FloTHERM New Functionality, fth10.1 1 June 2014

Detailed Change Description This document provides an overview of the changes available in FloTHERM fth10.1.

Combined Project Manager and Drawing Board Application Windows

Ref. Title Description

1.1 Undockable Drawing

Board graphics area

The Drawing Board area may be optionally undocked from (and re-

docked with) the Project Manager node tree via the [Window] menu or

toolbar icon.

The undocked Drawing Board can then be moved over to a second

monitor display.

1.2 Stored Number of

Drawing Board

Views

The last number of Drawing Board views used in a FloTHERM session

is now saved and restored when restarting FloTHERM.

2 FloTHERM New Functionality, fth10.1 June 2014


1.3 Project Manager IDF

Preferences

The default and filtering settings used when using the Project Manager

IDF import feature are available in the User Preferences dialog. These

are shown only if the ‘Configure IDF’ box is checked.

Note that these settings only apply to Project Manager IDF import (via

the right-click assembly import). IDF import through FloEDA Bridge

is handled seperately.



1.4 Display of Axis on

Selected Objects

Drawing Board display of the local coordinate system axis on selected

objects can be controlled via the ‘Drawing Board’ tab in the [Edit/User

Preferences…] dialog



1.5 Display of the

Solution Domain

Drawing Board display of the Solution domain can be controlled via

the ‘Drawing Board’ tab in the [Edit/User Preferences…] dialog



1.6 Display of

Workplane Outline

Drawing Board display of the Workplane can be controlled via the

‘Drawing Board’ tab in the [Edit/User Preferences…] dialog.

This setting will show or hide the workplane outline, but the display of

grid cells is independent of this setting.



1.7 De-keypointed

Indication Tolerance

Whether an object is indicated as having one or more faces de-

keypointed in the Summary Columns can now be controlled via a %

tolerance value in the ‘Summary’ tab in the [Edit/User Preferences…]

dialog

Objects that resize less than this amount, in the direction that has a de-

keypointed face, will NOT be indicated as being de-keypointed



1.8 Configurable display

of Integrated

Summary Columns

What summary columns are displayed next to the Project Manager

node tree can be controlled via the ‘Summary’ tab in the [Edit/User

Preferences…] dialog



1.9 Mirror Geometry When one or more objects are selected, a Mirror function enables those

objects to be mirrored about the workplane of the active viewport.

Either by the Mirror icon or [Geometry/Mirror] menu entry.

1.10 Workplane Location The exact location of the workplane can now be defined in the

Workplane toolbar.



1.11 Rotate View [Viewer\Rotate View] command added to enable full control of

viewing angle. The view can be rotated about either the model axes or

the current viewing angle.



1.12 Extended Measure

Tool

The measure tool has been extended to allow:

• Any number of objects to be selected

• Edge selections, in addition to vertex selection.

1.13 Find Command Find command extended to have two tabs:

1. Quick Criteria. This is the simpler Find command previously

available in v9.3 and earlier.

2. Extended Criteria. This is the query based Find command

introduced in FloTHERM v10.0.



1.14 Property Sheet

Sizing

All property sheets will be sized automatically upon object or attribute

selection to ensure the entire contents of all property sheet tabs are

visible.

1.15 Right-Click object

access to Property

Sheet Tabs

The Project Manager node tree supports right-click access to a list of

property sheet tabs. When a tab name is selected, the property sheet

active tab will update accordingly.

1.16 Multiple apply for

Compact

Components

Multiple apply is now supported for more Compact Component data:

• ‘General Model’ Power Definition

• ‘2-Resistor’ Model Thermal Resistances



1.17 Recently Used

Projects List in

different solution

directories

Selecting a project from the ‘Recently Opened List’ under the Project

menu that resides in a different solution directory will automatically

change to that solution directory and load the model.



1.18 Auxiliary Variables Flow Angle and Total Pressure auxiliary variables can be calculated via

the ‘Model Setup’ tab.

Once calculated they can be displayed in the Visual Editor

1.19 Zoom-In Model

Creation

Zoom-In Models can be created via a right-click option for valid

Volume Region objects.



1.20 Apply All to Initial

Variables

In the Solver Control tab, the Initial Variables section now has two

settings:

• All Initial Values:

o Used to make a setting that applies to all variables

• Initial Value

o Used to change the setting for the active variable.

If the Initial Value setting every variable is not identical, then the All

Initial Variables field will display ‘Set Individually’.



1.21 Initial Sub-Domains Initial Sub-Domains can be defined. Initial values of solved variables

can be set in these volumes whereupon they will be used as a starting

condition for a steady state or transient solution.

Initial values set in sub-domains will overwrite the intial conditions

defined elsewhere via ‘Initial Variables’ in the ‘Solver Control’ tab


Automation


2.1 FloXML support of

PowerMap

SmartParts

The FloXML file format can now reference PowerMap .csv files, of the

type adhering to the format exported from HyperLynxPI.

A new spreadsheet example is provided that illustrates the use of this

new feature to create an extremely detailed model of a BGA substrate

from stack up information and black and white images of the metallic

distribution.


FloEDA Bridge


3.1 Network Assembly

component support

Network Assembly components originating from FloTHERM Pack or

T3Ster Master (.xCTM file format) can be added to the library and used

in the construction of FloEDA Bridge models.

3.2 Monitor points for

all Simple

components

Monitor points are now created for all Simple components during

transfer. Previously, unpowered Simple components did not have a

Monitor Point.

FloMCAD Bridge


4.1 Stand alone

operation

FloMCAD Bridge can be operated in standalone mode as in previous

versions


Transient Analysis


5.1 Transient Attribute

Multiplier Hysteresis

Support

Hysteresis for transient attributes can optionally be included by

defining an ‘Increasing Curve’ and a ‘Decreasing Curve’.

Solver


6.1 Solar calculation

performance

improvements

The solar calculation has been made more efficient, and now offers

support for multiple cores. The time required to complete the solar

calculation is now much improved with the average improvement for a

range of models shown below.



6.2 Abort Solver During any portion of the solution, an Abort Solver Action command is

available in the Solve menu. This will stop the calculation quickly, but

without saving results. As all solver progress is lost with this

command, a confirmation dialog will appear before the solver is

aborted.

The [Solve\Revert] command can be used after an aborted solve to

restore the previous set of results if required for either solver

initialization or post-processing.



6.3 Linux Batch Solve For Linux systems, a new ‘Batch Solve’ script is available that supports

the full range of FloTHERM batch solve options for PDML and

FloXML files. These include:

• Initialize from a specified solution

• Write CSV Tables data after a solution

• Create a .pack file after solution

Data Center Applications


7.1 Capture Index

Calculations

Cold Aisle Capture Index and Hot Aisle Capture Index can be

calculated by defining ‘Cold Aisle Groups’ and ‘Hot Aisle Groups’ for

Rack, Cooler, Perforated Plate, Fixed, and Recirculation Device

SmartParts.

The Capture Index calculation is activated in the Model Set Up tab:

Objects that can participate in the Capture Index calculation will have

an additional tab used to define Cold Aisle Groups and Hot Aisle

Groups.


Application Examples


8.1 New Application

Examples and

FloXML Examples

There are two new Application Examples installed with FloTHERM

v10.1:

Detailed FCBGA. A high resolution approach to modeling BGA

substrates using the Powermap SmartPart.

The substrate is modeled with two objects:

1 - The 'Dielectric' cuboid

2 - The 'Detailed_Substrate' PowerMap SmartPart.

Both of these objects were automatically created by the 'Detailed-

Substrate.xlsm' spreadsheet provided in

examples\FloXML\Spreadsheets installation folder. This spreadsheet

accepts layer stackup data and bitmap images that represent the copper

distribution on each of the substrate layers.

Package on Package Hysteresis. A package on package device with

temperature controlled power dissipation on the bottom die.

The entirety of the package geometry was created with the 'Package-on-

Package' spreadsheet installed in \examples\FloXML\Spreadsheets\

The temperature control is defined with the new transient hysteresis

attribute

.

8.2 FloSCRIPT

Examples

The following new files are available in the

flotherm/examples/FloSCRIPT directory:

• Linear-relaxation.xml

• Reset_solver_controls.xml

Running the Linear-Relaxation FloSCRIPT file will set all linear

relaxation values to 0.999 so that they can be modified (Linear

Relaxation values of 1 are not displayed in v10.1).

Running the ‘Reset_solver_controls’ FloSCRIPT file will set all false

time step and termination residual values back to defaults.
