Tracking down variables which changed sign

Since June 2009, ViewHAR has been able to display SL4 solution files in a manner similar to ViewSOL -- except that (unlike in ViewSOL) you can see values for variables with 4 or more dimensions. See Opening SL4 solution files.

In this case, the Contents page contains a "<-100" column which counts how many values are less than -100. This may help you notice % change variables which changed sign.

However, for huge, many-dimensional, variables it might be difficult to discover exactly which elements changed sign. In that case, you should right-click the variable from the Contents screen and select the Properties option -- at the bottom of the properties window, the [first 50] elements<-100 will be listed.
