+Code to localize strains and homogenize stress in a Representative Volume Element (RVE) by using Finite Element Method (FEM).
 
 # Characteristics
 
-1. Works with structured grids 2D or 3D
-2. Plastic non-linear material model for testing the memory storage and efficiency.
-3. Supports boundary condition : uniform strains (Pure Dirichlet)
-4. Runs sequentially.
-5. Own ELL matrix routines with CG iterative solver (diagonal pre-conditioner).
-6. Different kinds of micro-structures
+1. Works with 3D structured FE elements problems
+2. OpenACC acceleration support for GPUs
+3. OpenMP support for multi-core CPUs
+4. Solver: Conjugate Gradients with Diagonal Preconditioner (CGPD) 
+5. Different varieties of micro-structures and material laws
+6. Native instrumentation to measure performance
+7. C and Fortran Wrappers
 
 # Main Characteristics
 
-_micropp_ solves the FE problem on heterogeneous RVEs composed with more than one material and calculates the average properties of it. In the next figure a typical micro-structure is solved.

-`MicroPP` has been coupled with high-performance codes such as [Alya](http://bsccase02.bsc.es/alya) developed at the Barcelona Supercomputing center ([BSC](https://www.bsc.es/)) to performed **FE2** calculations. Also it was coupled with [MacroC](https://github.com/GG1991/macroc), a FE code that uses PETSc library on structured meshes. With this good performance was reach until 30720 processors on Marenostrum IV supercomputer.
