Build
The build system uses SCons. In order to construct the library you should hit:
scons
And to speedup the process you can do:
scons -j 6
In order to clean the build
scons -c
In order to compile in debug
scons build_type=debug
Indeed the default was
scons build_type=release
In order to make the compilation more verbose
scons verbose=true
You can customize a few compilation variables:
- CXX changes the compiler
- CXXFLAGS adds flags to the compilation process
For example:
- scons CXX=icpc compiles with the intel C++ compiler
- CXXFLAGS=-mavx2 scons adds the -mavx2 flag (which enables some Intel instructions) to the compilation process
If the CXX variable is defined in your environment, scons will take it as a default compiler.
Coding
C++
All classes and functions in Tamaas live in the \tamaas\ namespace. Here is an example main:
using namespace tamaas; int main (int argc, char * argv[]) { // Initializing tamaas initialize(); // Surface parameters const UInt grid_size = 1024; const UInt k0 = 4, k1 = 4, k2 = 32; const Real hurst = 0.8; const Real rms = 0.1; // Surface generator SurfaceGeneratorFilterFFT sg; sg.getGridSize() = grid_size; sg.getQ0() = k0; sg.getQ1() = k1; sg.getQ2() = k2; sg.getRMS() = rms; sg.getHurst() = hurst; sg.getRandomSeed() = 56; sg.Init(); Surface<Real> & surface = sg.buildSurface(); // BEM object BemPolonski bem(surface); bem.setEffectiveModulus(1.); // Solving equilibrium Real load = 0.01; bem.computeEquilibrium(1e-12, load); Surface<Real> & tractions = bem.getTractions(); Surface<Real> & displacements = bem.getDisplacements(); // Cleaning up tamaas finalize(); }
Python
Tamaas also has a python interface. Here is an example:
import numpy as np import tamaas as tm tm.initialize() # Surface generation SG = tm.SurfaceGeneratorFilterFFT() SG.getGridSize().assign(512) SG.getHurst().assign(0.8) SG.getRMS().assign(1.); SG.getQ0().assign(4); SG.getQ1().assign(4); SG.getQ2().assign(32); SG.getRandomSeed().assign(156); SG.Init() surface = SG.buildSurface() bem = tm.BemPolonski(surface) bem.setEffectiveModulus(1.) load = 0.01 bem.computeEquilibrium(1e-12, load) tractions = bem.getTractions() displacements = bem.getDisplacements() tm.finalize()
Paralellism
Tamaas features shared-memory paralellism with OpenMP. The number of threads can be controlled via the OMP_NUM_THREADS environment variable or the omp_set_num_thread() function in the OpenMP API.
