      This problem occurs when an older Fluent Meshing workflow file is used/modified in a newer release. Older releases did not support periodics, so the strange error is generated. Meshing Workflow files are read in with an attempt to stay true to older releases, which is why these issues can crop up. If you are setting up from a brand-new import with Fluent Meshing 2021R1 you will not see this problem. To fix: You can check the meshing version number of the workflow file in Fluent Meshing with the scheme call below. (be sure to include the brackets): Meshing> (meshing-wf-get-version-number) 19.4 Then, change the version number that Fluent Meshing “sees” to your current release: Meshing> (meshing-wf-set-initial-version 21.2) () (This should allow the periodics to be created)
