Release of MemsONE Version 4.0(4) Enhanced functions and expanded data in the material
databasea. Enhanced the function that allows characteristic data of specified
materials to be referenced and recorded together in a table.

Upon the release of version 1.0 of MemsONE (Computer
Aided Engineering System for MEMS) in February 2008,
the Micromachine Center initiated activities to disseminate
MemsONE throughout Japan. For the past three years, we have
kept up these dissemination activities using such catchphrases
as “an analytical tool providing powerful support for MEMS
design and manufacturing processes” and “a tool suitable bothfor experts and novices with little experience in MEMS.” During
this period, versions 1.1, 2.0, and 3.0 of the product werereleased, each release offering enhanced and more powerful
functions with greater stability.
Version 4.0, anticipated for release in February of this year,
will have even more improvements in analysis capabilities, userfriendliness, and the operating environment. The following aresome of the improvements and enhanced features in version 4.0.

b. Added supplemental characteristic data for piezoelectricmaterials (particularly matrix data) required for piezoelectric
analysis.

(1) Added support for Windows 7
MemsONE can now be used in the Windows 7 environment.
The program was tested on various models of notebook anddesktop computers to identify any issues. Recommended
computer specifications are clearly noted in the product.

(5) Improved and enhanced pre-process functions
a. Added a function to compute mass properties (area and volume).
b. Improved user-friendliness of operations for setting local
subdivisions in hexahedral mesh division.
c. Made it possible to specify the number of divisions in hexahedralmesh division.
d. Relaxed restrictions on the inheritance and data quantity for
input parameters in the command “Sweep shell elements.”(2) Improved and strengthened the analytical functions
a. Added a contact analysis function for the large deformation
problem in elastoplastic analysis and thermal elastoplasticanalysis. This function enables analysis of the following contact
state.

(6) Improved and enhanced post-process functions
a. Resolved the issue of small text being difficult to read in thedisplay of analytical results.
b. Improved the post-process function so that the rotated statein the CAD modeler is reflected in the display of analytical results.

Contactanalysis(7) Upgraded the installation environmenta. Reduced the number of installation steps and improved
messages displayed for suggesting measures required to resolve
problems that occur during installation.
b. Eliminated virtual drive R, using only drives P and Q while
MemsONE is executing.

b. Included process recipes for company-supplied multiprocessemulatorsc. Improved and strengthened the MEMS circuit simulator• Added a function for extracting a macro model to generateMEMS elements from results of structural analysis.
• Added the ability to adjust the number of nodes on a rigidplate.
• Enabled pull-in analysis of gap elements.
• Improved the editor function and strengthened the postprocess functions.

(8) Added a network license function
Added a function that enables multiple users, within thenumber specified in the license agreement, to use MemsONE
simultaneously on computers connected to a LAN.
Through the improvements and enhancements describedabove, version 4.0 of MemsONE is anticipated to be a more
complete tool with remarkable advances in the quality anduser-friendliness of its features. Sales and distribution ofversion 4.0 will begin in February 2011, and the MMC iscommitted to product dissemination. At the same time, will beoffering user assistance through training courses andtechnology forums, for example, and will work to attract newusers and expand our regular user base.

(3) Improved and strengthened the feature for setting
analytical conditions
a. Enhanced the functions for browsing the material database in
the conditional settings for mechanical analysis and enabled theinclusion of matrix data.
b. Added a time history table to the boundary conditions forelectric potential in piezoelectric analysis.
c. Integrated the number of output steps with the number ofcomputational steps.
