KBruch is a small program to practice calculating with fractions. 4 different exercises are offered:
* Exercise Fraction Task - solve a given fraction task. You have to enter numerator and denominator. This is the main exercise. The difficulty of this task can be influenced by the user. The user
... [More] can decide if he wants to solve tasks with addition/substraction and/or multiplication/division. Also he can set the number of fractions and the maximum size of the main denominator
* Exercise Comparison - compare the size of 2 given fractions
* Exercise Conversion - convert a given number into a fraction
* Exercise Factorization - factorize a given number into its prime factors [Less]
FFC works as a compiler for multilinear forms by generating code (C or C++) for the evaluation of a multilinear form given in mathematical notation. This new approach to form evaluation makes it possible to combine generality with efficiency; the form can be given in mathematical notation and the
... [More] generated code is as efficient as hand-optimized code.
FFC is a component of the FEniCS project, see http://www.fenicsproject.org. [Less]
The FInite element Automatic Tabulator FIAT supports generation of arbitrary order instances of the Lagrange elements on lines, triangles, and tetrahedra. It is also capable of generating arbitrary order instances of Jacobi-type quadrature rules on the same element shapes. Further, H(div) and
... [More] H(curl) conforming finite element spaces such as the families of Raviart-Thomas, Brezzi-Douglas-Marini and Nedelec are supported on triangles and tetrahedra. Upcoming versions will also support Hermite and nonconforming elements. [Less]
