      When applying a rough-wall condition on General Grid Interface (GGI) non-overlap regions the releases 2020 R1 and R2 will result in the following error: Error detected by routine PEEKCS CDANAM = HOW CRESLT = NONE Current Directory : /FLOW/BOUNDCON/ZN5/BCP38/NOVARIABLES/RGH This issue is fixed for 2021 R1. For release 2020 R1 and R2 it can be worked around by using the attached tt-file. To make this tt-file available to CFX the environment variable CFX5_TT_FILE must be set to the tt-file, including the absolute path to the file.
