Any good CFD tutorials for stardesign and star CCM out there?

Click For Summary

Discussion Overview

The discussion revolves around finding resources and tutorials for learning Computational Fluid Dynamics (CFD), specifically focusing on software such as Star Design and Star CCM. Participants express a desire to understand both the practical application of these tools and the underlying mathematical concepts related to viscous flow and the Navier-Stokes equations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant expresses a need for good CFD resources due to a lack of adequate coursework at their institution.
  • Another suggests using OPEN FOAM as an open-source alternative and emphasizes the importance of understanding the mathematical foundations of CFD before using software.
  • A participant mentions the Navier-Stokes equations as fundamental to understanding viscous flow but seeks guidance on which specific topics to study further.
  • There is a discussion about the complexity of the Navier-Stokes equations and the challenges of obtaining accurate results in CFD, with some suggesting that Euler equations may be used instead in certain cases.
  • One participant provides a link to a write-up on the derivation of the Navier-Stokes equations as a resource for background knowledge.

Areas of Agreement / Disagreement

Participants generally agree on the importance of understanding the mathematical principles behind CFD, particularly the Navier-Stokes equations. However, there is no consensus on the availability of effective tutorials for Star Design and Star CCM, with some expressing frustration over the lack of helpful resources.

Contextual Notes

Participants mention limitations in their current educational resources and the challenges associated with learning CFD software without a strong mathematical background. There is also a recognition that practical CFD applications may not always align with theoretical expectations.

Im really trying to learn CFD since embry riddle does not have a good course for undergrads to learn some basics about viscous flow..Im really trying to learn CFD since aerodynamics in general interests me a lot. Does anyone have good resources to learn some CFD software ( namely star design , star CCM since my school uses it)
 
Physics news on Phys.org
If you have a Unix system you can use the OPEN FOAM cfd program. It is open source software available here

http://www.opencfd.co.uk/openfoam/

Thers isn't a version for Windows yet.

Before you jump into a software program, you should get familiar with what CFD is from a mathematical standpoint. That is how I got started. The book I used is this one.

Unfortunately, I never had any luck finding good tutorials for programs like Star CD or FLUENT.

Thanks

Hello thanks for the response. As far as knowing what they are from a mathematical view. To my knowledge they are the Navier Stokes equations which is just a general version of the Momentum and energy equations , including heat and shear effects to the flow.

I don't really know how to get to involved with the mathematics side of them, Is there a topic I should study in depth for viscid flow?



Also would anyone else know where to get Star CCM / Star Design tutorials/help. I did the tutorials included but they are short and unhelpful.
 
The Navier Stokes are the three "laws" of physics, conservation of mass, momentum (in all directions) and energy. This gives 5 coupled, partial differential equations.

They are very important to know inside and out before starting CFD because you will NEVER get the correct answer in CFD. you need a solid understanding before attempting to resolve any solutions.

Having said that, the distances associated with viscous flow are order(s) of magnitude smaller than the mean flow. So, getting good viscous results are kind of a pain in the ***. In fact, more often than not, we find ourselves solving the Euler equations rather than the full N-S which do not have viscous effects.

Eithre way, before diving into any software-specific tutorials, get a good background. Check out a little write-up I have for some decent background specifically on the derivation of the NS equations.
