Prior to version 9.5.1 the engine did not validate the names of pseudo-components and names with [] passed when used for HYSYS. The new version validates names for the first character alpha A-Za-z and all subsequent characters A-Za-z0-9_ with a max length of 11.

Updated name validation to allow [] in the 2-11 characters in the name

During testing 9.3.2 I found that a file opened from previous version of HYSYS does not work properly in the newer build that its opened in. If I go to input and change the temperature for the stream, I see Gibbs minimization error in the summary window. .hsc file is attached

Problem happens with clients having FULLACCESS security in Hysys, Security is initialzied during DBS generation but uninitialized during problem run, causing the engine to read CONFUSED values for some parameters. This is fixed by initializing security correctly

Bug Description
2955(11758)

Model generation is incorrect using MSE with a private databank. In investigating this case I created a fluid package using the latest AMINEHCL databank.  When the private databank was used it was found that the PUBLIC databank was used along with AMINEHCL.  MSEPUB should have been used instead. 

Add code in psauto.exe and olgen.exe to check databanks consistence:

1. for psauto.exe, check if private DBs are consistent with the master DB

2. for olgen.exe, except check DBs consistence, it also check if the DBs are consistent with the keyword(MULTEQ2 for msepub) in the MOD file.

error message will prompt out in PSAUTO and program stops. In OLGEN, error message will send to the WRN file. (HZ)
