STRAND7

STRAND7 is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand STRAND7 rather than just read about it. In short: Strand7 is a Finite Element Analysis (FEA) software product developed by the company with the same name. History The Strand computer software was first developed by a group of academics from the University of Sydney and the University of New South Wales.

Key takeaways

STRAND7 belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect STRAND7 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of STRAND7 from memory before moving on to harder problems.

Reference excerpt

Strand7 is a Finite Element Analysis (FEA) software product developed by the company with the same name.

History The Strand computer software was first developed by a group of academics from the University of Sydney and the University of New South Wales. Further to this early research work, an independent company called G+D Computing was established in 1988 to develop an FEA program that could be used commercially for industrial applications. Between 1988 and 1996 the company researched, developed and marketed a series of DOS and Unix based FEA programs, most notably its STRAND6 program. In 1996 the company commenced work on a completely new software development specifically for the Windows platform. This product was first released in 2000 and was named Strand7. In 2005 the company also changed its name to Strand7 to better reflect its primary focus.

Application Some high-profile applications of Strand7 include the optimisation of the "Water Cube" Beijing National Aquatics Center for the 2008 Beijing Olympics, the "Runner" sculpture that was placed on top of Sydney Tower during the 2000 Sydney Olympics and the Terminal 2E roof, Charles de Gaulle Airport.

Analysis Capabilities Strand7 is most commonly used for the construction and mechanical engineering sectors, but also has seen use in other areas of engineering including aeronautical, marine and mining. Strand7 includes the following solvers:

Linear static Natural frequency Buckling Nonlinear static Linear and nonlinear transient dynamic Spectral and harmonic response Linear and nonlinear steady-state heat transfer Linear and nonlinear transient heat transfer

Worked examples

Example 1 — a first encounter with STRAND7

Start with the simplest possible case. Write down what STRAND7 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to STRAND7 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about STRAND7 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of STRAND7

In research: STRAND7 appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses STRAND7 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: STRAND7 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Finite element software, so understanding it makes those chapters shorter.
In everyday life: Look for STRAND7 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is STRAND7 in simple terms?

Strand7 is a Finite Element Analysis (FEA) software product developed by the company with the same name. History The Strand computer software was first developed by a group of academics from the University of Sydney and the University of New South Wales.

Why does STRAND7 matter?

Because it connects several chemistry ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study STRAND7?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
