PFC Documentation, Release 5.0

When PFC is executed for the ﬁrst time, three dialogs are likely to appear.

The ﬁrst is the Copy Application Data dialog. The user is strongly encouraged to either accept the proposed location

in this dialog or supply a new one. Once complete, this dialog will not appear on future startups. See the topic Copy

Application Data for complete information.

The second dialog is the Update Alert dialog. This dialog appears when an update of the program is available from

the Itasca web site. Unless the user happens to have installed the program very close to the release date of PFC 5.0,

this dialog will most likely appear on ﬁrst starting the program. See Update Alert Dialog for more information.

The third dialog is the Startup Options dialog. When starting the program the ﬁrst time, the most sensible option here

is either “Create New Project...” or “Cancel”. See the topic Startup Options Dialog for more information.

PFC for the First Time

1.6 PFC Folder Layout

In the program installer, the default destination for the program is:

This folder and the folders it contains hold the program executables and dlls, all examples, and the program documen-

tation. Any references in this Help ﬁle to ﬁles, folders or other program-related material that should be accessible to

the user will assume the default directory structure is in use.

The executable ﬁles for PFC are “pfc2d500 gui.exe” (PFC2D) and “pfc3d500 gui.exe” (PFC3D). PFC is compiled

with the Intel C++ Compiler 12.1. In addition to the executable code, a set of dynamic linked libraries (DLLs) is

provided.

PFC Folder Layout

1.7 Startup Options

The Startup Options dialog appears when PFC is ﬁrst run. The dialog provides a quick way of choosing what to do

vis--vis the project system when ﬁrst starting. The dialog can set PFC to do the same thing every time the program

starts if the checkbox “Do not show this window again” is checked. This causes the program to always perform the

action that is used to dismiss the dialog in this instance which in turn means the Startup dialog will be suppressed

on future startups. If the user wishes to change this behavior either to select a different startup option or to set the

program back to showing the dialog on each start this may be done by accessing the Startup section of the Options

dialog.

1.8 System Requirements

To install and operate PFC, your computer must meet the following minimum requirements:

Processor - A processor with a minimum clock speed of 2 GHz is recommended. The speed of calculation for a PFC

model is directly related to the processor’s speed. Therefore, the selection of a high-speed processor is a key factor for

improving computational efﬁciency. A chip that supports a 64-bit operating system is also required.

Hard Drive - At least 150 MB of hard disk space must be available to install PFC. Save ﬁles are roughly proportional

to the size of your model in RAM. A model consisting of 500,000 balls with 3,500,000 contacts results in a save

PFC Documentation, Release 5.0

ﬁle of approximately 3 GB. A model consisting of 1,500,000 balls with 9,000,000 contacts results in a save ﬁle of

approximately 8 GB.

RAM - The minimum amount of RAM required to load PFC is 100 MB. The memory allocated for a PFC model is

adjusted dynamically to take up the required RAM for a model at the time the model is created. The RAM required is

similar to the amount of hard drive space required.

Generally, the combined RAM needed by PFC and its model storage should leave 0.5 to 1 GB available to Windows.

Otherwise, Windows starts swapping into virtual RAM (on disk), which causes a dramatic performance loss in PFC.

The more applications there are running simultaneously, the smaller the PFC model should be.

Display - For best performance, a screen resolution of at least 1024 x 768 pixels and a 16-bit (at least) color palette

are recommended.

Operating System - PFC is available as a 64-bit native Windows application. Currently, Itasca ofﬁcially supports the

Windows operating systems in 64 bit: XP, Vista, 7, and 8.

Output Device - By default, plots from PFC are sent directly to the Windows native printer. Plots can also be directed

to bitmap formats (PNG or BMP), among other export options.

USB Port - 1 USB port is required for a USB local license. A TCP/IP connection to a server (with a USB port) is

required for a USB network license.

Operation on PC Networks - A network version of PFC is available. The network key allows a single hardware dongle

to be placed at a central location. Individual users can then run PFC from any computer on the network. Network

keys require a special licensing arrangement and installation. Contact Itasca for details.

1.9 Next Steps

New Users

We encourage new users to look at the Tutorials. This extensive set of projects will give you the chance to dive in and

explore the program immediately. Each tutorial includes a project/data ﬁle(s) so all material related to the tutorial may

be loaded now. The tutorials are designed to quickly introduce the new user to a wide array of key concepts in using

PFC. Each tutorial provides a thorough, guided discussion of each step, each command, and each program feature

used. Though this Help ﬁle is exhaustive and the new user may want to do further reading before working with the

program, if you want a hands-on exposure the tutorials are a superior starting point.

Experienced Users

Where to start for experienced users is a bit trickier. PFC 5.0 is a dramatic upgrade from its predecessor, and experi-

enced users are strongly encouraged to spend a bit of time ﬁnding out just how dramatic. The following topics provide

one possible pathway which would quickly expose experienced users to the core advances in this version.

• Experienced User Primer

• New Features of PFC 5.0

• The New UI For Experienced Users

Upon review of these topics the experienced user may want to work through the example problems contained in the

Examples and Veriﬁcation Problems section, as these will give a hands-on illustration of the many changes detailed in

the above three topics.

Getting Started Next Steps

1.9. Next Steps 11

PFC Documentation, Release 5.0

The Version Number, Explained

The version number of PFC follows a simple numbering system that identiﬁes the level of updates in the program.

There are three numerical identiﬁers in the version number that is,

where:

is an integer starting with 1 that identiﬁes a major release of the code;

is an integer that is incremented whenever a modiﬁcation is made that requires a major change to the code structure

for a supplemental upgrade release of PFC; and

is an integer that is incremented when minor modiﬁcations are ofﬁcially released as an update to the current version.

Subversion Numbers

The exact version of the program that you are using is determined by the subversion number, which is a digit that

appears after a dot (.) after the third digit () described above. Lower subversion numbers represent earlier versions

than higher subversion numbers. Sub-version numbers are used to identify minor changes to PFC that have been

made since the ofﬁcial version was released. The program can automatically detect whether there is a new subversion

available (see the topic Update Alert dialog for more information).

Caution: PFC with a sub-version number greater than that of the ofﬁcially released version should be used with

caution, because not all features have been fully tested.

Get Version

2.3 Get PFC Updates

Use the menu sequence . This will open the Revision History for PFC in a new broswer window. The revisions as

shown are sorted by date, from newest (top) to oldest (bottom). Compare the latest subversion number (ﬁrst column)

to the one shown in the program’s title bar. A greater subversion number in the revision history indicates a later version

than the one you are operating is available. Above the table containing the revision history a link provides access to

the download page that can be used to access the program update, if you wish to get it.

Program updates are distributed as installation packages. To update PFC, simply run the downloaded .msi ﬁle and

follow the prompts to complete installation of the update.

The program’s revision history is also accessible through the action of the Update Alert dialog. See the topic on that

dialog for more information.

Get Update

2.4 Get the PFC Revision History

Itasca commits to correcting any code errors or problems as its highest priority, and to delivering those corrections to

PFC on a ﬁx-by-ﬁx basis. That way users do not have to wait for patches or intermediate releases to obtain necessary

corrections to problems they encounter. Because of this, users are encouraged to familiarize themselves with the

revision history of the program. Each update to the code is assigned a subversion number, is dated, and is annotated

on a revision history that is kept on Itasca’s web site. This history is available at all times from within the program

(assuming the user has a working internet connection). To access it, use the menu sequence . This will load the revision

history into a new browser window.
