Puoi fare anche un caso con la benzina al posto del metano che non riesco a farlo funzionare? Sarebbe grandioso se facessi anche un tutorial per una camera di combustione vera e propria con xienginefoam

Is this a four-bar linkage mechanism?

really, well informative tutorial! I have a question a "Link" option not worked and give me error as variable not recognized why?

What is DOF

Ciao, e se il file di snappyHexMeshDict invece di appoggiarsi a file stl o obj utilizza la tipologia di forme geometriche "searchable"? Ad esempio definendo un "searchableCylinder" e una "SearchableBox"? Come posso visualizzare poi la mesh completa?

how can you make the distance between CB is constant

Ciao, scusami potresti dirmi come hai settato openfoam per simulare la turbina eolica, devo fare una cosa simile.Grazie.

Great tutorial! Thank you so much! Amazing job!

Hello! Is it possible to get from you the prepared file incinerator.unv to proceed to OpenFOAM?

where could I find the WING folder to simulate the wing of the video? please.

기계원리편 만드는 과정이 보기 힘들었지만 아뭊든 잘보고 갑니다

hello is it a hallow cylinder you imported or solid?

thank you for video, but i got a qq, what if you have two inlets, will you sum both inlets pressure or you will calculate the total pressure difference?

Sei la mia salvezza

Thank you i just finished my important works and your explanation amazed me thank u

ciao, complimenti per il lavoro. sarebbe possibile avere i file ipt di questo lavoro? grazie mille

its 4_ bar??

Really great tutorial and exactly what I was looking for. I have tried to do it myself but can't get it to work. Would you be able to share the case files so I can parametrise it to my case with my geometries? Thank you in advance.

Is it possible to calculate the Inertia Matrix, Friction Effect and Gravity effect of a robot, if you know the DH parameters, using the peter corke toolbox? I have been struggling with this, please let me know if you have a solution. Thanks.

I would like to reproduce your simulation but I can not access the step file under the given link,

Any alternatives for Salone software? It's unstable and giving me problems constantly.

I want to give a certain coordinates of a point so that I want the end effector of robotic arm go to the given coordinates. What do you suggest?

sir, how to defiend q from dh table?

I'm trying to perform a simulation where I have three different gases, O2, CO2 and N2. Do you think that is possible use your tutorial, deactivating the combustion part...

Thanks for the video! very easy to follow! Is possible to you resend the link? it is not working anymore.

if i have up to q4 and p4 how should it look like i managed to have it running however it barely marks any points on the workspace, how can I make it run properly; here's my code clc clear all R(1) = Link([0 0.077 0 pi/2 0], 'standard'); R(2) = Link([0 0 0.130 0 0],'standard'); R(2).offset = 1.389282; R(3) = Link([0 0 0.124 0 0],'standard'); R(3).offset = -1.389282; R(4) = Link([0 0 0.126 0 0],'standard'); KR= SerialLink (R); conv= pi/180; i=0; for q1= -360*conv:10*conv:360*conv for q2= -180*conv:10*conv:180*conv for q3= -90*conv:10*conv:90*conv for q4= -90*conv:10*conv:90*conv aAb=trotz(q1)*transl(0, 0, 0.077)*transl(0, 0, 0)*trotx(pi/2); bAc=trotz(q2)*transl(0, 0, 0)*transl(0, 0, 0.130)*trotx(0); cAd=trotz(q3)*transl(0, 0, 0)*transl(0, 0, 0.124)*trotx(0); dAe=trotz(q4)*transl(0, 0, 0)*transl(0, 0, 0.126)*trotx(0); aAe= aAb*bAc*cAd*dAe; i=i+1; p=aAe(1:3,4); p1(i)=p(1); p2(i)=p(2); p3(i)=p(3); end end end end figure(2) plot ((p2.^2+p1.^2).^0.5,p3,'b.'); xlabel('x') ylabel('z') figure(3) plot ((p1.^2+p3.^2).^0.5,p2,'b.'); xlabel('x') ylabel('y')

Hi guy. I do not think the link is available. Could you check it?

Really apreciate the help

Please complex robot arm design do it by the inventor software.

What tool box is used for this

How did you calculate the area value?

Excuse me, Sir! I follow your video but face some errors, how can fix them? the error is： Error using SerialLink/plot (line 206) Insufficient columns in q Error in youtubetest (line 14) ST.plot([0 0 0 0 0]); My code is here： L(1) = Link([0 0 0 -pi/2], 'standard'); L(2) = Link([-pi/2 0 400 0], 'standard'); L(3) = Link([pi/2 20 0 pi/2], 'standard'); L(4) = Link([0 450 0 -pi/2], 'standard'); L(5) = Link([0 0 0 pi/2], 'standard'); L(6) = Link([0 70 0 0], 'standard'); ST = SerialLink(L) ST.name = '6_dof'; ST.plot([0 0 0 0 0]); Best, Thank you!

Hi~ Your tutorials really help me do OpenFOAM self-study. However, how can I get the case files including 0, constant, system folders for each case? Do I have to create them by myself for all the tutorials? or can I get them somewhere? (For your reference, I am using openFoam v.9) I am openFoam beginner, so if I have to create them all, it is so hard for me. So, can you please upload the cases files for each tutorial?

Thank you so much, please can I contact you through gmail or whatsapp?

Thanks so much.... it's amazing...

grazie mille per la playlist, mi è garbata un sacco

Excellent videos. Maybe a little bit more explanation of commands for beginners would do great and if you could speak a little slow. Thank you so much.

Hi, quite nice work. Just wondering if you have any case using OF2112 for simpleReactingParcelFoam + combustion?

Thank you very much for your tutorial. As other said, your combustion tutorial is among those few tutorials I can find in youtube. However, when I tried to download the file. It was said that "Sorry, the file you have requested does not exist.". Could you assist this issue? Thank you very much once again.

perfect

hi i have another question. i have successfully do a complex trajectory of a robotic arm just like in the video but is it possible to find the end effector coordinates of the system? maybe its already there but i couldn't find it yet. this would be very helpful as i am doing a simulation studies for my final year report. thanks in advance!

Hey man, I have found your video very helpful, I just have one question, thhe program runs as normal and it shows the plot for my robot but I dont get the matrix on the command window, do you know why it may be? Thank you!

hi, i have a question for the second part. how did you define vectors of q0 to q1 to q2 to q3 vectors for jtraj? thanks in advance!

Thank you so much!

Good work, thanks for sharing The language appearing is it Italian?

why incompressible? is it accurate?

to those who have problem with 4bar angle position, please use this video. Really helpful..Thank you!

thank you it was very helpful

Which softwere is that?

Hi, thank you so much for the tutorial. I have one question. Is it possible to add more than one waypoints? So the robotic arm can move in a zig zag motion from top to down for example.
