SIMULATION In Textile Products

WHAT IS SIMULATION? The imitation of the operation of a real-world

process or system over time… Most widely used tool (along LP) for decision

making Usually on a computer with appropriate software An analysis (descriptive) tool – can answer what if

questions A synthesis (prescriptive) tool – if complemented by

other tools Applied to complex systems that are

impossible to solve mathematically This course focuses on one form of simulation

modelling – discrete-event simulation modelling.

What is SimulationA 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

SYSTEM A set of interacting components or

entities operating together to achieve a common goal or objective.

Examples: A manufacturing system with its machine

centers, inventories, conveyor belts, production schedule, items produced.

A telecommunication system with its messages, communication network servers.

A theme park with rides, workers, …REAL WORLD SYSTEMS OF INTEREST ARE HIGHLY COMPLEX!!!

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 provide a simpler solution

• Allows comparisons of alternative designs or alternative operating policies

• Allows time compression or expansion

Designing Marvelous Designer Workflow

to get the idea how clothing look like when creating clothes in Marvelous Designer, the moreaccurate to real world patterns and designs you achieve, more successful your modeling will be.Therefore I did quite a bit of research on game called battle field 4, Iraq military uniform and howeach piece of clothing is constructed.

A Virtual Garment Design and Simulation System Garment design consists of defining the cloth model

andthe garment construction process, in turn of the construction of garment patterns and the definition of the seamingpoints between each panel.

To simulate the garment, the system must be integratednumerically. The positions of the particles making up thecloth are calculated over time considering the forces actingon the cloth.

Yarn-Level Simulation of Woven Cloth

The large-scale mechanical behavior of woven cloth is determined by the mechanical properties of the yarns, the weave 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 simulatingwoven 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-scale mechanics of woven cloth are dictated by the fine-scalebehavior of yarns, their mechanical properties, arrangement, andcontact interactions.

Sewing with the Garment Design System

sewing Simulation with Try On

The process chain for virtual try-on and final visualization consists of several steps. First, the automatic prepositioning, providing a good initial simulation state for the cloth-patterns with according seam information. Second, the physicalsimulation calculating the drape of the garment, where measured material data are integrated.

there is the sewing information that describes how the cloth patterns must be sewn together. Of course this information is also required, if we want to dress a virtual human with virtual garments. In a virtual try-on context, one approach is to build the virtual cloth patternswith the geometry information from the CAD systems, to sew them together virtually with the appropriate sewing information and to simulatethe real try-on process

Working with 3Ds Max.

To Create a good quality scene or image using 3Ds max there’s some requirement that must exist in the scene in order to produce a good product.

The object. Materials. Lights. Cameras. Animations.

Objects. The objects that can be represented in the

scene can be predefined primitives and models or user designed models.
