MT-MECH - New Releases

The following MT-MECH programs have been upgraded:

MT-COMP
MT-VESS
MT-EXCH
MT-LAYOUT

The major improuvements concern the Material Data Base where a complete revision of ASME materials has been done for ensuring compliance with ASME II - Part D Addenda 2002 and the harmonization of the ISPESL-VSR and AD-MERKBLATTER codes with the European PED directive.
Trough a new developed interface MT-EXCH/LAYOUT programs can now directly import thermal data coming from calculations performed by the HTRI program Xist.
For a complete list of the new releases contents see the tables herebelow each one specific for a program.
