There are some striking differences
between MEMSolver and other existing MEMS design tools
available in the industry. Some of them are listed below.
MEMS Analytical Software
It is not another Finite Element
Modeling (FEM) software. Existing software tools for
MEMS design based on numerical and finite element
simulation require its users to have extensive knowledge
and theoretical background of the physics applied to
these micro scale devices. FEM is useful in some cases
to understand localized stresses like that due to sharp
corners. But in most situations what someone is looking
at are the final results like deflection, maximum
stress, output etc. An FEM tool is not required for
these and can be solved using analytical models.
Device design and process simulation
capabilities
MEMSolver is a unique tool that
combines MEMS device design and process simulation. MEMS
is an interdisciplinary field and so should be MEMS
development tools. MEMSolver has system level models
for micro electro-mechanical-thermal modeling for device
design along with
models for some of the most widely used semiconductor
processes used in MEMS fabrication. No need to buy
separate software for these jobs. MEMSolver has 1D, 2D
and 3D plotting and animation capabilities.
Price advantage
A MEMS developer often has to buy
very expensive software, hire engineers who has expertise in
the use of this software and impart necessary training
before this software could be used. These softwares are
often beyond the reach of academic institutions and
researchers. Separate software
tools will be required for design and process
simulation. Days and weeks of programming and research
are needed before results can be generated. MEMSolver is
a solution to all those problems.
Supports complete product
development flow
Using MEMSolver, a project engineer
or researcher who may not have much knowledge of the
physics applied to MEMS devices could develop a MEMS
device from concept to processing. Select a suitable
beam design and run a stress analysis, carry over that
beam design to study its dynamic characteristics under
vibration and damping. Use any of the actuation or
sensing schemes like electrostatic, thermal,
piezoresistive etc to develop it into a sensor or
actuator. Then develop a microfabrication process that
goes along with the device and with the available
fabrication equipment. Calculate final yield.
Ease of Modeling
MEMSolver uses GUI based modeling.
Insert the values for the structural dimension of the
device in a text box and generate results at the click
of a button. No new programming languages to learn. Save
and recreate the entire model with a single line
of command.
Accuracy of results
When it comes to theoretical
accuracy of a model, analytical models score high. In
the case of FEM, eventhough the underlying theory is the
same, the final result would depend on the modeling
skills of the person, the generated mesh and how well
the loads and boundary conditions are applied. The
results that MEMSolver provides are theoretically
accurate for the given conditions, and what every FE
model attempts is to get a result close to the
analytical solution. Every model is provided with an
example which allows the user to make a comparison with
any other model they might have.
Minimal run time and result
generation
Compared to finite element models,
MEMSolver generates results in a very short time. No
large result files are created. The entire model and
results can be saved as a small text file. Final results
can be plotted in intuitive graphs with data export
facility.
Ideal instructional tool
A university researcher or student
will find MEMSolver a very useful tool in their learning
process. It is a tool developed for professional MEMS
developers made available to them at an affordable
price. An academician will find the graphs and plots very
intuitive and helps them in understanding their project
work and beyond. The help files gives them a good
theoretical background of every design.
Free evaluation
MEMSolver is a downloadable
software with free evaluation, a rarity among commercial
MEMS software tools. This "try before you buy" approach
is the ultimate guarantee that the software will perform
to your satisfaction.
The comprehensive set of
features, user-friendliness and price advantage
definitely sets
MEMSolver apart from all the other MEMS software tools in the
market. It allows any MEMS developer, what ever his
level of competence or expertise, to take advantage of
all it capabilities and efficiently deliver a reliable
product in no time and with unmatched ease. |
