When I execute Fluent from the start menu, it only starts when I do not load any case or mesh data, otherwise, it just closes without warning.nThis was not happening before. It started to happen when I was trying to use UDF functions and the compiler wasn't working, so I tried starting it from the command line. After that, it never opened with mesh or case files again. Fortunately, it still opens the files after it starts and from the workbench.nI am mostly just annoyed by the issue, any idea how to fix it?n

Hello,nAfter you launch Fluent, try and start writing a transcript file. This can be found under: File -> Write -> Start Transcript.nNow, read your case and data files. After the Fluent session closes, look into the saved *.trn file to see if there are any error messages printed.nAlso, is this an issue with a specific case & data file or are you seeing this behavior when you read any generic case and data files?nKarthikn

Thanks for the suggestion. This happens with any case or mesh file. nI tried it and didn't see any issues in the .trn file, but still Fluent didn't open:nBuild Time: Dec 2 2019 14:15:26 EST Build Id: 10114 nExecutable Path: C:/PROGRA~1/ANSYSI~1/v201/fluent/ntbin/win64/fluent.exenn-------------------------------------------------------------------------------nID  Hostname  Core O.S.     PID  Vendor           n-------------------------------------------------------------------------------nn3  DESKTOP-T1 4/8 Windows-x64 24708 Intel(R) Core(TM) i7-9700K nn2  DESKTOP-T1 3/8 Windows-x64 21276 Intel(R) Core(TM) i7-9700K nn1  DESKTOP-T1 2/8 Windows-x64 9636  Intel(R) Core(TM) i7-9700K nn0*  DESKTOP-T1 1/8 Windows-x64 23196 Intel(R) Core(TM) i7-9700K nhost DESKTOP-T1    Windows-x64 18880 Intel(R) Core(TM) i7-9700K nnMPI Option Selected: ibmmpinSelected system interconnect: defaultn-------------------------------------------------------------------------------n(cx-gui-do cx-activate-item MenuBar*WriteSubMenu*Case...)n(cx-gui-do cx-set-file-dialog-entries Select File '( Apr13.cas.h5) CFF Case Files (*.cas.h5 ))nFast-loading C:\PROGRA~1\ANSYSI~1\v201\fluent\fluent20.1.0\\addons/afd/lib/hdfio.binnDone.Note: Choosing I/O mode NODE0 as default automatically.nnWriting to DESKTOP-T1:/OneDrive - University of Toronto/Documentos/COURSES/FOURTH YEAR SECOND SEMESTER/MIE504/Apr13/Apr13.cas.h5 in NODE0 mode and compression level 1 ...n Writing mesh ...n   118262 cells,   3 zones ...n   367305 faces,  14 zones ...n   130890 nodes,   1 zone ...n Done.nDone.n(cx-use-window-id 1)n(cx-gui-do cx-activate-item MenuBar*FileMenu*Exit)nnPosting ANSYS Product Improvement Program performance data nDone.

Hello,nHow are you opening the case file again? Can you detail out the steps?nKarthikn

Open Fluent from Windows Start Menu -> Load Case/Mesh -> Click Start With Selected Options (3D, double precision, 4 processes) -> Fluent Crashes without warningnOpen Fluent -> Start without loading any files (3D, double precision, 4 processes) -> Read Case -> WorksnOpening Fluent from Workbench worksn

It might be related to /OneDrive - University of Toronto./etc I get some weird issues with OneDrive and the drive mapping I need to use because someone thought adding a comma into the path was a good idea..... n
