Exporting an ensight case gold file from fluent works well. However, with large simulation, the export process adds many hours onto the simulation time. I found that ticking the “EnSight Parallel” option in the fluent export window speeds up the process considerably.
However, I cant find a way to load the files into EnSight (2020.r2) without fatal errors. Fluent creates a subdirectory with as many .encas files as there are cpu cores. (cnode_0.encas , cnode_1.encas etc) If I load the set of encas files by specifying “cnode_*.encas” as the filename, I get the following error:- Error ERROR: Error> {s1:1} readensight_file_descrip() in geom.c:1215 of EnSight Server 2020 R2: Error ERROR: ensight error; type=Error no= 3 (00000003) Error ERROR: Reading geom file description line Error ERROR: Error reading data. Error from dr_do_read2(). If I use the “multiple file interface” button and add to list “cnode_*.encas”. I get the same error. As I am trying to perform a task that practically everyone else needs to do, I can only imagine there is some step I don’t know about. Should this method work ? Perhaps “ensight parallel” is not supported with moving meshes ? Any advice would be appreciated. |

This is just some house cleaning for others who (like myself) were struggling with the EnSight transient import issues. The OP did find a solution on the ANSYS Learning forum, which is honestly surprising given my experience with that forum.
Anyway, the full answer can be found here: https://forum.ansys.com/forums/topic...t-simulations/ The short answer: Beware unticking the box that says: Separate files for each Time Step |
