FFTMAD is a software tool for computational homogenization based on the Fast Fourier Transform. The software aims to obtain the response of any heterogeneous material, as composites, polycrystals or celular materials, by simulating the behavior of a Representative Volume Element of the microstructure. The code is remarkable more efficient in CPU time and memory allocation than Finite Element homogenization.
FFTMAD includes preprocessing tools for microstructure generation of composites and polycrystals. Any constitutive equation can be used for the behavior of the materials by either a material subroutine Abaqus-UMAT or a pre-programmed model as elasticity, hyperelasticity, elasto-plasticity and crystal plasticity. FFTMAD solver is parallelized in GPUs or threads and includes different schemes for linear and non-linear problems. Postprocessing is done using python tools and Paraview.
FFTMAD is programmed as a Python project including NumPy, SciPy, PyEVTK, PyFFTW, and PyCuda libraries as well as home made subroutines in Fortran. A simulation in FFTMAD is performed by simple scripts defining the RVE, materials, load histories and postprocessing options.
The three types of licenses available for FFTMAD under GPL and their respective costs include the following:
