Lightweight Cell Library

Lightweight Cell Library is a collection of cell types and cell functionality that is designed be used scientific visualization libraries of VTK-m, and VTK.

You can find out more about the design of Lightweight Cell Library in DESIGN.md.

Contributing

There are many ways to contribute to LCL:

• Submit new or add to discussions of a feature requests or bugs on the LCL Issue Tracker.

• Submit a Pull Request

  • See CONTRIBUTING.md for detailed instructions on how to create a Pull Request.
  • See the LCL Coding Conventions that must be followed for contributed code.

Compiler Requirements

• C++11 Compiler. Lightweight Cell Library has been confirmed to work with the following
  • GCC 5.4+
  • Clang 3.3+
  • XCode 5.0+
  • MSVC 2015+

Example

Below is a simple example of using Lightweight Cell Library to get derivatives and parametric coordinates for different cell types:

#incude <lcl/lcl.h>

std::array<float, 3> pcoords;
auto status = lcl::parametricCenter(lcl::Hexahedron{}, pcoords);

std::vector<std::array<float, 3>> points = { ... };
std::vector<std::array<double, 4>> field = { ... };
std::array<double, 4> derivs[3];
status = lcl::derivative(lcl::Hexahedron{},
                          lcl::makeFieldAccessorNestedSOAConst(points, 3),
                          lcl::makeFieldAccessorNestedSOAConst(field, 4),
                          pcoords,
                          derivs[0],
                          derivs[1],
                          derivs[2]);
