I would like to use the angle symbol to represent polar numbers (phasor notation for electrical engineering. In other words, I would like to enter 10<30 instead of polar(10, pi/6). Also, I would like the results displayed with the angle notation.  Is this possible in Maple. In the "other package" by PTC this is trivial. Even on a TI graphing calucator it is trivial. Someone please tell me it is possible in Maple.

For computation, Maple is great. For presentation, there is a lot to be desired. 


When doing numerical calculations or evaluations it is very useful to have float results shown in numeric notation, where the exponent is 3 * n.

Below are some simple calculations:

Is there a way to make Maple show the resultin (1) .. (3) as:

  • 333.3 106
  • 333.3 103
  • 333.3 100 or just 333.3


Recently, entered a engineering graduate program and will be taking a graduate engineering class in my retirement.  In our Into classes we reviewed engineering math through ODE. In the second class, we performed some numerical methods using MatLab with a small introduction.  My formal Math wass in the 1980s, but now have to fire it up for a Engineering Analysis using Michael Greenberg's Advanced Engineering Mathematics, 2nd which has Maple imbedded code and directions.


What would be my assignment for getting up to speed with using Maple to solve algebraic-symbol-programming problems? For instance, which tutorials in what order, or webinars? i think I once had Fortran 77 and remember zip.


Appreciate any good advice.


We've added a collection of thermal engineering applications to the Application Center. You could think of it as an e-book.

This collection has a few features that I think are pretty neat

  • The applications are collected together in a Workbook; a single file gives you access to 30 applications
  • You can navigate the contents using the Navigator or a hyperlinked table of contents
  • You can change working fluids and operating conditions, while still using accurate thermophysical data

If you don't have Maple 2016, you can view and navigate the applications (and interactive with a few) using the free Player.

The collection includes these applications.

  • Psychrometric Modeling
    • Swamp Cooler
    • Adiabatic Mixing of Air
    • Human Comfort Zone
    • Dew Point and Wet Bulb Temperature
    • Interactive Psychrometric Chart
  • Thermodynamic Cycles

    • Refrigeration Cycle Analysis 1
    • Refrigeration Cycle Analysis 2
  • Miscellaneous
    • Measurement Error in a Manometer

I have a few ideas for more themed Maple application collections. Data analysis, anyone?

Maple is a scientific software based on Computational Algebraic System (SAC) which has enabled this work entirely solve applied to Civil Engineering, Mechanical and Mecatrónica.The present problems in education, research and engineering are developed with static work sheets ie coding used innecesaria.Maple proposed models are shown below with an innovative structure; with the method of graphics algorithms and embedded components; putting aside the traditional and obsolete syntax; using dynamic worksheets as viable and optimal solutions to interpret and explain problems Ingineering.Design Advanced Analysis Tools (Applied Mathematics) Sophisticated Applications (efficient algorithms) and Multiple deployment options (different styles); this allowed generate math apps (applications engineering); can be interactive on the internet without the need to have the software installed on our computer; This way our projects can be used with a vision of sustainability around the world. Resulting in the generation of data and curves; which in turn will help you make better decisions analytical and predictive modeling in manufacturing and 3D objects; which would lead to new patterns of contrasting solutions.

Valery Ochkov and Volodymyr Voloshchuk have developed a series of thermal engineering applications in Maple 2016. The applications explore steam turbine power generation and refrigeration cycles, and use the ThermophysicalData package for fluid properties.

Their work can be found at the following locations on the Application Center.

I especially like

  • this application, which optimizes the extraction pressures of a steam turbine to maximize its efficiency,
  • and this application, which plots the state of a two-stage refrigeration cycle on a pressure-enthalpy chart.

In this course you will learn automatically using Maple course Statics applied to civil engineering especially noting the use of components properly. Let us see the use of Maple to Engineering.

Hello, I'm new to Maple and have a problem with making some electrical engineering.

I miss the unit VA (volt-ampere) which is used in AC. Maple won't recognize it and when I type it separately it changes to W (watt).

Hope someone can help me, thank!

By the way, how do you insert "Maple Code" in here?

In this paper we will demonstrate the importance of using simple to complex algorithms applied to complex systems in civil and mechanical engineering. In order to develop solutions that developers need to be involved in issues of advanced dynamic computer science. We show how is that with the Maple scientific program and through component-based algorithms can generate power then then be inserted into specific algorithms. Will form patterns with movements of rotation and revolution of their axes, in each case to model and analyze the curves thereof comprising. With these modelalos and curve analysis we can predict manufacturing costs, freight, inter alia estrcturas which they can be used with the correct use of Maplesoft.

ABSTRACT. In this paper we demonstrate how the simulation of dynamic systems engineering has been implemented with graphics software algorithms using maple and MapleSim. Today, many of our researchers the computational modeling performed by inserting a piece of code from static work; with these packages we have implemented through the automation components of kinematics and dynamics of solids simple to complex.

It is very important to note that once developed equations study; recently we can move to the simulation; to thereby start the physical construction of the system. We will use mathematical and computational methods using the embedded buttons which lie in the dynamics leaves and viewing platform cloud of Maplesoft and power MapleNet for online evaluation of specialists in the area. Finally they will see some work done; which integrate various mechanical and computational concepts implemented for companies in real time and pattern of credibility.

In this paper we will demonstrate the many differences of implementation in the modeling of mechanical systems using embedded components through Maplesoft. The mechanical systems are used for different tasks and therefore have different structure in its design; as to the nature of the used functional elements placed on them, they vary greatly. This diversity is reflected in approaches and practices in modeling.

The following cases focus on mechanical components of the units manufacturing and processing machines. We can generate graphs for analysis using different dynamic pair ametros; all in real-time considerations in its manufacturing costs from the equations of conservation of energy.
Therefore modeling with Maplesoft ensures the smooth optimum performance in mechanical systems, highlighting the sustainability criteria for other areas of engineering.

Hello, Currently when I calculate something, for example R=U/A where R is resistance, U is voltage and A is current, I get the answer in Volt/Ampere in stead of ohm. How do I change that?

Then, if the result is something like 3.124*10^-4 , how do I make maple output this in an engineering way, this would be 10^3, 10^6, 10^9 etc. to begin with?

Sorry if I formulate this wrongly, English is not my first language and I could not find an answer to this after some research.

Thank you


UPDATE and solution: for future reference:

You don't need to type out the whole unit like this:


in stead you can do this:


I got the V and A from the SI Units palette on the left hand side,


To answer my own question about the engineering notation, this can be "forced" by clicking on "Format" -> "Numeric Formating..." -> Engineering and then choosing the number of decimals. apply and set as default. After you are going to have to copy and recalculate your math as the !!! wont do it.

In this work the theme of vector analysis shown from a computational point of view; this being a very important role in the engineering component; in civil and mechanical special it is why, using the scientific software Maple develops interactive solutions for long processes through MapleCloud calculations. At present the majority of professors / researchers perform static classes open source leaves; so that our students learn and memorize commands, thus generating more time learning in the area. Loading Bookseller VectorCalculus develop topics: vector algebra, differential operators, conservative fields, etc. Maplesoft making processes provide immediate calculations long operation Embedded Components displayed in line with MapleNet integrations. Today our future engineers to design solutions and will be launched in the cloud thus being a process with global qualification in the specialty. Significantly Maple is a scientific software which allows the researcher to design their own innovations and not use themes for their manufacturers.







In this paper of presents under a totally modern sound environment dynamics; using embedded components that gives us the Cybernet Company through its product Maple 2015. Using classical techniques vector equations describe the particle, particle system and solid bodies. We note that the solutions o ered by this software motivate students civil and mechanical engineering to nd optimal answers. Integrating algorithms own programming language and solid mechanics using buttons we relate the movement of translation and rotation with reference to its center of mass.
Choosing envelopes graphical methods, functional programming and mathematical computer display modeling reached alternatives to achieve the next generation of engineers. Therefore this work show that the use of
embedded components allow us to merge the traditional and the computer; It means that all these equations using physical and propose viable criteria we perform in a dynamic sheet; which they have a number of components; then generate simulations with real objects.
