Ladies and gentlemen my name is young Kelly I

'm a

senior manager for restoration software devel

opment advances Pleasure to present

progress is we have made at ansys

Unless you're moving technologies today

Before something to talking about technical s

tuff I would like

to introduce myself very quickly

I'm a 50 something year old guy with some Gra

y

hair

We still like watching animation movies

To be honest alot more than my daughter does

Which may sound a bit childish

But whenever I watch animation movies recentl

y released I cannot

help but being amazed by natural movements of

characters

Meticulously renders textures and colors etc

In fact modern day animation movies are produ

ced by using

so many technologies common to what we use fo

r physics

modeling and simulations

Moving is 1 example of such technologies

If I may oversimplify An engineering simulati

on usually starts with

all geometric model for a product or process

Then we add load conditions under conditions

material properties etc

Which are followed by machine and connection

Were the other way around

With a discretized model an engineer carries

out physics simulations

And simulation results are reviewed and evalu

ated

If everything looks fine and acceptable the d

esign is complete

As most of us here know in real life the

story does not end with such a lock

Engineers usually need to iterate this design

cycle

One needs to go back to the geometric model t

o

make design change

Which is followed by the subsequent steps aga

in But what

if we can make changes on the data ready set

up ready for simulation

Yes that is exactly what national thing is ab

out

When moving is suitable it enables rapid desi

gn change iterations

The other word it can be very close effective

So how does mesh motor works

To understand mathematical theories behind

Let us imagine two points When we know the va

lue

of a property the point is is open called the

sampling point

And what we want to know is the value at

the other point which can be anywhere in the

domain

It is quite natural strategy to try to extrap

olate the

value from the sampling point to the other po

int

In terms of distance between them

In other words the value at a point in the

domain becomes a function of the radial dista

nce from the

sampling point It can be again expressed as t

he multiple

of a question And radial basis function

These are the radial basis functions commonly

used in the

engineering field

So far so good right

By the way why did we have many such sampling

points

Of course we can extend the same extrapolatio

n strategy to

all the sampling points

Which makes the value at the point be on line

ar

combination of the radial basis

It's population from all the points

Note that we know all the values at a simple

point

So we can compare the given values at the sam

ple

point and the computed values and evaluate th

e error

By minimizing the least square error with res

pect to the

correction

We can construct a system will be creation

Theoretically we can compute the questions by

solving the system

of equations

In practice social set of coefficients may no

t exist or

the system of equations can be either conditi

ons meaning difficult

to solve or unsolvable Two is the problem

Open linear polynomial terms or constants are

added

To the end the problem becomes solving a syst

em of

equations shown here

So how is this related to machine moving

Mission molding is a special case where the v

alues at

the sampling point are vector values instead

of scholar values

And those vectors are the moments

As a result We have to solve three sets of

system of equation independently then we know

all the coefficients

and additional terms

Once we know them we can compute smoothly ble

nded movements

for every node of a mesh

In other words two more for mash for each not

e

4th we compute the distances from the load to

other

sampling points

2nd we evaluate radial basis function with th

e distances and

Lastly summing the products of grations and r

adial basis functions

This will provide the movement of the note

By moving each note using the computed moves

we are

able to move the mesh as schematically lustra

ted here

We formed a small team of engineers advances

about one

and half years ago we developed the core tech

nologies such

as in our linear matrix solver and preconditi

oning schemes etc

I experimented various smoking controls We're

very excited to updates

the progress is we have made today

So one may ask what is special about our mach

ine

working

Goes there are several machine working produc

ts available in the

market

Another answer for the question first we offe

r much more

intuitive and easier working controls for exa

mple we call direct

mapping

Allows the user to choose measure regions and

move them

around while smoothly blending neighboring Ru

ssian regions

Often excessive movements deteriorate match q

uality

You mention can be used to fix such issues

Combination of translational and rotational m

oves in different directions can

be applied using extra attention

I

The next control is called offset multi this

control enables

user to inflate or deflate chosen reasons by

pushing and

pulling in the normal direction of the servic

es

Windows electric measure regions are cylindri

cal shape and this equivalent

to changing the radius

I Grid multi let users easily setup agreed in

cluding a

model agree this initialized by constructing

a regular grid completely

including the model

And agree that can be easily modified as the

video

in lost ways

One can change the shape of model by pulling

and

pushing edges

Spaces in both pieces of the grid

It changes the deformation of the model

I Leslie much more ping allows users to Morga

n mesh

model

To a target ship

It is important to note that this is not abou

t

simple projection

Our method compares the source mesh

And the target shapes

And move the mesh toward the target shape whi

le preserving

important geometric features

For example The shower features

Corners in this video

It is quite common that the manufactured prod

uct has a

quite different shape from his design

For example a product manufactured by diecast

ing undergoes a significant

shape change due to the thermal shrinking

In such cases This could be particularly usef

ul to match

our mesh model which is used during CA in sim

ulation

for design to the scanned data of the manufac

tured product

possibly to evaluate performance using the ac

tual ship

Another important aspect of our new technolog

y is the ability

maintaining measure quality In here has 24 he

ader bounding layers

What's worse aspect ratio is over 100 when we

twist

the machine for a stress test our new machine

moping

keeps the machine valid up to 100 degrees

Which is not possible with other compareable

methods

I

Last but not least if this is new national pi

ng

is extremely fast

The videos presented today were recorded on a

8 core

engineering laptop machine

Our unique server techniques and algorithms w

ill provide almost real

time moving experience for matches of million

s of cells on

such a small machine

It has gotten even better since we recorded t

he billions

In summary we have developed of very fast mac

hine moulding

technology that maintains good match quality

during the moving through

various controls

We are working hard to deliver the technology

to the

market

Again it was my great honor to present today

on

behalf of the engineers whose name appeared h

ere

I hope everyone has enjoyed the presentation

and would like

to thank your time and attention

Thank you
