KOWLOON, Hong Kong, Jul 8, 2019 – Precise Simulation Ltd. is pleased to announce that its FEATool Multiphysics version 1.10 has now been released and is available as a dedicated MATLAB Add-On and self-contained Toolbox (available with one-click directly from the MATLAB Add-Ons Toolbar). The following new features are available with FEATool Multiphysics 1.10.

Automated Multiphysics Tutorials




The FEATool Multiphysics GUI has been overhauled and improved with built-in and automated tutorials to easier get started with multiphysics modeling. By selecting any of the examples from the File > Model Examples And Tutorials… menu starts and automated replay of the steps required to set up and run the model. At present, about 35 tutorial models are available for different physics types and more will be made available in the future.

In conjunction with the automated tutorials a new finite element script model file format is also introduced. This format allows the entire GUI modeling session and workflow to be saved and subsequently identically replayed, which is ideal for teaching and tutorials. In addition to the MATLAB script (.m) file format, finite element script (.fes) is also a simple text file format that can be inspected, edited, and put under version control. Altogether user can now save and export models in binary (.fea), MATLAB m-script, and finite element GUI script formats for complete control over simulation model data and reproducibility

Eigenvalue Solver

In addition to the stationary, non-linear, and time-dependent built-in solvers, FEATool 1.10 also introduces a new eigenvalue solver which can be accessed and used from the GUI as well as the MATLAB API as the solveeig function. The eigenvalue solver is for example used in the resonance frequencies of a roomvibrations of a drum membranecantilever beam, and vibrations of a hollow cylinder tutorial models.

Edge Constraints

In addition to Dirichlet and Neumann boundary conditions and point constraints, full 3D edge constraints are also now available. This new feature is for example used in the stress analysis of a thick plate NAFEMS benchmark example.

New Postprocessing Functionality

In addition to sharing model and simulation results via the social web, the FEATool GUI now features dedicated one-click buttons to export simulation data as Plotly and ParaView Glance web plots. Follow this link for a demo

FEATool ParaView Glance and Plotly Web Plot Examples

Simulation data can now also be manually exported to regular CSVParaView (.vtk/.vtp), and General Mesh Viewer GMV formats using the Export option in the Post menu or the corresponding import/export CLI functions.




Further improvement to postprocessing functionality includes a deformation plot option whereby one can prescribe a field to deform and distort the resulting plot, which for example can be used to see how a structure is deformed by a load. Moreover, two new command line functions postextrude and postrevolve can be used to extrude and revolve 2D and axisymmetric simulation data to create corresponding 3D visualizations.

Additional New Features

  1. Support for multiple STL sections and files during STL CAD file import.
  2. Functionality to make geometry object copies (available with the Transform geometry object tool in Geometry mode or on the command line with the copy_geometry_objectMATLAB function).
  3. Improved and more accurate evaluation of general expressions in grid and mesh points.
  4. Dedicated GitHub repository for external grid generators with pre-built static binaries for 64-bit Windows, Linux, and Mac OSX systems. (Cannot be distributed along with FEATool due to incompatible software licenses, but are automatically downloaded when requested if an internet connection is available.)

About FEATool Multiphysics

The FEATool Multiphysics software suite is developed by Precise Simulation Ltd. Established in 2013, after close to two decades of developing both commercial and academic simulation FEM and CFD codes, Precise Simulation was founded as a reaction to the frustration of having to choose between closed, complex, and difficult to use commercial software tools, or open source but (even more) difficult to use academic tools, with nothing in between.

The idea and vision of FEATool is then to provide a truly easy to use software simulation tool that everyone can use right away (with ultimate goal not to require users to consult any documentation at all). In particular, starting with FEniCS and FeatFlow, FEATool uniquely aims to provide easy interfaces to excellent academic and open source simulation codes and software which otherwise would take a significant time to understand, learn to use, and run. For more information, visit http://www.featool.com.
