At CD-adapco, we have spent many years working to bridge the gap between disciplines by developing techniques to effectively communicate results between different physics. With the release of STAR-CCM+ v10.06, we allow you to more easily perform flow, thermal and stress problems using the finite element based solid mechanics capabilities.

With the release of v10.04, the live update of the solution is now also made available with Optimate. It allows you to get a high level view of your design study in real time, showing you which cases are in progress and which are complete. Not only do you see the status of each design point but while your designs are running, you can connect to them and flip through updating scenes and plots to see how the results are evolving. This ability to not only better understand, but also to take control of your design during your Optimate study ensures that your computational resources are put to good use running the designs that really matter.

As we have developed STAR-CCM+ we have always worked to provide a tool based on the philosophy that integration allows the engineering analyst to cut down simulation time and cost while expanding application scope. With v10.04, we make a huge leap forward in these aims, with the release of a finite element solid stress solver to provide computational solid mechanics capabilities from the same integrated user interface you are already very familiar with.

So why did we develop this solid mechanics capability in STAR-CCM+?

With the release of STAR-CCM+ v10.04, we are providing a powerful, and unique, new feature that will allow you to gain greater understanding of your flow and thermal analyses. For the first time, you will be able to use the adjoint solver to look at sensitivities not only within your fluid domain but your solid also. By taking account of more of the physics in your sensitivities, you can now use adjoint to help provide a better optimized design, earlier in the product development process thus reducing the risk of failures and costly product recalls.

In v10.02, we have a new feature, adjoint error estimation, which leverages the power of adjoint to highlight discretization errors in your mesh that may be due to inappropriately sized and distributed cells. These discretization errors may, in turn, affect the accuracy of your engineering results.

In my last blog I spoke about some of the improvements to our design exploration tools. For version 9.06 of STAR-CCM+, we have worked on another facet of design exploration, by improving the usability of our mesh morpher which allows you to more easily perform free-form, non-parametric, deformation of your geometry.

At the beginning of the year we released the mesh deformation model which enabled you to change the shape of your geometry using morpher. This is an important capability as you may not always have access to the raw CAD data, or indeed the software required to modify it.

During the opening session of the STAR Global Conference earlier this year, Didier Halbronn, CD-adapco Vice President of European Sales, spoke about our ongoing commitment in the field of multi-disciplinary design exploration (MDX). In this blog I want to highlight a couple of new features in v9.04 of STAR-CCM+ that approach this in different ways.

One of the greatest challenges of engineering analysis is the ability to understand how changes in geometry and flow features might influence your system’s performance. For a long time, the only way to gain insight into the sensitivity of engineering objectives to changes in input was to run multiple analyses and then dig through the results. The introduction of the adjoint solver in STAR-CCM+ v8.04, however, changed that - allowing for direct access to sensitivity information from a single simulation.

How do you ensure that methods developed in one part of your organization are deployed by engineers working elsewhere?

Introducing the Simulation Assistant

To answer this question, CD-adapco have developed the Simulation Assistant, an interactive user interface that allows you to capture best practices and deploy them across your whole organization, ensuring repeatability of process and guaranteeing consistency of results.
