NX CAD vs. Simcenter STAR-CCM+

NX CAD is very good when it comes to three dimensional modelling and rendering and visualization. Furthermore, the export to jt function together with import into other Siemens software packages, such as Teamcenter, is a major reason why I am using NX. However, it can be a little more computationally expensive compare to other CAD packages.

The applications that I have been using it with in terms of flow and energy and temperature distributions and coupled solvers, segregated solvers, these kind of areas if you need that, those kind of solvers, it's very good. It's very robust. Maybe on the combustion side, it could improve, especially if you have these kind of tabulated solvers that you want to use, not the detailed chemistry, then it becomes very difficult to get some results from it. And do you trust the results or not? That's always the question on that kind of application, something that I could think of really fast.

• Seamless interaction across multiple departments.
• The software allows you to create a very high level of control and organization within your engineering staff. This reduces the companies mistakes and maximizes productivity.
• The software makes it very easy to track your product through every phase of the production cycle.

• Meshing, for instance, it's very easy to mesh, try different approaches to meshing. Traditionally that's a very difficult job, but in STAR-CCM+ it makes it very easy and very reliable. Post-processing also is very nice and in all the modeling, the physics that you can carry out and you can simulate is also very, very nice. I tried to move to the priorities that does a good job. All in all, it's a very good software.

• Keeping the colors of surfaces if volume bodies are linked
• Show and keep symbolic threads
• For me, I miss more information why a surface can't be deleted or a radius is not possible. And maybe a solution, how could it look like, if NX CAD adds a new surface.

• Implementing physics like Cox-Voinov model
• Mesh related stability issues
• Chemical & plasma physics
• Integration with other products from Siemens (similar level as we have with Abacus)
• Speed up the lagrangian solver
• Improved guidence on uFluidics & evaporation models
• Interoperability (HEEDS, AMEsim, System Modelling Workbench but also with non siemens products and open source codes required for LBM, DSMC, PIC, DFT...

It works very well for our organization. It has made us much more productive.

Siemens NX CAD has been has been simple in design & user interface. It is best among the competitors. It can develop heavy models & designs with very ease. It has Layers options for arranging multiple assemblies in the same file. It does not require heavy system investment & works fine on professional PCs

Great single window GUI

NX CAD version is going out of support after only 12 months. Changes will not be implemented after 12 months from prodcution

Our designated support engineers do a proper job. On the outdated Help file and training material there is a lot to gain

Need more clear training

It is super easy when it comes to implementing it.

I like NX CAD modelling features and drafting tool bars which helps in accomplishing the task in minimum steps. The available tools precisely generate the splines and complex geometries as required. There is perfect integration between NX CAD and NX CAM modules with less data loss. Better graphical interface and simplified commands makes NX CAD a better software then others.

• Through API implementation we have created some CAD Automation tool that saved us about 100h to create specific 3D geometry
• Teamcenter integration leverage quality of 3D geometry because avoid any situation of duplicated version of same Item that can take lot of hours to verify the correct version
• Possibility to integrate different 3D format allow to earlier detect possible impact of wrong geometry

• Time saved in creating a inhouse code, tens and tens of hours.
• Time saved in experimental setup, tens of hours.
• Does add some time in testing to confirm star is doing what you think it's doing, but an overall net gain in productivity.
