PTC Creo vs. Simcenter STAR-CCM+

I wouldn't suggest it to my worst enemy. My colleagues worked with other CADs and, in my experience, complain every day about this CAD, about how much things it doesn't have or do, etc. One of them keeps telling me, in their opinion, how even CREO Direct is far superior, easy to use, faster and better. In my opinion, it's a CAD that requires constant attention at what you do, how you do, when you do because it doesn't do it for you.

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.

• PTC Creo contains many advanced tools with better optimization for creating part models and other production related drawings.
• The initial concept designs can be done more adequately.
• The parameters of 2D drawings can be changed easily by editing the 3D model.
• The productivity can be increased by customized tools for modeling.

• 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.

• Providing guidance through using tools is lacking in Creo. There is a small area where the text is displayed at the bottom that is supposed to help guide you, but many times the guidance doesn't make sense.
• Layers are a hassle in Creo. Unless you know how to set up your config file to do it automatically, you have to add each item to the appropriate layer.
• There is a lack of automation in Creo. In some other CAD packages, you can add holes or the like on a pattern of features. Not so in Creo.

Incentivized

• 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...

Great single window GUI

I liked the training manuals I used to learn some, as I didn’t have CAD background in college or before this job. My coworkers were able to share with me what they learned in PTC training and I was able to get support online and through reading.

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 On the outdated Help file and training material there is a lot to gain

It is super easy when it comes to implementing it.

PTC Creo is much better than other software at allowing collaboration across multiple users, even multiple plants/locations. We went from an older non-parametric industry standard software to PTC Creo because we could save massive amounts of time by using the parametric assembly features of PTC Creo along with the the Windchill drawing organization functions.

• Having PTC Creo as our primary tool positions us as forward thinking and creative in the eyes of our clients.
• PTC Creo constantly evolves in the ability to increase our productivity; new capabilities and features are added, which reduce our level of effort for some tasks.

Incentivized

• 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.
