PDLSM-FEM solver is an open-source parallel implementation of coupled peridynamics least squares minimization and finite element method (PDLSM-FEM) in 2D and 3D by MPI technique. This solver is written in a C++ environment on cross platforms. It includes implicit static, explicit dynamic, and implicit dynamic solvers for structure analysis under displacement or traction loading.
-
Pre-process- It requires a mesh data file with the specified format. Users may use commercial finite element codes such as ANSYS, ABAQUS to generate the mesh data file. -
Solver- PDLSM-FEM includes implicit and explicit solvers. For implicit solvers, it stores the large sparse matrix in a compressed sparse row (CSR) format and solves the large linear systems of equations by the Parallel Direct Sparse Solver (PDSS) of Intel Math Kernel Library. -
Post-process- It stores the results in VTK format, which can be visualized directly by Paraview.
See the manual file for further details.
