IGES (*.igs *.ige *.iges)

STL (*.stl *.sta *.stb)

Step (*.stp *.step)

Creo up to version 3.0 (*.prt* *.asm* *.g *.xpr *.xas *.neu)

CATIA V5 (*.CATPart *.CATProduct)

CATIA V4 (*.model *.exp *.dlv *.dlv3 *.session)

Optional auto-backup of projects while saving:

No results

Network drives

supported


Translations and rotations of a component can be reset:

No need to remove the geometry first

Confirmation needed


Particles (single points) can be imported from CSV files:


Remote

A default remote profile can be preset:

The availability of cores is checked

on the remote server during the start of

the simulation.


Rigid dies with heat conduction can be used as trimming

dies:

Trimming (before/only)

Trimming while forming


The progress display was improved:

Individual process

Multiblow (hammer and screw presses)

Stage control

Incorrect status information, e.g. if terminated on press force, was

corrected


Improved calculation of automatic heat transfer coefficient:

Now material properties of both

contacting partners are considered.


Material database:

The material group „tool steel“ is limited to materials for deformable dies (elastic). Materials suited for metal forming simulations were moved to “General steel”

New materials for sheet metal forming at room temperature: BH210

BH280

BH300

BH340

DDQ

DP500

DP600

DP800

DQSK

HCT600XD

HCT780C

HS440WGA

HSLA350

HSS590

IF

MS1400

TRIP590

TRIP600

TRIP780


Material data can be assigned to dies with type “rigid die without heat

conduction”:

If assigned, the assigned material properties are used

If nothing is assigned, material properties from tool steel H-13 are used

(similar to “rigid dies with heat conduction”)


Result value contact status:

Contact to symmetries added

Uniform for FE and FV solvers

Result tree restructured:


New result value error element:

Indicates “inside-out” elements

Use element filter to show only

the inside-out elements and their

direct neighbors

Belongs to “standard” result group


Usability of comparison view in THS plots was improved:

Imported data can be activated & deactivated from selection.


For simulations using a counter blow hammer and the FV

solver all energies (gross/net available/delivered) are always

shown for the entire press. It is not anymore necessary to

summarize the individual tool energies.

Sub-stages

Backstroke:

May now be larger than 100%, input may be given as distance, e.g. in mm

Can be used in combination with terminate on tool forces

Can be used if die positioned at BDC and automatic positioning of tool used

Meshing

Improved self-contact:

Hexmesh

C folds ok

V folds instable as sharp folds

will create geometries impossible

to be hex-meshed particularly if

sharp edges are detected

Tetmesh will be

improved further in upcoming

versions

Example of large fold meshed with Hexmesh

Meshing

Remeshing can be controlled:

Based on criteria (default)

Only forced

Never (simulation will stop debugging)

Adaptive mesh refinement, type “contact”

Symmetries do not cause refinement

anymore.

Tools will be selectable by user

[development ongoing].

Symmetry

Hot forging (FV solver)

Multiple (segmented) dies can be

used also for screw and hammer

presses.

Time-ramp-up is supported also for screw presses.

Effectively reduces the force peak at initial tool contact.

Hot forging (FV solver)

New termination criterion on tool forces added:

Stops the simulation when given tool force is exceeded

Should be used together with solver step control „time

ramp up“

Mechanical joining

New process types self-piercing riveting, punch riveting,

blind riveting and tensile test

Optimized initial and advanced settings

Automatic measuring (self-piercing riveting and clinching)

Mechanical joining

New additional termination criteria:

Self-piercing riveting

Clinching

Mechanical joining

If the sub-stage “release workpiece from stationary dies” is used, all

sheets and adhesive layers are excluded from the release as a default

setting.

Mechanical joining

Modified strategy if inside-out elements occur

(may occur if glue is used and/or mesh separation is required):

Solver cutbacks first

Forced remeshing

Elements will be deactivated (if activated in the forming control)

Stability improvement

Pressure welding

New result value: Automatically calculated electrical contact

coefficient

New contact type for resistance spot welding:

temperature drops from melting to solidus temperature

contact glued

Added support for segment-to-segment contact for

application module pressure welding

Electrical material properties (phase-dependent) can be

imported from JMatPro

Optimization

Any object attached to the process tree can be exchanged

in a serial examination and optimization

Optimization

Use “create all optimization cases” to create and start the

simulation of (many) variants:

Optimization

Serial examinations

Can be carried out running several simulations simultaneously (if

licenses available).

A failed simulation will not stop the serial examination or

optimization run anymore.

For selected process types the components can be positioned

automatically.

Not only for optimization

Auto-positioning for initial positioning

for selected processes:

Friction spot welding

Spot welding

Self-piercing riveting

Notes

Positioning is done by translation along

global z-axis.

Lowest component is used as reference

(position is not changed).

Component roles for self-piercing

riveting must be defined. Components

without roles (e.g. fixings) cannot

be positioned.

Rivet is not positioned but punch

is positioned on rivet's top.

Not only for optimization

The initial meshing (in addition to remeshing) settings are

kept if the geometry is exchanged.

Process chain simulations / interfaces

Import results from casting simulation with Procast

Geometry

Temperature

Shrinkage porosity

Stress

Export only one geometry

and one step (increment)

per *.unv file

3D geometries only


Import results from casting simulation with Procast

Import UNV files with „Geometry Mesh from file“

Unit of result values is read from UNV file and transferred to

Simufact.forming automatically

After importing the geometry, mesh + results are available in the

object catalog

Shrinkage porosity is converted into

relative density


Export interface of simulated press forces to Brankamp

process monitoring systems:

Facilitate tool setup & increase die life

Use simulated results as a reference for production

Note: requires special license from Simufact and Brankamp


In case of a GUI crash memory dumps are written to allow

easier debugging & customer support:

MemoryDump files saved in folder

%APPDATA%\simufact\MemoryDumps of the current user

No customer data (geometries, material data, etc.) are stored

Only activated if the setup was carried out with admin privileges

Top bugfixes

Blocked read-only access by the solver to CUR, HIST and RES files was fixed.

Incorrect stress transformation in dieload simulations with rotating dies fixed.

Several reasons for occasional GUI crashes were resolved.

Symmetry planes are now correctly transported to the next stage by the stage

control if “automatic workpiece symmetry” is used.

Not working output divisions based on stroke during backward stroke were fixed.

“Jumping” forces in remeshing time steps have been fixed.

Incorrectly shown validity in the license manager was corrected.

In total almost 400 bugs were fixed.

Top bugfixes

Resolved meshing issues

SurfaceMesher: Various issues like occasional memory leak and very long meshing

times or meshing failures have been resolved.

HexMesher: An error was resolved that under rare conditions produced a mesh with

holes on the surface.

Sheetmesher: Incorrect mesh produced if geometry to be meshed had small holes or

narrow notches was resolved.

Setup

Supported operating systems:

Windows 7 (64 bit), Windows 8 (64 bit)

Linux (64 bit): FormingGP GUI and solvers only (mainly tested on

RHEL 6.3 / CentOS 6.3)

Graphic card requirements:

OpenGL 2.1 or newer

Min. 1GB RAM on graphics card

Use newest driver available

Note:

If all colors are displayed grey when using the Windows remote

desktop or a Teamviewer session, the graphics card drivers need to be

updated on both computers.

Setup

Simufact.forming GP (as well as Project and

Quickpost) are installed with a separate setup

using a separate path and their own solver.

Setup

Settings have been made independent from installed version and can

be transferred to new versions when the GUI is opened for the first time:

The need to register with a password for the MPI service was removed:
