V4.0

ShearFlow Analysis

A new checker is added, in replacement or complement of Fx analysis. This checker is by default selected for non-standard zones, but available for standard loads.

Push-To-Reference

V3.2

Dynamic LOPA Visualization

For newly created models, a dynamic LOPA viewer is provided in-place of static LOPA image. This dynamic LOPA allows zomming, coloring data, mouse Hovering, etc..

A basic introduction is shown Dynamic Lopa.

Loads transfer to rail axis system

Loads are now transferred point by point, and not based on item’s angle as previously. This allows a correct load transfer when an item is localized on both canted and regular rail.

Major Library update

Some major libraries are updated to their latest release.

V3.1

Drop units specifications from lcids_acc tab

Starting from V3.1.1, legacy spreadsheets lcids_acc need to be modified. The units row (the second row in the input spreadsheet) must be dropped as shown Fig. 131. Running a legacy non-modified spreadsheet will lead to a validation error as shown Fig. 132.

lcids_acc required modifications

Warning

Breaking Change starting from V3.1.1:

This change makes previous lopa spreadsheets obsolete.

The lcids_acc tab does not expect units anymore. When running a legacy spreadsheet, one will get this error:

Main page improvements

Now, depending on selectez zones type (non-standard or standard), or if only standard zones are found in the layout, references selection are shown or not.

As shown Fig. 133, References panel (1) is shown only if non-standard analysis are available and at least one non-standard zone is selected (2).

Miscellaneaous bug fixes

  • Differential repetitions is now OK

  • Analysis does not crash anmymore when creating shear flow critical figures

  • Checkers are now selected as per selected zones

  • Fix issue occuring when no “analyze” section is present in batchfile.

V3.0

Mystran is now the unique Solver

As of floortools V3.0, the internal solver is droppped in favour of Mystran 14.01

Granularity and flexibility

in V2 version, floortools was basically running two steps:

  • binding (associate a lopa with a structure) and validation

  • run + postpro + check and report in one shot.

The V3 version in more atomic; the process can be re-triggerd starting at any of those steps.

One of the main point is it allows to change a checker option (eg. shear panel window’s width) without running the first three points (binding, run and postpro).

As of V3.0 the web interface does not make und extensive use of this granularity, except for post-analysis XLSX traces dumping and reporting:

post-analysis actions

Loading Axis definition

IFL are by default assumed to be entered in Aircraft Global Coordiantes System. User can now specify that a set of loads are submitted in the the rail coordinate system by using axis field.

item_loads::axis definition

Sections

ftoolsV3 has now an internal notion of Aircraft’s sections. This can be seen in several places like graphs.

Geometry items orientation

The implementation of item_asm::item_axis field, (not to be confused with tem_loads::axis field) allows to choose orientation of an item.

FEMAP and PATRAN groups

FEMAP neutral file (.neu) and PATRAN neutral file .ses are now available as deliverables. They provide groups for virtual beams, sections, zones and loading.

V2.3

Add Mystran as an alternative to internal solver

Mystran is available as an alternative to internal solver. Mystran is faster, much faster, than the legacy internal solver. It is also more powerful.

V2.2

Add High-Level validator for better validation errors handling

A new validator is implemented, able to catch cross-tabs errors.

Ftool can now work on non-seats only zones

A zone occupied by non-seats only items (eg. galleys and lavatory area) can now be analyzed

non-std seats only zones

Fig. 137 Non-standard Seats only zone

[Template] item_asm tab

Column seat_row_id of Sheet “item_asm” tab is now forbidden for non-seats items.

V2.1

Add Seat Track clips non standard analysis

Seat track clips (also known as goussets or clips) are now included in Non-standard analysis.

Aircraft type and fsconf

When selecting an aircraft structure to bound a lopa on, the combo box provides the Aircraft type and fsconf ID as additional informations:

V2.0

Both Standard and non-standard analysis are available.
