Normally material studio, save the calculation and structure file at the time of interpretation. From the resultant structure file, we can start the calculation.

Thanks, but when the internet suddenly down, how can continue our program? Because my program take 2 months and then I miss all of them.

Shideh,

you've make active the created .xtd file of your simulation. then from the performed calculation box for the program which interrupted suddenly you could restart your program. Make sure to check the restart box at the bottom of the calculation box, and reset ur simulation time.

hope this helps,

Sheida
