Dear Toufik,<br>
are you sure it stopped? Maybe it's just much slower than you
expect.<br>
<br>
And about the memory, the disk space is not really important, even
cheap laptops have enough disk space to run any simulation. What
matters is available RAM memory, do you have plenty of it?<br>
<br>
regards<br>
