Error writing compressed file during auto save
 

Hello everyone, I'm having a problem when using the autosave function in Fluent v13. I have it installed on my laptop (Vista), and the calculations run fine, but the program stops and gives me the error when it does auto save saying

Error: error writing compressed file
Error Object: #f

Any suggestions as to why this is happening and what the solution is? :confused: I would really appreciate it. Thanks!

Hi. It could be due to the path root name. e.g. if the folder name where your are working has a 'strange' character, like ?,!,",ñ,etc. try to rename your folders. Hope this help

Regards

Hi,

It also happens when your hard drive is full, or if you don't have the correct rights on the folder.

Marion.

Also, are you writing to a local disk or server? This has caused me angst in the past.

Thanks for the replies. It's not a new file, just a new version of Fluent (upgraded from 12) and I'm on a laptop now with admin account on Vista. Working dir is my flash drive (G:) and so is my saving location. No funny characters in the directory (except underscores). I have tried changing my save location to D:drive, but no difference.

This is what appears in the pop up box
Error writing "| gzip -2cfv > J:\MZ\turbine_closed_files\dp0\FLU-2\Fluent\SYS-3-01205.cas.gz".

I am also facing the same problem. If any one has found solution to this problem then please help...

Did you run Fluent in parallel? In my experience some user created geometry (points, planes, etc.) could cause problem in parallel mode. Try cleaning those geometry and rerun. You should also try to write the file uncompressed to see if it helps to avoid the error.

Hi
I am getting the error too...

Error writing "| gzip -2cfv > C:\Users\IITm\Documents\sneha_trial2_files\dp0\FFF \Fluent\FFF.1-24-00600.cas.gz".

i am using 'series' only. And the drive doesn't seem to be full. And no spl characters are involved. the calculations were gng fine... but in half way, I got this error. plz help.

By 'series' you mean serial mode? The error message only has 1 line?

Ya ya ... That line followed by
Error Object: #f
But i think i ve got the solution ... Will get back with it once I am sure it works...:)

Power options setting in the PC should be changed to overcome this error. Set 'put computer to sleep' as 'never', and then in 'change advanced power settings', click on 'hard disk' and set 'turn off hard disk after' to 'never'. Also ensure that in the 'sleep' option, 'sleep after', 'allow hybrid sleep', and 'hibernate after' are set as 'never' ...

gzip error
 

Even I have got the same error as gzip-2cfv while running supersonic flows in fluent.Can any one suggest me regarding this

Thanks
 

It helped me...... :) :)

I am facing the same problem and inspite of changing power settings as mentioned earlier, I am not able to get rid of this error.

Do you have a problem with saving in general or autosave?
The power settings turns off the hard disk after # minutes so that Fluent cannot write to the disk and hence throws the error during a simulation. If you don't have an autosave problem then the power settings don't make a difference. If you're saving over a network drive then make sure your network doesn't go to sleep.

Check to make sure you have write permissions etc in that directory and that your disk is not full.

And try saving uncompressed files to see if you still have the same issue (usually the problem isn't because of the compression so normally you do have the same problem).

I've encountered the same problem when i tried to calculate. When i tried to close Fluent the same problem faced me..

Error: Error writing compressed file "FFF.1-Setup-Output.cas.gz"
Error Object: #f

I solved the problem by the following procedure;
1. I had to force Fluent to stop (Task manager >Select (Fluent) > End Task)
2. 'Archive'/'Save As' the project from the workbench to other directory and run Fluent from this directory.

Error in Fluent15

Error: Error writing compressed file "FFF-Setup-Output.cas.gz"

Found solution to error writing gzip
 

Hey guys,

So all of the above solutions did not work for me but I found a fix!!!
I think this could be an issue with people on windows 10 but not sure.
Basically i realized that my gzip.exe was also crashing when I recieved the error, so i went into the fluent folder and found the gzip.exe and did a simple test to see if it would work in cmd. Basically i tried to gzip a text file and found that it crashed!! Yureka! So this told me that the gzip.exe file itself was corrupt or not compatible with windows.

So I went to: http://www.gzip.org/gzip124xN.zip
Got the new gzip.exe and replaced this one with the one installed in my ansys folder at C:\Program Files\ANSYS Inc\v170\fluent\ntbin\win64 and overwrote the gzip.exe.

Now everything works!!!
If this helped you, please consider checking out and subscribing to my youtube channel at:

Found solution to error writing gzip
 

hey guys.

here is the solution.

go to: http://www.gzip.org/gzip124xN.zip

download the file. copy and paste gzip.exe at

C:\Users\admin\AppData\Local\Temp

it's working. all the best.

Thank you Drdalyo, this worked for me:

I have problem "loading" .gz files on Windows 8 and 10, also saving them in .gz format. I replaced both gzip.exe and gunzip.exe files with the new "gzip.exe you provided" and rename one of them back to gunzip.exe [in C:\Program Files\ANSYS Inc\v170\fluent\ntbin\win64]

This was a perfect solution!Thanks! :)

Great it helped :)

asking solution of gunzip.exe problems
 

Hi all,

I have other problems when I am reading my running file. gunzip.exe does not work. Can you give me the solution? I am using Ansys Fluent 17.2 in windows 10.

Thank you

Best Regards

Error on reading gunzip file
 

Dear all,

I am trying to open the file of my previous simulation. I am using FLUENT 17.2 in Windows 10. I have problem in opening due to gunzip.exe doesn't working while opening. Can you tell me the solution of problem?:confused:

here is the warning

Thank you so much

on overwriting the gzip.exe
 

Hi Drdalyo,

Did you mean overwrite the gzip.exe in the Ansys folder with the gzip.exe you downloaded from http://www.gzip.org/gzip124xN.zip?
Sorry, I got the opposite impression from your explanation and got confused.

Error locating http://www.gzip.org/gzip124xN.zip
 

There is an error when i click on the link http://www.gzip.org/gzip124xN.zip
It reads " Not Found
The requested URL /gzip124xN.zip was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. "

Please help me in the direction.:confused::confused::confused::confused:

Just go to gzip.org which will link you to the gnuzip page

Should the entire .zip folder has to be or just the .exe files?
If so cant find any .exe files.


Please help

Could anyone post a link for gzip.exe file, All the other folders are in .zip folder. Can't find .exe file.

Thank you

gzip
 

Why do you need gzip? It is automatically installed with Fluent and is available at same location as fluent.exe in Windows. Linux has it preinstalled.

The preinstalled version is crashing. I need new gzip.exe and gunzip.exe.

Crashing
 

What do you mean by crashing? You cannot use these files by standard double clicking approach Windows follows. These can only be used via command or by Ansys tools that are linked to it. You can re-install Ansys to get it back.
