EnSight provides a mechanism for users to write their own readers and have the code automatically link and execute at run-time (using a shared library).This capability is documented in the Ansys EnSight Interface Manual. As indicated in that manual, sample readers, as well as the code for several actual readers are provided below the following directory: $CEI/ensight242/src/readers/. In subdirectories underneath, there may exist other README files that contain additional information on using existing user defined readers.

Also, as explained in that manual, be aware that a udr_checker.c file is provided in $CEI/ensight242/src/readers/checker directory. This can be used to debug your User-defined reader before using it with EnSight.
