2. What is simulation?
 The imitation of the operation of a real-world process or system
over time…
o Most widely used tool (along LP) for decision making
o Usually on a computer with appropriatesoftware
o An analysis (descriptive) tool – can answer whatif questions
o A synthesis (prescriptive) tool – if complemented by other tools
 Applied to complex systems that are impossible to solve
mathematically
 A Simulation of a system is the operation of a model, which is a
representation of that system.
 The model is amenable to manipulation which would be
impossible, too expensive, or too impractical to perform on the
system which it portrays.
 The operation of the model can be studied, and , from this,
properties concerning the behavior of the actual system can be
inferred
Textile Simulation
 Textile is proposing the textile pattern and color by utilizing the
computer simulation system to get the quick decision-making of
our customers without making a prototypes of textile fabric.

3.  The computer simulation system we own can create the complete
textile image by input the data of weft-warp yarns and weaving
patterns.
“ModSimTex” Project
 The ModSimTex project is a European Commission Community
Research 7th Framework Programmed, Priority 4 NMP Project.
 The objective of the Project is to develop a system which will
reduce dramatically the cost to develop new technical textile
products by reducing the time, energy and raw material waste
during the production machinery setup process.
 Its total budget is 4.5M€ and it will take 3 years and a half to
complete.
 The Project Consortium is composed by 3 Universities, 2 research
centers and 7 companies from 6 different Member States.
Descriptionof the Project

4. “ModSimTex” Project
 The textile industry faces important challenges regarding the production of
new advanced textile products. Itis not possibleto define the
characteristics and parameters of a given textile structuredue to the
difficulty of measuring them. his situation makes very difficult to configure
the machines involved in the production of such textiles; the typical
practices consists in manufacturing samples and through trial and error
adjustthe processing operations until the desired characteristics are
achieved in the final product.
 With this procedureit’s very expensive to match the designer’s idea with
the final product. The production setup takes a long amountof time and
efforts and increases the cost of the final product. This is especially critical
when a company is trying to develop new technical textiles.
 The vast majority of the existing systems capableto simulate textile
products arelimited to the visualrepresentation, without any kind of
mechanical or physicalevaluation of the properties of the textile structures.

5.  This virtualconstruction systemwill allow the prediction of the
multifunctional textile performancebefore the actual textile is
manufactured allowing the settings of the production machines to be either
an input or an output of the computation thus reducing dramatically the
effort and cost to producesmall batches or develop a new advanced
technological textile.
Advantages of simulation
 When mathematical analysis methods are not available, simulation may
be the only investigation tool
 When mathematical analysis methods are available, but are so complex
that simulation may providea simpler solution
 Allows comparisons of alternative designs or alternative operating
policies
 Allows time compression or expansion
CAD-CAM for Textile Products
 A wide variety of design in fabrics is based on the combination of yarns with
different colors or printing designs. To be successfulin this task nowadays is
directly related with computer design. This subjectdeals with different
programs depending on the process required to design, it will be studied
both, the one for weaving technology (to combine yarns and structures)
and the one for digital printing.
 Finally, designs created by the student/developer will be used in a program
to simulate different environments in 3D such as a living room(armchair,
curtains, carpet, etc.).

Yarn-Level Simulation of Woven Cloth
 The large-scale mechanical behavior of woven cloth is determined by the
mechanical properties of the yarns, theweave pattern, and frictional
contact between yarns.
 Using standard simulation methods for elastic rod models and yarn-yarn
contact handling, the simulation of woven garments at realistic yarn
densities is deemed intractable. This paper introduces an efficient solution
for simulating
woven cloth at the yarn level.
 Woven cloth is formed by interlacing yarns, typically two sets of orthogonal
yarns called warp and weft. Interlaced yarns undergo friction forces at yarn-
yarn contacts, and this friction holds together the woven fabric.
 Large-scalemechanics of woven cloth are dictated by the fine-scale
behavior of yarns, their mechanical properties, arrangement, and
contact interactions.
