  Modelling & Simulation Resources on
  Internet for everyone!

The hidden secrets of success in
advanced countries:
The famous phrase, "why reinventing THE WHEEL?" is
the accepted rule for not repeating the things in everyday life, education and
research. The industry invests huge sums in the development of simulation and
modelling tools to preserve the successful and authentic  experiments and
methods which have been proven after hard work and exercising the full scale
expertise and efforts. The data generated from these simulators and models match
the possible predicted results from a real experiment, however, subjected to the
assumptions and skills. These assumptions and skills depend on the choice of  
picking the correct variables which come from the original models, basic
fundamentals and also from the regular feedbacks from hit and trials.

All the world class academic and research
institutions encourage the use of some sort of simulation development tools and
aids to obtain cost-effective and efficient solutions. The subject matter is not
limited to the field of Engineering, Science, Technology, Architecture,
Business, Commerce and Social sciences but it covers almost every walk of life.
This is simply to save cost, efforts and time.

This section is produced for the academic
researchers to learn about the resources which are available on the internet
(several are free to download subject to their terms and conditions, for instant
demo/evaluation/ time limited/student versions, etc) which will enhance the
personal skills and as well knowledge about the subject methods. Those students
and scholars looking forward to proceed abroad for this postgraduate research
degree must do some background work to match the resonance. Otherwise they will
let themselves down to learn that they have to learn these tools from the
scratch and will waste their valuable time. Unfortunately our academic research
standards in Sindh, Pakistan and south east Asian countries is not so high as
compared to developed countries. Nonetheless, the personal efforts will help to
improve and learn these simulation tools quickly and effectively before leaving
abroad. here we attempt to provide a list of identified and used simulation
development software, numerical analytical packages describing their
applications. Please feel free to browse the links provided. The long list is
still incomplete and every effort will be made to make this useful. If you
identify any other useful software that is available on Internet, please do let
us know about it so that our researcher could benefit from these hidden sources
of success.


No claim notice!
we are not affiliated in any way with any one of the companies who produce the
simulation tools listed below. We do not personally provide support or endorse
any particular simulation tool. If you have an enquiry about customer support or
downloads of academic or evaluation version, please contact the developers. This
is a review of simulation software that does not aim to be complete and have
been gathered from Internet resources of public domains. Some of the links may
be changed or broken. If you want me to add a link to a particular tool, please
send an
email
to sindh2uk.

Types of Simulation and
modelling tools: It is not possible to categorise simulation tools
accurately (i.e. based on applications, numerical models or interface etc)
therefore if you are not sure about the types or
group where the particular simulation software may belong, it is advised to
ignore the categories and give a
few minutes of reading the contents of this page to find out yourself about
useful package.
