Field Precision finite-element software covers a broad spectrum of physics and engineering applications, including charged particle accelerators and X-ray imaging. The core underlying most of our software packages is the calculation of electric and magnetic fields over three-dimensional volumes.
In this area, our software has high accuracy and achieves the fastest speed of any available 3D package. An important feature for small laboratories, universities and consultants is that the cost is far below that competing products.
Magnetic field analysis with MagView. To use our electric and magnetic fields software effectively, researchers should have a background in electromagnetism and should be able to make informed decisions about solution strategies.
First-time users of finite-element software may feel intimidated by these requirements. In the end, readers will be able to solve real-world problems with the following programs: All finite-element programs solve fields in three-dimensions, but often systems have geometric symmetries that can be utilized to reduce the amount of work.
The term 2D applies to the following cases: Cylindrical systems with variations in r and z but no variation in? The 3D calculation would increase the complexity and run time with no payback in accuracy.
We need to clarify the meaning of static in electrostatics and magnetostatics. The implication is that the fields are constant or vary slowly in time. The criterion of slow variation is that the systems do not emit electromagnetic radiation. Examples of electrostatic applications are power lines, insulator design, paint coating, ink-jet printing and biological sorting.
Magnetostatic applications include MRI magnets, particle separation and permanent magnet devices. A following coarse will cover simulations of electromagnetic radiation e.
Numerical methods should be used when it is not possible to generate accurate results with analytic methods. Numerical solutions are necessary in the following circumstances: The system has a complex asymmetric geometry The solution volume contains many objects with different material properties Materials have complex properties e.
The initial analysis gives an understanding of the physics involved and the anticipated scales of quantities, essential information for effective numerical-solution setups. The worst case is when a user hopes that the program is an omniscient black box that will figure everything out.
No matter what software manufacturers claim, using a field program without understanding fields is at best a gamble.Problem Solving and Python Programming: Files, Modules, Packages - brief important questions and answers and Example Python Programs on Files, Modules, Packages 1.
The NLTK module is a massive tool kit, aimed at helping you with the entire Natural Language Processing (NLP) methodology. Aug 10, · How to Start Programming in Python.
Do you want to start learning how to program? Getting into computer programming can be daunting, and you may think that you need to take classes in order to learn. Remember that you can quickly write scratch programs directly in the interpreter, and testing your changes is as simple as running Views: K.
Mar 17, · Course Excerpt: Writing Functions in Python Below is an excerpt–video and transcript–from the first chapter of the Python Data Science Toolbox I course. It discusses writing functions in Python.
How to count aminoacids from a text file? My file contains sequences. After getting amino acid composition, I have to create a Bar plot. How to do these things in Bio python? I parsed the sequence file in to Biopython. I tried the following code to get amino acid composition.
Every element of BLOSUM matrix is computed by the formula. #Method 3: List comprehension: def square_even_lc(arr): return [i**2 for i in arr if i%2==0] %timeit square_even_lc(range(1,11)) Output: loops, best of 3: µs per loop RunTime: LC is ~25% faster than for-loop and ~65% faster than map function.
Getting Started with Python 1. Getting Started With Python 2. SECTION 1 Introduction to Python 2 3. What is Python? Python is a general purpose, high level and powerful dynamic programming language. Python is an Object Oriented Programming language i.e it is based on classes and objects where each object can communicate with other by exchanging messages and processing data.
