Agros2D

Features

• Coupled Fields - With coupled field feature you can blend two or more physical fields in one problem. Weak or hard coupling options are available.
• Nonlinear Problems - Simulation and analysis of nonlinear problems are available. Agros2D now implements both Newton’s and Pickard’s methods.
• Automatic space and time adaptivity - One of the main strengths of the Hermes library is an automatic space adaptivity algorithm. With Agros2D is also possible use adaptive time stepping for transient phenomena analysis. It can significantly improve solution speed without decreasing accuracy.
• Curvilinear Elements - Curvilinear elements is an effective feature for meshing curved geometries and leads to faster and more accurate calculations.
• Quadrilateral Meshing - Quadrilateral meshing can be very useful for some types of problem geometry such as compressible and incompressible flow.
• Particle Tracing—Powerful environment for computing the trajectory of charged particles in electromagnetic field, including the drag force or their reflection on the boundaries.
