FLUENT can not read data file
 

Hi All, I am getting problem while reading a data file. Reading the case file is successful, but when I am trying to read the data file, FLUENT would be frozen with the Message "Reading......dat.gz...", and it remains such a state for one day!So the data file can not be imported.
I am working on a cluster with parallel calculation. And the size of one data file is about 80M. Can anyone help me ?

thanks all.
