The Ansoft support offices can be found by accessing http://www.ansoft.com/contact.cfm Alternately log on to the ANSYS Customer Portal to download software, find knowledge resources, examples, and best practices. http://www.ansys.com/customerportal Please provide the following information when you contact us: - Your name and affiliation - Version number of Maxwell - The type of hardware and operating system you are using - A description of what happened and what you were doing when the problem occurred as well as the exact wording of any messages that appeared on the screen New Features in Maxwell 15.0 ============================ Temperature dependent nonlinear permanent magnets can be modeled in Maxwell2D and Maxwell3D. [Solution file formats have changed for all the 3D solvers, some additional solution files have been added for 2D magnetostatic, eddy and transient solutions.] Also note that in order to support temperature dependent nonlinear magnets, it is now the intrinsic BH curve that is passed to the solver (regardless of which type of BH curve was used to input the data). In order for the solver to do a good curve fit through the data points it is important that there are sufficient points on the 'flat' part of the curve leading up to Br. You can also add additional points in the 1st quadrant. The 3D Electric Transient solver now supports maximum time step that can be a function. RMxprt now supports generator operation of 3-Phase induction motors. RMxprt now supports closed rotor slots for single-phase induction motors Improvements to the surface force mapping when coupling to Workbench Mechanical. Isotropic magnetization modeling in Maxwell2D and Maxwell3D: the magnetization direction is determined by the solution of a source design modeling the magnetization and used in a target design for application. Set all 3 components of the Unit Vector for magnetic coercivity to Zero for the material so that Maxwell knows to use computed direction. 3D eddy current now includes core loss computation for materials with Kh, Kc and Ke set. In the 3D eddy current solution setup dialog, under the solver tab, the user can now ask the solver to use higher order shape functions for face elements for better accuracy in the eddy current region. [See DE26967 below.] On 64-bit versions of Windows, the Maxwell interface now runs as a 64-bit executable. This allows postprocessing of larger models. There are now separate installations for the 32-bit and 64-bit versions of Maxwell for Windows. [The 3D solvers and the meshmakers already had 64-bit versions in prior releases.] The 2D solver in Maxwell is now a 64-bit executable (in the 64-bit version). In Maxwell2D, Maxwell3D and RMxprt there is now a 'SheetScan' capability (found under Datasets) that allows you to extract XY data from graphic images. In Maxwell2D there is now support for non-linear anisotropic and lamination material properties. In both Maxwell2D and Maxwell3D magnetostatic solutions there is now an option to import permeability from external user data. In the solution setup dialog's Solver tab, select "From Link" for permeability and click on "Setup Link..." Then look under the "Advance" tab on the Setup Link dialog. The RMxprt machine type 'Generic Rotating Machine' now has an option to use an internal permanent magnet (IPM) rotor. RMxprt does not do an analytical solution when using this rotor type, but can generate Maxwell2D or Maxwell3D designs. The RMxprt machine type 'Generic Rotating Machine' now has an option to create machines with Axial-Flux structure. It can also generate Maxwell3D designs from Axial-Flux motors. Improvements in Coupling with ANSYS WorkBench: - Coupling with Fluent solvers through WorkBench - More efficient transient-transient coupling between Maxwell and Mechanical - Stress feedback with Mechanical (2D is released as a Beta feature) - Geometry and material assignment transfer from Ansoft to ANSYS system - Multiple geometry sources (links) into Ansoft system - Optimetrics/DSO/animation with CAD integration A new large scale DSO wrapper executable "desktopjob" has been added to the installation. This is an alternative method for solving very large scale distributed parametric sweeps using a method that minimizes network traffic and scales better for extremely large clusters. It does not pass solutions back to the original project but generates output files based on reports defined before the project is solved. Controls for "User Defined Solutions" have been added to the "Results" menus. These allow an advanced user to define calculations using IronPython scripts, the resulting outputs become available in the reporter and in Optimetrics like other solution quantities. Major Known Defects in Maxwell 15.0 =================================== DE26967 - In Maxwell3D Eddy Current solutions, when using higher order shape functions, the field solutions are correct, but the impedance matrix parameter calculations are not correct. DE26053 - In Maxwell3D Electrostatic solutions, the QSurf calculation in the postprocessor has the wrong sign.
