that helps me thank you but II still have this error message:

"Error creating wall transfer function coefficients: unable to find a root
after indication that a root exists. Maybe timebase is too small"

my inf file's end is:

             ---------- WALL TYPE PORTE               ----------

 UNABLE TO FIND A ROOT AFTER INDICATION THAT A ROOT EXISTED

 CHECK THE WALL TYPE AFTER THE LAST CALCULATED WALL
 OFTEN THE WALL CAPACITY IS TO SMALL TO CALCULATE A TRANSFER FUNCTION !

 CHECK ALSO YOUR TIMEBASE !


Do you or anyone have an idea of what I can do to avoid this error?

Thank you for your help
