Parameters for the Solver and for the Equations are independently set through the Property editor Data tab of their respective objects in the tree view.Click on the SolverElmer object in the model tree view.One or several equations can be used at once with Elmer by simply adding the equation object under the SolverElmer object, thus performing multi-physics analyses:.Thus when using in FreeCAD the "Flow Equation", in reality Elmer uses the "Flow Solver" to find a solution to the Navier-Stokes equation. Disambiguation: The term Equation is used in FreeCAD to describe the different physical mechanisms, the term Solver is used in all Elmer documents.To perform the analysis of a particular physical behavior, an Equation must be used (Flow, Heat, Electrostatics.).Click Write to write the case files in the directory selected previously.Select the path to write the analysis in by clicking.Double-click on the SolverElmer object to prepare an analysis runĪbove: Dialog box to run an Elmer analysis.

Edit the parameters for the solver in the Property editor Data tab of the SolverElmer object in the model tree view.

Note: A successful analysis will require at least a Model (2D or 3D), a Material ( Fluid or Solid), a Mesh, Equations and Boundary conditionsĪbove: Example of a tree view once a Solver for Elmer is activated.

Create a FEM Solver for Elmer, by pressing the icon.

Create an Analysis container by pressing the icon.

Link the correct path for both ElmerGrid and ElmerSolverĪbove: Elmer preferences dialog menu showing fields to locate important Elmer binaries on Windows OS.

In FreeCAD go to Edit → Preferences → FEM → Elmer.

Download and install the version best suited to your Operating System ( Windows 64 bits or Linux).

Go to the CSC binaries resources for Elmer: binaries OR CSC binaries.

There are standalone programs for both of these applications but their installation and usage are beyond the scope of the FreeCAD integration.

ElmerSolver is handling the computation.

ElmerGrid is the interface handling meshes.

It can also be used for mechanical FEA through the Elasticity equation or any combination of the aforementioned equations.Įlmer requires two components to be interfaced with FreeCAD: Since FreeCAD already has an extensive integration of Calculix and Z88 as solvers for mechanical and thermo-mechanical analysis, Elmer will be preferred for Computational Fluid Dynamics (CFD), Heat, Electrostatics, Magnetostatics and Electrical Forces.

These are described by partial differential equations which Elmer solves by the Finite Element Method (FEM).Ĭreating the SolverElmer object in the Analysis container in FreeCAD, gives access to the Elmer Equations for simple or multiphysical analysis. After it's open source publication in 2005, the use and development of Elmer has become international.Įlmer includes physical models of fluid dynamics, structural mechanics, electromagnetics, heat transfer and acoustics, for example. Elmer development was started 1995 in collaboration with Finnish Universities, research institutes and industry.
