Multiphysics Product Development

Simulation of solid and structure mechanics problems. The code uses open source Eigen3 library for matrix multiplications, linear algebra and solving linear system of equations. Eigen-Documentation.

Version 0.1.3

• Switched solvers from iterative to direct solver (LU based) to maintain stability in code.

Compile and Run Code

To compile the code, invoke the call to Makefile i.e. by simply typing “make -jN” in command line.

• The -j is the jobs tag i.e. give directive to compiler for parallel build.
• N is the number of parallel jobs to run, this depends on the total threads and cores of user’s CPU.
• To Remove all object and executable files from main directory : make clean
• For more inforamation about make options, use syntax : make help

To run the code, go to directory contining mesh and JSON files then run excutable : PATH-TO-MPS-Product-Dev/RunCode

Comments from Development Team

• The code needs a total of 3 JSON input files i.e. solver , boundary and parts.

  • solver.json contains the inputs for solver, equations and material properties of the domain.
  • boundary.json file contains the boundary conditions {Dirichlet, Neumann, Initial} defined as per the problem by user.
  • parts.json contain all the subsequent parts of the whole domain {Multibody problems}. parts input must be defined for each problem even for non multibody problems.

• Read the Documentation for inputs JSON file format.
