I used turbulent flow add gravity in comsol but not convergence 😢

what if I have to apply load on not whole body but some particular part on that plane

I had issues with mine it say undefined materials property so what is the solution now

Hi! Whenever i am attempting to do compute after adding study, my COMSOL crashes within seconds like i pressed compute and within a second the window is closes and i am brought to the desktop. I am using COMSOL 4.4 with a RAM of 32GB . And i followed exact steps just the way you did in the video. Could you or someone help in identifying what is the issue here?

Hello. For a 2D laminar flow, what should be the expression for wall shear stress? spf.mu*spf.sr or what else? Some parts of the wall are not perpendicular to x or y axis? Does it make any difference?

Hi sir thank you for the simulations, i want to ask you please about something in comsol, i can pay for

ruclips.net/channel/UCmN4qjLMN17BSf28R_0m6Eg

Please make a video on optimisation of laminer flow 😊

I'm having a problem with a simulation with Comsol Multiphysics Can you do the simulation How much is the service

you are saying comsol is finte volume software is it right or it is finite element software

thank for the video!!!!!!! can you please share the song from the intro??? very cool music

Do we need to apply in TCS as well or tcs will approach to us according to our marks. Like we apply in other companies

version of comsol? please tell me

thanx man that helped alot

sir you are doing great job can you please make the videos on optimization using comsol

How can we do a symmetric model analysis in comsol for heat transfer look like this example?

Excellent tutorial and clear explanations! Easy to understand and pronunciation is also clear for me to understand. Thank you!

brilliant

Sir I am simulating argon gas flow through nozzle for the turbulent case.When I use steady solution I get the results but when I choose transient I get an error that last time step is not converged plz help

I got my result got 67 % I have completed post graduate in 2017...can I apply ?

how to find the fatigue point?

Greetings, sir we have to oil into water and water into oil emulsion in comsole, can you guide us related this ?

Thanks a lot!

Great tutorial! Can you suggest how to add loads that are dependent of structural deformation, eg. aero-elastic loading on a wing

Awesome explanation

hey , how xe coul calcul the reynolds numbers of o figure please

HOW TO BUILD THE PIPE NETWORK PLEASE ?

Sir, can you please tell how to find surface resistance( electrical contact resistance) in COMSOL. I m doing a project on spot welding. I need to find the surface resistance between steel and aluminium.

Can you please add calculations of shear stress and shear rate at wall at different z values ? Thanks

Hi. How do you estimate shear stress at wall after solution is obtained ? I see only velocity and pressure as output. Thank you

Thank you for nice tutorial. I have one question. If you have only one 90 degree bend and one side is immersed in tank w say 100 L water. Other end of the tube is connected to pump with flow rate of 5 L/min. How do I solve such problem for shear calculation ?

Does applying flow physics on the model make the model only work on solids? Because I've made a hydrocyclone in Comsol but I only get results on the parts that I made solid? I thought it was because of the wall defined in the physics but I am not sure.

Bro after TCS nqt results will I apply for TCS hiring ???? Please reply

Thanks a lot...very helpful.

Thank you .

I have got 64 percentage in nqt it is useful or not for getting interview

Is there a way to measure total flow as you would with a closed loop in amperes law? I would like to design different geometries to maximize overall flow in a system

Please sir can you make video of fluid flow in porous media and subsurface flow (fracture flow) section??? In comsol multiphysics?

i got 97% in cognitive and a bit more than 65 in programming but did not receive any mail what to do brother?

How to update secondary and higher secondary marks, please tell me

Could you if it is possible simulate fluidized bed reactor solid liquid with adsorption with isotherm model

In my case Boundary condition only include pressure, velocity , mass flow, and fully developed flow and not the condition for laminar flow. How do I check for entrance length effect in laminar flow ?? ???

Sir thanks a lot for your video... Sir i have comsol 5.6 and in boundary condition it is showing fully developed flow rather than laminar flow... So please guide me what can i do for it to get the laminar flow results.

Please tell me how we add fixed bed in this cylindre

could you please send the geometry on mail?

Hello thank you for the nice work, very explenatory. The tube is solid or empty? I am trying to reproduce the problem but I cannot take the same picture with the ribons. thanks

Please let me know this: My percentage in class 10 is below 60% but as I got to know from tcs next step portal 60% is mandatory and if only I would have known this I wouldn't have spend 1000 rs Now, please let me know if there are any chances for me because if nqt doesn't have any percentage criteria but tcs does then what's the point it will still be remaining the same

Sir! 8:40 From where did you get 20000 and 6,6666?

Could you please tell how to become subject matter expert at TCS ion? I have tried to figure it out but not able to find out the process for it.

Sir i am studying for the effects of roughness on a circular microchannel. I want to create the entire rough surface on the inner surface of the channel. I have my conditions as: Outer diameter- 0.282mm Inner diameter- 0.123 mm Length --- 140 mm Roughness height--- 1.4 micrometer standard deviation-- 1 micrometer. Please provide me a demonstration on how to create the model with rough surface and study the heat transfer characteristics. It will be you major help sir.
