is intel .rlc file. You can check below example for W Element modle and create the transmision line 's element model based RLGC valued in .rlc file of intel.
You can add a package/connector symbol in schematics and assign the model you created to it.

Yanfeng is correct. Let me add a few details to make it easier for you. Notice in Yanfeng's example, the SPICE file contains a .subckt and an instance of the W element in that subcircuit. Your SPICE model must be in the form of a subcircuit, so that HyperLynx can instantiate it.
Also, HyperLynx will only show files with certain file name extensions when you browse for the model file. Select menu Setup > Options > General... select tab Circuit Simulators and see the frame titled SPICE-deck file extensions. You can either change your model file name to have one of the listed extensions, or add your file name extension into this list.
Hi Yanfeng and Weston,
Many thanks to both of you for your help.
I was able to "import" the .rlc file through a sub-circuit and add it to my model.
Thanks a lot.
