Gmsh define mash along a fault

#Gmsh define mash along a fault software#
#Gmsh define mash along a fault software#
Since 1999, when Intel has launched its last single-core Pentium IV processor, software development has changed drastically. The novelty of our work lies in the fact that this work focused on the implementation of Finite Element Application (FEA) using object-oriented programming for a shared memory architecture using OpenMP without considering conventional techniques of application speedup and specialized data structures like CSR, etc. Two linear solvers Jacobi and CG are used which were consuming 95% of total solver time. Using 16 threads, the solver has attained a speedup of 5.21 for mesh having 2099201 unknowns and Poisson’s equation. Finally, this work has shown the contribution of time for each stage and the amount of speedup achieved for them. These structures are used in every stage and have never been converted into more conventional matrix structures like CSR, etc. The data structures used in this work are also C++ objects implemented using STL containers, like sparse matrix used is constructed as two-layer nested binary trees where each internal tree represents a sparse row in a global matrix. All the stages are implemented in C++ while each stage parallel regions are implemented using OpenMP. This work has focused on the study of multiple parallel implementations for each stage of the FEM solver. The FEM solver is divided into five major sections these are a collection of mesh data, creating an object for each finite element, application of boundary conditions, assembly of a linear system of equations, and lastly a solver to calculate the solution for the system of linear equations. FEM solver is designed for shared memory architectures using an object-oriented paradigm.

Paraview plugins

#Paraview plugins serial
#Paraview plugins code
In order to limit its memory consumption, this light version of Gmsh only embarks the internal data reader and the visualization procedure described above and customized for this particular application. In order to be able to use this plugin, one requires to compile a light version of Gmsh compiled as an external library as well as compiling ParaView itself with the plugin enabled. Note that this plugin is not provided in the binary release of ParaView.
#Paraview plugins code
The resulting new ParaView plugin named “GmshReader” is now provided with the official ParaView source code (version 5.7.0 and above). Note that contrary to Gmsh, VTK supports exclusively Lagrange polynomials and ParaView provides uniform h-refinement to visualize these polynomials. Although it has not been tested yet within this work, this new feature opens up additional promising perspectives for the visualization of high-order meshes and solutions. Recently, the support for arbitrary-order Lagrange polynomials has also been introduced in ParaView. Consequently, memory requirement can be significantly reduced for the selective h-refinement procedure compared to uniform h-refinement. In the second case, recursive h-refinements is applied to the parent elements and their child elements until this error is locally minimized. The recursive h-refinement of the initial mesh which generates the visualization grid can be either uniform (every edge of the parent element is split in the same way) or selective, based on a local visualization error. Afterwards, traditional visualization of the solution occurs through a straightforward piecewise linear interpolation on the Then, the high-order polynomial solution is interpolated on the new nodes of the refined visualization grid. First, a recursive h-refinement of high-order elements based on classical automatic mesh refinement (AMR) is applied and defines a refined linear visualization grid. The visualization capabilities of Gmsh rely on a two-step strategy further described in. This allows to encode any polynomial basis using the same framework. Moreover, a major asset of the native file format of Gmsh consists in the use of an explicit description of the polynomial basis functions within the file, instead of an imposed convention. Historically, few open source tools provide high-order meshing and visualization capabilities. 1 – Illustration of the usage of the GmshReader plugin in ParaView. This coupling enables parallel visualization of massive high-order solution in parallel, in client-server mode.įig. This plugin combines respectively ParaView’s scalability in parallel and Gmsh’s ability to apply h-refinement of the initial mesh followed by the interpolation of any arbitrary high-order polynomial solutions on the resulting visualization grid. In this context, a new ParaView plugin which integrates Gmsh as an external library has been implemented for off-line post-processing and visualization of high-order solutions saved under the Gmsh format, see Figure 1. Only very recently, arbitrary-order Lagrange polynomials have been introduced in VTK and their support in ParaView for both high-order meshes and solutions is gaining traction, which confirms the growing interest and need for such features. However, ParaView relies on the Visualization Toolkit (VTK) whose data models have historically mainly supported linear elements. On the other hand, ParaView is an efficient open source parallel visualization tool which has been used successfully for post hoc visualization of large scale, unstructured data sets up to several billions of dof.

However, Gmsh is in essence a serial tool and is therefore limited to a relatively low number of dof and level of h-refinements. The high-order solution is then interpolated at the new mesh nodes in order to provide an optimal visualization grid. This method relies on recursive h-refinements of the initial mesh, coupled to a projection error estimation. The open source mesh and visualization tool Gmsh provides a general method for the post-processing of high-order finite element fields. However, the lack of visualization tools able to handle a large number of degrees of freedom (dof) has been a major bottleneck for the analysis of high-order finite element solutions generated by massively parallel simulations. Recently high-order finite element methods initially introduced in the research community such as discontinuous Galerkin (DG) and flux reconstruction (FR) have gained considerable attention in industry, thanks to their high-accuracy on unstructured meshes, their efficiency and scalability.
