Structural / Civil Engineering App for aiding the intuitive understanding of the behaviour of space-frames under load.

CASA Intuition allows the user to create 3D structural models and obtain both a graphical representation of the deflections and forces and also normalised numerical values for easy comparison of effects around the structure (no actual numerical results are given).

There is an emphasis on quick and precise input of high-resolution data through graphical tap-and-drag interaction, with numeric input available as an alternative. Automatic concurrent analysis ensures that up-to-date results are conveniently available after every edit. Clear graphical representations of deflections and force envelopes are interactive with slider bars which provide the reading off of numerical values at any point along the members.

Information on how to use this App can be found both in the in-built help and also on our website.

=== Technical features ===

* Continuous automatic real-time analysis in response to changes.

* Metric & imperial units.

* Integrated extensive section library:
– European: HD, HE, HL, HP, IPE, IPN, LE, LU, UAP, UPN
– American: W, HP, HSS, C
– Australian: UB, UC, WB, WC, SHS, RHS, CHS, PFC, EA, UA, TFB, UBP
– Japanese: HJ
– Russian: BFB, NFB, RSC
(Displayed property values are normalised for ease of comparison.)

* Integrated section generator for common shapes
– Open: I/H, channel, zed, angle, tee
– Hollow: Oval, Rectangular
– Solid: Oval, Rectangular
– Calculates: Calculates: Area, Inertia, Torsional constant, Elastic moduli, and mass per unit length
(Displayed property values are normalised for ease of comparison.)

* Integrated material library:
– Steel, Aluminium, Concrete, Timber, Glass

* Nodes may be restrained in a variety of ways.

* Members can be rigid or pinned at either end.

* Arbitrary combined loadings of point, couple, and trapezoidal loads.

* Multiple loadcases.

* Graphical results and numerical values include:
– Reactions.
– Deflections.
– Bending moments.
– Shear forces.
– Bending stress.
(Numerical values are normalised for ease of comparison.)

* Numerical values at any position along members.
– Points of interest automatically determined.

=== User Interface features ===

* Universal App – for iPhone, iPod, and iPad.

* Four simple interactive screens:
– Geometry: for creating and editing nodes, members, supports, and section properties.
– Loading: for creating and editing loads.
– Results: for reading numerical values and viewing graphical deflections and force envelopes.
– Utilities: unit system choice; on-line help; load/save file; reset.

* Easy and accurate graphical drag-and-tap controls:
– High precision positioning of nodes and loads by dragging with a finger.
– Drag loads along to set position.
– Drag loads and envelopes to specify magnitudes.
– Drag marker along deflected shape or force envelope to read off value.

* Numeric entry available if preferred:
– Double-tap on an input variable to enter its value numerically instead of graphically.
– A built-in calculator is provided to add flexibility to numeric input.

* Section library presented as a straightforward selection:
– Tap on button in geometry window to open library.
– Tap on category (e.g. British UB).
– Tap on section size.
– Diagram and dimensions will appear; tap on a Use button to pick major or minor axis.

* Custom property generator accessible in the library:
– In library, choose custom category.
– Diagram and dimensions will appear; double-tap on a dimension to edit it.
– Properties will automatically recalculate when dimensions are changed.
– Choose a material by tapping on the blue button.
– Tap on the Use buttons to pick either major or minor axis.
