Precise Simulation Releases FEATool 1.7 Multi-Simulation

With the release of FEATool 1.7 Precise Simulation is introducing the modeling and simulation tool concept Multi-Simulation. The goal of Multi-Simulation is to allow for switching between built-in and external solvers and simulation tools. Beginning with FEATool 1.7, Multi-Simulation supports the FEniCS multiphysics and the FeatFlow CFD solvers, and the postprocessing and visualization tool Plotly. This functionality is available with easy-to-use one-click buttons directly in the FEATool GUI, as well as with Matlab and Octave m-file scripting.

The following five new PDE physics modes have been implemented and added for modeling and simulation of porous media flow, electromagnetics and one-dimensional stress-strain beam theory: Brinkman Equations; Darcy’s Law; Electrostatics; Euler-Bernoulli Beam and Magnetostatics.

The new physics modes are available to use with the FEATool GUI and on the command line for relevant space dimensions.

In addition to the new physics modes, the following physics modes have also extended to support axisymmetric cylindrical coordinate systems (pseudo 3D): Axisymmetric Stress-Strain; Conductive Media DC; Convection and Diffusion; Heat Transfer; Navier-Stokes Equations and Poisson Equation.

Support for activating/de-activating equations and dependent variables in different subdomains is now also possible. By using the new Active toggle button in the Subdomain Settings dialog box of each physics mode the equations and dependent variables can be turned on and off for each distinct subdomain. Using this feature also activates internal boundaries, which become available to assign boundary conditions to.

With the Multi-Simulation concept the FEniCS C++ and Python general FEM solution toolkit has also been interfaced with FEATool. The FEATool GUI now features an integrated one-click button and corresponding Matlab/Octave CLI functions to export and convert multiphysics grids and models to FEniCS format, and optionally use FEniCS to solve the problem (if installed and available).

Plotly is a javascript visualization and plotting library that now also is fully integrated with FEATool and can be used to visualize FEM simulation results and data. Plotly plots are stand-alone html web pages that can be inspected, rotated, zoomed and exported as image and svg files with the following benefits: fully self-contained and interactive web graphics pages; high performance plots with further export functionality and share with coworkers and colleagues through cloud and web services.
