This course provides an introduction to conducting thermal simulations for electronics in Ansys Icepak using the Classic interface.
The course devotes very little time to CFD & thermal theory and focuses on the use of the software through workshops to solve practical problems. Workshops are focused on the electronics industry and include heat sinks, amplifiers, grilles, circuit boards and include various software features such as zoomin modeling, compact models, hex dominant meshing and non conformal meshing.The import of board trace layers are also discussed and demonstrated.
Most workshops create geometry from scratch or import neutral CAD geometry as starting points. DRD encourages the students to bring a SAT or Parasolid file with them to the training (preferably a model from their workplace) for a little testing and discussion of their own problems to solve. DRD will also demonstrate the integration between CAD systems and Icepack in the Workbench environment. DRD has added a custom workshop to the course that transfers the thermal results from Icepak to Ansys Mechanical for thermalstress analysis all within Workbench.
DRD conducts this course over two days. Most of the course material comes from Ansys, Inc.â€™s three day Introduction to Icepak course. Students will receive all of these materials and can work through and reference the additional material on their own time.

Introduction to Ansys Rocky
by Mai Vang  Jul 30, 2023
This course provides an introduction to conducting computational fluid dynamic simulations in Ansys CFX.
The course focuses on use of the DesignModeler and/or SpaceClaim to prepare CFD models for meshing within the Ansys Workbench meshing environment, and then pre and postprocessing with Ansys CFX.Â
The course devotes very little time to CFD theory and focuses on the use of the software through workshops to solve practical problems. Analysis types included in the course are generally turbulent with various functionality highlighted for each one – multiphase flow, conjugate heat transfer and fluidstructure interaction with Ansys FEA, or moving boundaries, for example.
Most workshops use neutral geometry in the form of SAT or Parasolid files for starting points. DRD encourages the students to bring a SAT or Parasolid file with them to the training (preferably a model from their workplace) for a little testing and discussion of their own problems to solve. Although most exercises will use either a SAT or Parasolid file, DRD will also demonstrate the integration between Ansys and CAD systems including associativity.
Chapter 1  Overview of Workbench, DesignModeler, and Domain Extraction
Workshop 1a – Orientation of Workbench Interface and Sketching
In this workshop we introduce the Ansys Workbench environment and sketching in DesignModeler and/or SpaceClaim. A small model is created from scratch so the users gain some experience with the user interface.

This 1day course provides an introduction to electromagnetic analysis in Ansys Maxwell. This is an applicationindependent course, so it is useful to engineers looking to use Ansys Maxwell to model a variety of devices, like motors, generators, transformers, solenoids, and more.
The course commences with basic concepts including 2D and 3D magnetostatic, eddy current, electrostatic, and transient analyses. In addition to covering the different solvers and the relevant modeling techniques for each, the course will cover ways to efficiently pre and postprocess the engineerâ€™s models in Maxwell, including parametric analyses.
During the course, students will build handson skills by setting up and solving a variety of simulation models during the workshop sections.
Workshop 1 â€“ 3D Magnetostatic

Workshop 2 â€“ 3D Eddy Current
Workshop 2 â€“ 3D Eddy Current
This workshop introduces the Eddy Current solver based on a simple example with a disk above a coil. The solver calculates the magnetic fields at a specified sinusoidal frequency. Both linear and nonlinear (for saturation effects) magnetic materials can be used. Also, eddy, skin and proximity effects are considered.
Workshop 3 â€“ 2D Transient Magnetic
Workshop 3 â€“ 2D Transient Magnetic
This workshop represents a quick start to using rotational motion. It will cover how to perform rotational motion in Maxwell 2D using a rotational actuator (experimental motor) example. The workshop covers three techniques: large rotation standstill, large rotation at constant speed, and large rotational transient motion.
Section 4 Postprocessing and Parameters
Workshop 4.1 â€“ Postprocessing
This workshop will discuss how to use the Maxwell 2D Post Processor. Field plots and calculator operations will be demonstrated on an Eddy Current project. Some examples of postprocessed results in this workshop are contour/vector plots of the B field, graphing the H field magnitude along a designated path, and integrating the copper losses within the coils.
Workshop 4.2 â€“ Parametric Analysis
This workshop describes the steps required to setup a parametric analysis offered through Optimetrics. A simple magnetostatic problem will be used to demonstrate the setup. The coil current and the dimensional length of an iron slug will be varied and the impact of changes in above parameters on the force exerted on the slug will be observed.
