It is hard to believe that a year has passed and it's time to update you on what’s new for ANSYS 18 fluid dynamics. There is so much to write about and so little space in this blog!
I’m tempted to detail our breakthrough Harmonic Analysis method that produces accurate turbomachinery simulations up to 100X faster. Or I could focus on progress with Overset Mesh that speeds and simplifies simulations with moving parts. But that is not news, that just expected. ANSYS has been delivering new levels of accuracy and advanced modeling capabilities from the beginning. Instead, I’m going to shine the spotlight on an area you might not expect from ANSYS: Ease of use.
I see computational fluid dynamics (CFD) usage surge as more companies understand the value and insight that it can unlock in their products. This growth is happening all over but especially outside the traditional sophisticated CFD strongholds such as aerospace and automotive. With this growth comes many companies new to CFD who may lack the deep experience found in long time users but they don’t want to give up any of the accuracy or wealth of models. Now ANSYS 18 makes it possible for less experienced engineers and companies without deep resources to take advantage of the dramatic benefits available from CFD simulations. To this end, ANSYS AIM’s fluids capabilities have been greatly expanded, including support for non-Newtonian fluid viscosity, fluid momentum and even fluid transient flows (beta).
But many CFD problems need more.
In this blog, I’m going to describe two advancements that I’m really excited about: ANSYS AIM integration with ANSYS Fluent and simulation apps. Learn about the rest including the accuracy and advanced modeling in my ANSYS 18 Innovations Fluids webinar February 16th.
ANSYS AIM integration with Fluent provides easy prep and meshing, and facilitates collaboration
Many large companies have initiatives for design engineers to perform upfront simulation as part of the product development process. This frees up simulation experts so they can perform more advanced simulation and integrate simulation guidance into the early phases of the product development process. In these companies, design engineers often need to send their simulation models to simulation analysts to perform more advanced simulations, including additional physics, or to validate their upfront simulation results. Reliable data transfer between simulation tools used by design engineers and simulation analysts is required for accurate and efficient data transfer to streamline the product development process.
In ANSYS 18, AIM includes enhancements to support robust and accurate simulation data transfer between design groups and simulation analysts. AIM can transfer mesh and selection set data from AIM to Fluent via a Workbench project schematic connection. New AIM templates are also available that enable a guided workflow and automatic creation of the Workbench schematic connection to the downstream analysis system. These new capabilities enable design engineers to quickly transfer model data to simulation analysts, which enables engineering collaboration, thus streamlining the product development process.
AIM is included with the new ANSYS CFD Enterprise, a comprehensive tool kit for experienced engineers and analysts in large organizations who need to solve the toughest CFD problems.
ANSYS 18 fluid dynamics simulation apps improve workflows, speed results and provide best practices
ANSYS Computational Fluid Dynamics (CFD) solutions deliver fast, accurate results across a wide range of fluids and multiphysics applications. But the CFD field is extremely diverse and many problems require training and best practices that go beyond the basic software solution. Simulation apps enhance the capabilities of the basic software with pre-validated packages that extend the capabilities. Apps deliver faster, better simulations by automating workflows and problem set-up, capturing engineering simulation best practices and company-specific workflows, and providing focused application-specific solutions. Apps are written by ANSYS, partners, consultants, universities — you can even create (and sell) your own.
As a result, engineers benefit from the ANSYS ecosystem so they can spend their time solving problems, not searching for solutions. Now ANSYS 18 fluid dynamics expands the use of simulation apps with CFD so they can be used with ANSYS Fluent.
Visit the ANSYS app store and take a look at the many apps available today to enhance your CFD simulations. Here are some examples of what you will find.
- Pump Modeler provides easy-to-use and automated workflow for creating gerotor pump geometry decomposition, generating meshes and running simulations with cavitation in ANSYS Fluent, and producing a comprehensive custom pump report.
- ANSYS partner EDR Modeso offers the FSI Transient Load Mapping app to speed analysis of fluid-structure interaction (FSI) problems by mapping transient CFD results to thermal or structural analysis, including the definition of load steps.
- Workbench Poly Meshing for Fluent Ties the advanced polyhedral meshing capability of Fluent Meshing to parametric and familiar environment of Workbench Meshing.
- Wind Tunnel Design provides a simple, guided workflow to simulate aerodynamic effects in ANSYS AIM.
