ANSYS® Multiphysics™ - 9123 Product Features

In recent years there has been an increase in the number of industries/applications needing tosolve coupled physics problems. The Multi-field solver provides an easy-to-use framework to solve coupled field problems in many new markets and applications where previously solutions have not existed. The Multi-field solver is a general purpose, automated iterative coupled physicssolver applicable across all physics available in the ANSYS Multiphysics solution.The Multi-field solver is an evolution of ANSYS, Inc.’s successful fluid structure interaction (FSI) solver.

Materials, Boundary Conditions & Effects 3-D & 2-D planar and axisymmetric geometry

Key Features of the Multi-field Solver

Geometric nonlinearity: large strain and deflection, stress stiffening and spin softening Material nonlinearity: plasticity, hyperelasticity, viscoplasticity, viscoelasticity, creep, swelling

Each physics is treated as a field with an independent model and mesh

Contact, cracking, crushing Permeable and non-permeable domains

Dissimilar mesh allowed for each field Any number of physics fields allowed

Current and voltage excitation

Surface and volumetric loads transfer across physics fields

Stranded coils and massive conductors

Iterative (load vector) coupling is between fields and each field may have different:? Analysis types (transient, static or harmonic) ? Solvers and analysis options? Mesh descretization

Biot-Savart coils Capacitive and inductive effects Velocity effects, eddy and displacement currents

Automated morphing of non-structural elements

Lossy dielectrics

Material and geometric nonlinearity

Inductance and capacitance matrix calculations

Independent results files for each physics “field” Coupling with ANSYS

for FSI applications: Multi-field solution is distributed between more than one product (e.g., between Multiphysics and CFX)An important feature of the Multi-field solver is the dissimilar mesh interface allowedbetween each physics field. Independent users can build and set up their physics analysis field instead of having to rely on a “super-physicist” to handle all aspects of the multiphysics analysis. The dissimilar mesh interface allows more efficient meshing of physics fields resulting in more compact finite element models with faster solution times.
