Introduction to Ansys Twin Builder for Mechanical Systems

one-day course

Ansys Twin Builder enables engineers to accurately and quickly design complex mechanical, power electronics and electrically controlled systems. In industries such as automotive, aerospace and industrial automation, organizations use Twin Builder to identify problems in the early design stages that other simulation or build-and-test methods cannot detect.

This course provides an introduction to Ansys Twin Builder for Mechanical Engineers. The course focuses on hands on workshops, and students solve problems ranging from spring-mass-damper dynamic systems to hydraulic systems including transient effects. Workshops also include modeling of a Pong game using co-simulation with the Ansys Mechanical Rigid Body Dynamics tool as well as use of Ansys Mechanical and Ansys CFD Reduced Order Models in fluid systems.

Introduction to Ansys CFX

by Mai Vang, Marketing Director | Jul 30, 2023

Introduction to Ansys CFX

two-day course

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.

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 fluid-structure 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.

Introduction to Ansys Maxwell

one-day course

This 1-day course provides an introduction to electromagnetic analysis in Ansys Maxwell. This is an application-independent 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.

Introduction to Ansys SIwave

by Mai Vang, Marketing Director | Jul 30, 2023

Introduction to Ansys SIwave

one-day course

This course provides an introduction to the Ansys SIwave environment of the Ansys Electronics Desktop (AEDT) Suite. The general problem addressed is that of the PCB type. The course focuses on the use of the SIwave user interface and briefly touches on the HFSS 3D Layout interface. Both of these tools are included in the Ansys SIwave Premium and Ansys Electronics Enterprise licenses. Within these interfaces, one can import ECAD geometry, assign material properties, apply excitations, perform solutions, review analysis results, and generate several types of automatic html reports. We discuss solutions to general electromagnetic problems encountered by most PCB designers. Approaches for calculating trace characteristic impedence, crosstalk, DCIR drop/ohmic loss, S-parameters, signal/power integrity, and capacitor decoupling are addressed.

Most workshops begin with projects where ECAD geometry has already been prepared. DRD encourages students to bring ODB++ or ANSYS EDB files with them to the training (preferably from their workplace) if they desire to test their own geometry.

Additional Course Details

Ansys Version used to create course content: 2019 R1
