  How to get lift coefficient

• 
  @kongolandwalker4 ай бұрын

  That is exactly what i was serching for, but changing colormap of any object changes ALL colormaps, even in separate pipelines. Upd. I found button which looks like pallette with broken link, it allows to do separate colorings for different things. But i don't see the button in the video, it might have been added later.

  When i go to block indices just appears a block called internal mesh, how a can create more blocks? I made mi simulation using a .obj in openfoam, i edited mi model in 3ds max

  Thanks for this nice video ! However I encounter a problem, my object (plane in the video) is not present as a block when I want to extractBlock, what do I need to do in my geometry to make it appear here ?

  I hope I'm not late. Yo have tu clivk in your .foam and then scroll down until you see your mesh regions. the you have to enable your surface.

  Thank a lot for the video but I have a question: I have a stirred tank with an emispherical bottom where the origin of axes is a the lowest point of this bottom, to evaluate the torque, should I change the cross product? Or does it remains always "0*iHat+0*jHat+0*kHat-coords"? I hope my question is clear. Thank you very much in advance

  I think I agree with you, but I am not sure. To get the total lift force the pressure load on the mesh face should be multiplied with the mesh face area.

  @@lucderuiter8904 To be more precise, if you change angle of attack with velocity vectors this procedure will give Normal and Axial force. On the other hand, if you change angle of attack by body rotation it wil give Lift and drag force.

  Hi, I tried this on one of my projects and the integrated values are showing the drag values without considering the viscous effect. Is it possible to get those values too, the software I did the simulations showed both the drag due to the pressure force and the drag due to the viscous effects. How do I get it on Paraview?

  @professionalprocrastinator810311 ай бұрын

  It's a late answer and you surely have figured it out by now, but for reference you need to have or compute the wall shear stress then include them in the calculation of the forces

  Hello friend, this is a good video, I learned from you. Only one thing, torque is a product of rxf and in your video you put Fxr.

• 
  @RzogL2 жыл бұрын

  Yes, but he was also defined r from the origin to the force application point, which is the wrong way round. Since AxB = - BxA, his Fxr works out the same as RxF, if R is defined as coords-0*iHat-0*jHat-0*kHat.

  Hi! Thanks for the video. I would like to make you a question. For the incomprensible case, the pressure is usually not in [Pa] but it is divided by the fluid density (so the unit is m^2/s^2). On that case should we multiply the pressure for the density in order to have the proper pressure? (and the proper forces). Second question. I am calculating the forces exchanged between a boat hull and the water (so density=1000 kg/m^3). Should I use the same formula multiplied by the water density or should I use the same formula? Thanks in advance for the answer!
