  • Save applications if the license server connection is lost before exiting your app.
  • New and more robust tetrahedral meshing algorithm.
  • Partition selected domains prior to meshing in order to create domain shapes and sizes more applicable for the mesh operation.
  • Import mesh parts and material data that uses mesh parts and integrate with the geometry sequence.
  • Save memory and computing power by caching parts of a solution when running studies where you only need part of a solution for visualization and results.
  • New annotation feature in 2D and 3D plots.

Application Builder

  • Over 50 new and updated example apps published to the Application Library showcasing many different features and functionality from the Form and Method editors.
  • New Editor Tools window to go from model and application content directly to tailor-made form objects.
  • Update graphics and plot while solving.

COMSOL Server™

  • Application load times have been significantly shortened while administrators can choose to preload apps when launching COMSOL Server™.
  • Select an app to launch as soon as a user logs into COMSOL Server™ without going through the Application Library.
  • Reconnect to applications that are currently running from any location and any browser or COMSOL Client.
  • Create desktop shortcuts to launch applications.


  • Present impedance, admittance, and reflection data in Smith plots.
  • Use external nonlinear magnetic material models from user-defined dynamic libraries in the definition and simulation of magnetic fields.
  • Automatic scaling of skin depth for lossy electric and magnetic media through physics-controlled meshing.
  • Release of rays from edges and points.


  • Incorporate third-party libraries or functions of material models, written in C code, which define the stress-strain relation or return an inelastic strain contribution for nonlinear material simulations.
  • Improved formulation for small strain plasticity with geometric nonlinearity.
  • Represent frequency-domain transfer functions, responses, sensitivity curves, insertion, and transmission loss in acoustics applications through octave band plots.
  • Added documentation and flowchart to help in selecting the appropriate fatigue model for different scenarios.


  • Simulate three-phase flow and the interaction of three immiscible fluids through using the phase field method.
  • Introduction of the algebraic yPlus and L-VEL turbulent models for mixing applications for less resource-intensive computations.
  • Model compressible flows and account for the Bernoulli effect in pipe flow applications.
  • New convective heat transfer coefficient correlation for natural convection around vertical cylinders.
