You made it so simple. Next-In Input Manager released by Never Gray for SES/SVS is lucid, easier to work and with great user interface. As I was also a beta tester for Next-in I myself validated input generated by Next-In. We at SYSTRA have used the Next-In Input manager for few recent projects and it worked well.  My experience was positive and unsurpassed.

I started using the spreadsheet and it is a time saver.

The spreadsheet without software restrictions for a license.  The VBA source code can be viewed and edited.


Update to 2.5 from 2.4

​Simulations use the latest version of SES 6.0, executable "SESV6_32.exe". Continue using version 2.4 if you are still using the executable named SVSV6_32.exe.

Update to 2.4 from 2.3
  1. Form 11A Automatically calculates the number of segments in 11B.

  2. Initialization File names longer than 80 characters can be read in from input files.

  3. "Last Read" and "Last Wrote" on the control sheet include the date and time.
