New in MASTA 10

SMT are pleased to announce that the much awaited and next major release of its world-leading software, MASTA, is now available for all users and evaluators.

This latest release builds on the strengths and successes of previous versions and includes several advanced enhancements. For full details see the release notes (full release notes can be accessed via SMT Portal). Key features are highlighted below:

The next generation in commercial grade CAE design, analysis and optimisation for mechanical transmissions is now available.

Below summarizes the major updates in the latest release of MASTA, for further details get in touch


  • MASTA API to automate customer processes
  • SMT Store for example code
  • Custom results in the MASTA interface
  • Supports Python, MATLAB and .NET languages


  • ‘Unit Harmonic Force (FRF)’, ‘Unit Harmonic Moment (FRF)’ and ‘Advanced System Deflection Current Load Case Set Up’ excitation options added for gear sets.
  • Specify gear mesh excitations at orders other than the tooth passing frequency

Flexible Spline Coupling

  • Addition of Major Diameter Fit option
  • Contacts now include tilt stiffness
  • Specify a different helix angle on left and right flanks of spline teeth.
  • Determine whether a spline will slip, given a specified coefficient of friction and tangential stiffness.

Gear Teeth Meshing

  • Create FE meshes of gear teeth in MASTA and append them to imported full FEs or MASTA-created shaft FEs.

Save/Load External FEs in Multiple Files

  • Externally saved FE files (*.smtfe) are now split into (*.smtfem) files containing the mesh information, and (*.smtfev) files containing the expansion vectors.

FE Mass and Stiffness

  • Can specify an expected number of rigid body modes for an FE model.
  • MASTA will check for all-zero rows and columns of the stiffness matrix and alert the user if they are present.


  • Performance improvements when including microgeometry.

Electric Machine Data Import

  • JMAG interface.
  • Data is now specified/edited in imported FE mode and stored on a FE model.
  • Visualise nodal forces.
  • Example with Radial Flux motor with skewed rotor added to Examples Menu.
  • Example with Axial Flux motor added to Examples Menu.

Parametric Study Tool

  • Save and load results from runs.

Cylindrical Gear Mesh Power Loss According to ISO/TR 14179-2

  • Users can now choose ISO/TR 14179-2 to be used in cylindrical gear mesh efficiency calculation.

Create Additional Condensation nodes for a Group of FE Nodes or Faces

  • Users can now create condensation nodes connected to a group of selected element faces or nodes when they have the full FE mesh in MASTA for use as accelerometers or component connections
