3E - COMSOL simulation of electrostatic potential

[@PhysicsNinja]

Particles do not follow steamlines. This is only true for straight streamlines. The streamlines are always parallel to the fields and therefore the forces are always parallel (or antiparallel to the fields). You can't go around a curved field line if a force is tangent to a field line.

24:34 the real benefit of doing parameters is that it can help us when we do parameterized simulations.

Hi Can you comment on how to determine the partial discharge inception voltage if the presented model is considered.

[@alinittos]

The parametric sweep did not work because the name of the parameter. 'V' is a special name in Comsol; naming the paremeter vo, or vol, or super_man works

while extracting the surface plots can we adjust the x range so that there will not be any white spaces in the final graph. suppose for the surface plot the x range is from 0 to 90 but in the plot it is showing from -80 to 160 so there is extra blank space to the left and right of the surface plot.

Sir.How can I choose boundaries, and how I make the simulation periodic plz help me

[@aichatouhami8467]

Please how To draw needle /plane in comsol and evaluation of distribution electric field

[@raghunadhasastryrentachint8753]

How 2 circles are placed side by side

[@prakruthihl7485]

Superbly explained thank u soo much sir.

[@a.s.i1298]

God bless you Prof. thanks a lot for helping me understand.🌹🌹🌹

[@andreykuznetsov6226]

Super! Thank you so much 👍

[@bestof1808]

is it electrospray?

[@RoamerSonu97]

Sir how to save the auto generated report by comsol multiphysics

[@rameshr5272]

Could you please say that in the charge conservation part, some of the domain shows like (not applicabe), could you please say and why? how to clear it ?

[@wendlermatos2186]

Excellent video.

[@raghunadhasastryrentachint8753]

Sir could you please explain how to simulate a hvdc transmission line

[@newmail3549]

thanks your your nice work, any explanation for table graph?

[@kamalpreetsingh6810]

Hello sir .......i need your help.... I want to do electrostatic induction process (charge transferring by touching) in comsol multiphysics....please guide me

[@hanig8860]

Can you tell me when I should choose the "electrostatics" and when I should choose "electric current" module? Can we find the electric field in both modules?

[@MBLabWSU]

Electrostatics will solve for voltage, electric field, and charge, but not current. The current module will solve for all of them.

[@hanig8860]

How good is this video!!!! Thank you. I wish I had a chance to be your student.

[@aichatouhami8467]

I appreciate your efforts To teach comsol please can you explaine how to plot the graph of electric field vs distance

[@popualima5258]

Sir, can you explain again how to plot the graph? Thank you

[@Anas-hx6rv]

Sir please make a video on how to analyse fringe feilds in capacitance and pls also provide us study about how to plot graphs

[@ajithkumarbs7640]

Nice explanation sir.! Can you guide me how to calculate average electric field magnitude from the results.?
