When I use ansys meshing in linux machine, I get this error message (The process suffered and unhandled exception or ran out of usable memory). RAM in linux machine should be enough. But, I can mesh the same geometry by using windows machine with much less RAM.

It seems ansys meshing create large temporary file to my home directory (which has limited size). '.ansys' file?

Could you give suggestion how to move the large temporary file to another disk place?

Thank in advance!

Are you sure that .ansys is a regular file, not a directory?

You can try to create a directory called .ansys on any disk where you have enough space and create a symbolic link into your home directory.

Thank you very much!

Your are right '.ansys' is a directory.

Could you give a simple example of this symbolic link?

[jhns]

Of course.

first, move .ansys to a place where you have enough space by opening a terminal and type in:

mv ~/.ansys /media/some/big/disk

change into your home directory:

cd

then you can create the symbolic link with

ln -s /media/some/big/disk/.ansys .ansys

Thanks a lot!

I tried the link as you suggested. But it still writes the file to /home/.ansys directory. Not to the big disk.

[jhns]

If you execute

ls -al ~/.ansys

does it show .ansys as a directory or a link?

if it's a link, the first part of the output should look like lrwxrwxrwx

if that's the case, you will see the files inside there but they are stored on your large storage device.

You can check the disk usage with

df -h

.ansys is a directory. I can not remove all the hiden file in this directory.
I want to remove all the files, and delete this directory. Then to have a link. But I do knot know how to do it.

[jhns]

to delete the directory .ansys and all data in it

rm -rf .ansys

create a new .ansys directory somewhere else

mkdir /place/for/new/.ansys

create the link

ln -s /place/for/new/.ansys .ansys

for all commands I assume you are in your home directory

hope that helps

Hey,

I encountered that problem before on Windows, try right-clicking on the mesh in the work tree, and there should be an option similar to "clear the mesh data". That will free up those memories and you can create the mesh again.

This operation can help, but non always. In my case I was able to mesh the domain only deactivating the automatic proximity refinement.
