The previously available T-junction option now also supports Y-junctions. For distributed computing, the solvers have been optimized by the introduction of a very efficient sparse matrix reordering algorithm for direct solvers. The Fourier spectra of the computed numerical solution are compared to an analytical solution.

Mesh Selection Tools for Imported Mesh Additional tools are available for mesh selections used to subdivide an imported mesh. Two new study types for FSI are available: Both high-cycle and low-cycle fatigue methods are available, based on stress and strain, respectively.

For the Multi-Turn Coil Domain feature, a new set of wire gauge options are now available: You can now use the function mphinputmatrix to add a linear system matrix to a model. Plasma Display Panel A new model of a plasma display panel is based on the new finite volume discretization.

By default this option is not selected and all edges and vertices are kept.

COMSOL a Release Highlights

This makes it easier to work with particle tracing in cases where automatic remeshing is used. This option is available in the Advanced Properties section and is available for certain boundary conditions.

An oil rig structure immersed in seawater is protected by 52 sacrificial aluminum anodes.

The negative electric potential is applied to the inner conductor and the exterior conductor is grounded. This tutorial from the Nonlinear Structural Materials Module analyzes inflation of a Spherical Rubber Balloon for four different hyperelastic material models: The Interpolation Curve feature can now read curve coordinates from file on the Sectionwise data format in addition to the spreadsheet data format.

Here, a convex lens shape is defined via a known deformation of a rectangular domain. For example, the meshing algorithm now finds and refines the mesh at reentrant corners automatically, and creating boundary-layer meshes has been enhanced with new techniques for handling sharp corners.

Several automatic meshing tools for CFD assignments debut in Version 4. Pseudo-time stepping is a method used for robust convergence towards a steady-state solution for fluid flow. New 2D Formulations and Volume Currents New in-plane formulations for the in-plane 2D and axisymmetric 2D Electromagnetic Wave formulations includes an out-of-plane wavenumber.

Among the applications that will benefit by taking advantage of the ECAD Import Module are determining the performance of RF components under thermal or mechanical load and analyses of power electronics devices, solder creep, and PCB vibration. Export or import in violation of applicable export control laws is prohibited.

The default geometric multigrid GMG solver is now automatically adjusted based on the number of mesh elements. Fast Parallel Computing Version 4.

A new corrosion protection tutorial shows primary current distribution of a corrosion protection system of an oil platform using sacrificial aluminum anodes. You can also specify the curves as vectors of x, y, and z coordinates. Adding a heat source to a domain is useful when modeling photoacoustics and acoustic heat exchangers. New boundary conditions are available for Diffuse and General Reflection. Before deploying the anodes, the Corrosion Module is used to optimize their positions for the best possible corrosion protection.

For porous electrodes in the Lithium-Ion Battery user interface, a new liion. The model shows how stress stiffening and the combined effect from stress stiffening and spin softening affects the fundamental eigenfrequency.

The recently introduced Consol Sweep feature is engineered for compute-intensive jobs such as parametric studies and frequency sweeps. Additional multigrid levels are automatically added for large models.

  1. I do not understand something

  2. I am sorry, that has interfered... At me a similar situation. Let's discuss. Write here or in PM.

  3. Wonderfully!
