I have a umat1.bin file from a prior version of CAESAR II (we're now using 5.3). So I go to find the \System directory so I can copy it into it, renaming it umat1.umd, but there is no \System folder. It's not hidden. Ideas?

I tried creating a directory named "System" and placing the file in it but the materials I was after didn't display in the material drop down box on the CAESAR II input screen, even after I closed CAESAR II and re-launched it.

Try with below path, it may work.

C:\Documents and Settings\All Users\Application Data\COADE, Inc\CAESAR II\5.20\system

Hope you will find your required directory.

Note that the above path is valid only for Windows XP. For Vista and Win7 you want this:

c:\program data\COADE, Inc\CAESAR II\5.20\system


Also note that as of Version 5.30 "COADE, Inc" has changed to "Intergraph CAS".

Thanks guys - that did it!
