Very helpful tutorial. I used your lesson to help me complete a project for a Computational fluid dynamics class at my university. Thanks!

[@David-ez1fp]

Your a life-saver, thank you so much for showing me how to use STAR-CCM+

[@hassanahmadsheikh5130]

Very helpful tutorial indeed one of the best i have watched on YT

[@hiuhongfelixling1764]

Very helpful tutorial. Thank you so much!

[@JamesVestal-dz5qm]

I put mesh on my cube, but now its refusing to run my simulation because automatic mesh insists on 3d meshing and im simulating 2d cavity flow.

If I were to make a moment coefficient report which Frontal area would I use

[@luscrooge828]

good video and especially nice for the plot of AOA

[@benwright945]

Very helpful. Thank you.

[@fukairen9601]

I'm trying to use overset mesh, which dont need to remesh every time, but have no idea how to create an automation AoA sweep

[@hanfiball4136]

Great Video, thank you very much. Just one question, why do you use different frontal areas for lift and drag? As far as I am aware you should only use the one in y-direction

[@LOL_27]

Really helpful tutorial.Thanks

[@almostded325]

awesome video!

[@nateshshashank]

Super stuff!

[@711vamsi5]

I am trying to find a correct mesh size for my simulation and was hoping to do that by calculating force coefficients for different mesh(base size). how can i get the force coefficient from star ccm ?

[@vishalsehra8563]

very helpful tutorial.

[@smtcfdsimulations8126]

very nicely done tutorial

[@giuseppeocchipinti6875]

How did you automatize the remeshing required at every angle changing?

[@kouinli3533]

This really helps me a lot. Thank you! But I have one question. How can I get average Cl in the design manager since Cl fluctuates at high AoA?

[@vanduyenvimaru6835]

Thanks to your tutorial. Could you please show me how to export the mesh from StarCCM?

[@vanduyenvimaru6835]

@@siemensdiswstudentcompetit5102 Thanks for your reply

[@MartijnvDorst]

This really is a great video! Could you maybe share the table file of the Cp data?

[@MartijnvDorst]

Can you maybe make a video about more explanation about the Design Manager Project?

[@GOAFPilotChannel]

the reference area should not change with aoa and cd should use the same frontal area as cl

Hi, how do you do this?
