Hey, I've got a problem. I begin the calculation. After a while, when the autosave is supposed to run, Fluent writes me that it can't write the files cas and Dat. Then , i've intented to write manually but another message happened : can't read directory!!

First of all, I've thought about a problem of memory but in fact it is not. So if you have some idea about it, don't hesitate. Sam

maybe your autosave directory is write protected or there is no free space on drive.

In fact it was my udf which was wrong. Thank you, Laszlo.
