I write a script to simulate stress and deformation.  
The “problem” command is used in this script.  
It is successful to perform the script by command line:  
“FreeFem++ scriptname.edp”

But I can not understand the output information:  
two minimum and two maximum number is printed on screen.

Are they calculation errors of variable?  
Where could I find the calculation error of the variables?

Thanks for everyone’s help!

No, it’s just the minimum and the maximum of the solution. You can remove them with the additional command-line argument `-v 0` when you launch your script (or `verbosity = 0;` directly in your .edp).
