CFX Solver Manager ended with Error

tct371 · August 9, 2018, 05:17

Hi guys,

The design that i want to simulate is a U shape oscillating water column. I have simulated my design before and it works but when i repeat it again with different parameters but still with the same scale (just change some parameters) it shows error at the cfx solver manager.

Is there solution for this problem?

Thanks

The error is as below:

i have rerun it several times but it still crash with this error. for the disk space is it the hard disk space( local disk C)? if yes I have plenty of disk space available

ghorrocks · August 9, 2018, 06:28

I have never seen that error before so do not know what is causing it.

Do you get it if you change to serial, local parallel or distributed parallel? Or different parallel implementations (Intel MPI etc)?

If that does not help please post your CCL.

Hi

i used intel mpi local parallel before this and this is my ccl

I cannot see anything obviously wrong there, it looks like a pretty standard setup.

Try regenerating your def file in CFX-Pre. To speed things up you can import the CCL you just posted so it sets it all up in one go. Maybe you have a def file with some weird form of corruption.

tct371 · August 9, 2018, 07:34

May I know how to regenerate the def file? Or it means that I just need to redo the setup?

ghorrocks · August 9, 2018, 18:16

Just redo the setup.

Opaque · August 15, 2018, 12:06

Does it happen at a specific timestep? Can you try writing a transient file every timestep to isolate the state of the model from other things?

For example, writing the file for the initial timestep even before the model is discretized and solved.

Use another option for the file, say Essential, or Minimal? If the behavior changes, the file is being corrupted by the writing process of a quantity used in your model.

Let us know, and hopefully, we can help.

tct371 New Member Join Date: Aug 2018 Posts: 5 Rep Power: 7	Hi guys, The design that i want to simulate is a U shape oscillating water column. I have simulated my design before and it works but when i repeat it again with different parameters but still with the same scale (just change some parameters) it shows error at the cfx solver manager. Is there solution for this problem? Thanks The error is as below: \| Writing transient file 27_full.trn \| \| Name : Transient Results 1 \| \| Type : Standard \| \| Option : Every Timestep \| +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ \| ERROR #001100279 has occurred in subroutine ErrAction. \| \| Message: \| \| create_indextable: stored index is wrong: missing start tag \| \| \| \| \| \| \| \| \| \| \| +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ \| ERROR #001100279 has occurred in subroutine ErrAction. \| \| Message: \| \| iif_open: unable to read the stored index, attempting to rebuild \| \| it \| \| \| \| \| \| \| \| \| +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ \| ERROR #001100279 has occurred in subroutine ErrAction. \| \| Message: \| \| recreate_indextable: warning: file was not closed correctly, data \| \| may be inconsistent \| \| \| \| \| \| \| \| \| +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ \| ERROR #001100279 has occurred in subroutine ErrAction. \| \| Message: \| \| create_indextable: stored index is wrong: missing start tag \| \| \| \| \| \| \| \| \| \| \| +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ \| ERROR #001100279 has occurred in subroutine ErrAction. \| \| Message: \| \| iif_open: unable to read the stored index, attempting to rebuild \| \| it \| \| \| \| \| \| \| \| \| +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ \| ERROR #001100279 has occurred in subroutine ErrAction. \| \| Message: \| \| cfxreadString: read too many characters: A \| \| \| \| \| \| \| \| \| \| \| +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ \| ERROR #001100279 has occurred in subroutine ErrAction. \| \| Message: \| \| recreate_indextable: dataset length of zero in dataset at offset \| \| 47942198 (format FR): assuming incomplete file and terminating sc- \| \| an. \| \| \| \| \| \| \| +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ \| ERROR #001100279 has occurred in subroutine ErrAction. \| \| Message: \| \| iocnt: open the primary file failed \| \| \| \| \| \| \| \| \| \| \| +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ \| ERROR #001100279 has occurred in subroutine ErrAction. \| \| Message: \| \| OpenFile: open primary file failed \| \| \| \| \| \| \| \| \| \| \| +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ \| ERROR #001100279 has occurred in subroutine ErrAction. \| \| Message: \| \| Stopped in routine OpenFile \| \| \| \| \| \| \| \| \| \| \| +--------------------------------------------------------------------+ End of solution stage.

Do you get it if you change to serial, local parallel or distributed parallel? Or different parallel implementations (Intel MPI etc)? If that does not help please post your CCL. __________________ Note: I do not answer CFD questions by PM. CFD questions should be posted on the forum.

Try regenerating your def file in CFX-Pre. To speed things up you can import the CCL you just posted so it sets it all up in one go. Maybe you have a def file with some weird form of corruption. __________________ Note: I do not answer CFD questions by PM. CFD questions should be posted on the forum.

Opaque Senior Member Join Date: Jun 2009 Posts: 1,804 Rep Power: 32	Does it happen at a specific timestep? Can you try writing a transient file every timestep to isolate the state of the model from other things? For example, writing the file for the initial timestep even before the model is discretized and solved. Use another option for the file, say Essential, or Minimal? If the behavior changes, the file is being corrupted by the writing process of a quantity used in your model. Let us know, and hopefully, we can help.
