ADBenchSolids

This is a benchmark test for various Automatic Differentiation (AD) tools for deriving constitutive models in solid mechanics.

The AD tools used in this benchmark suit are:

• ADOL-C
• Tapenade
• Enzyme (C & Rust)

in addition to the hand-coded implementation of the Neo-Hookean Hyper-elasticity model in current configuration.

Download and Install

Enzyme-AD

Enzyme-AD can be cloned from GitHub.

$ git clone https://github.com/EnzymeAD/Enzyme

Follow the Enzyme documentation to build Enzyme.

ADOL-C

ADOL-C can be cloned from GitHub.

$ git clone https://github.com/coin-or/ADOL-C

Follow the ADOL-C instructions to build ADOL-C.

Building

The environment variables ENZYME_LIB, ADOLC_LIB, and ADOLC_INCLUDE must be set to build the benchmark. Assuming you have cloned benchmark-ad4solids, export these environment variables:

$ export ENZYME_LIB=[path to Enzyme] ADOLC_LIB=[path to ADOL-C lib directory] ADOLC_LIB=[path to ADOL-C include directory]

Build with:

$ make OPT="-Ofast -march=native"

Run

Create a csv file that contains n number of data (quadrature) points with:

$ python3 random-data.py n

and, run the tests with:

$ ./build/elasticity-exec
