After entering data into Load> Time History Location dialog screen, and press the apply button the Scale column automatically updates to 90.000 for all points, pressing apply again, all values for DX are updated to 90.000, pressing apply more times eventually updates all the values to 90.000 in the dialog. Why?
Close the model and confirm that both the Time history load name (*.THL) and Time History file (*.TIH) meet the file naming requirements.
Copied from the online help:
The following file types which typically do not have the system name as a prefix, will continue to be limited to 8 characters.
Load data files (*.SPC, *.THL, *.TIH, *.HMF)
Unit files (*.UNT, *.UNI)
Library files (*.LIB)
The following set of characters are not allowed in the model file name
1. / \ : " * ? < > |
2. Non-Ascii characters (ANSI character codes less than or equal to 31).
In addition, blank spaces are NOT allowed in these file names. After fixing the file names, reopen the model and reassign the time history file in Load> Time history location dialog screen. After making these changes, notice that hitting the "Apply" button does not change the values in the dialog screen as had happened before.
