Hi, can we do Similar steps for alkaline electolyzer ?

Dear Mam, how to solve the Allen Cahn and Cahn Hilliard equation for 2D and 3D BOTH. What is the exact equation for Allen Cahn and Cahn Hilliard for both 2D and 3D which I can use in COMSOL. And also, what are the parameters?

Hi, can you define, how to put counter-current flows and variable flow channels, I want info regarding the flow direction as well as type of flow channels. Thanks

I’m getting error as “Unknown function or operator : D”. But I have defined D in parameters1

How can you calculate the specific surface area?

How did you come up with the Algebraic formula? r2 = 2 * s - r1; Because I could only think of a for loop brute force approach.

Please upload video on a single bubble nucleation from cavity due to nucleate employing level field or phase field coupled with heat transfer fluid. Thanks. Your videos are awesome

hi madam please can you make video on single bubble inception from cavity due to nucleate boiloing employing level set method. Please madam it is earnest request. Thanks

great thanks for video..................only one important questions that puzzled me in this expression -cs*TxDs where Tx come from and what does T refer to?

Thanks so much for your helpful tutorial！！

Please tell some important points for electric field in capillary tube.

Thank you for the tutorial! Why is it that we described inlet velocity as a function of time? In the examples of Von Karman vortex street that I saw on books it is uniform flow. Thank you for your answer

hi how you doing. do you use the particle tracing laminar flow that generate random particles?

Thanks a lot, Jessica, your video is very insightful. Even though the flu was disturbing you but you managed to complete your tutorial effectively🥰

Thank you very much could we have related tutorial on the Stacks of the Fuel cell

Thank you for sharing, but it would be better if you could clarify from the beginning that following your steps will not yield the correct answer.

Hi Professor Jessica, I am Dr. Naeem Faraz from Shanghai. I am working on this problem. If I need to discuss or need your help, how can I contact you? Any email or whatsapp or we can have zoom meeting.

how to make the geometry of the taylor cone problem?

Hello, i love your tutorials, is there any chance of doing comsol tds on 3D with java programming (from inside the comsol gui ) ?

Hi, I am struggling with a problem, can you please tell me how to make periodic boundary conditions for discrete points for the truss in Comsol manually

I have some doubt would you sharing your email address ?

Can you make a video by changing materials please?

When I add domains, Membrane and Anode GDE are not applicable. What to do?

thank you very much for the video, a doubt can you design a drum type drying in comsol? could you explain me how please and thank you

Hey Jessica thanks for the tutorial, if possible please give a simulation video on laser keyhole welding or laser ablation

Mam, Could you please share droplet parameter file mam.

Hello if we increase the temperature the program is not working and error occur. please tell us how to solve the problem

Hello Jesica Currently in Germany, there are licensing issues regarding downloading software such as COMSOL Multiphysics. Could you provide any links related to downloading this software? I am aware of these restrictions and am seeking a solution, such as a trial version or academic license. Thank you.

Hi, I was trying to simulate adsorption with the module in Comsole. But it's as if the program doesn't read the adsorption at all and I'm left with a block at essentially the same concentration and it doesn't do anything for me

Hi Jessica, thanks for walking through this. One thing to note when writing out the ODE for mesh displacement. The variable "spf.vn" is NOT the phi velocity component. After some digging in equation view, I found the variable under the "Fluid-Fluid Interface 1" boundary condition. The variable "spf.vn" is the Normal Mesh Velocity at Boundary 11 - the droplet edge arc. Not to be confused with "spf.nv" which is different. The full expression for it is below, which amounts to the dot product of the quantity (velocity field vector on the down/inner side of the boundary - (mass flux scalar/density scalar)*interface normal vector) with the mesh normal vector. (Apparently XD) that gives the total normal mesh velocity in Comsol language. spf.vn = (down(u)-spf.Mf*spf.iNr/down(spf.rho))*spf.nrmesh+(down(v)-spf.Mf*spf.iNphi/down(spf.rho))*spf.nphimesh+(down(w)-spf.Mf*spf.iNz/down(spf.rho))*spf.nzmesh So I believe the ODE is a way of telling Comsol to track the instantaneous change of the mesh displacement as the total velocity at the point where the droplet meets the glass. Effectively as the simulation solves, it tracks the total mesh displacement by integrating up all those small changes over time. The two expressions used for Prescribed Mesh Displacements are written to link the geometry radius Rg to the initial placements of the droplet (at one multiple of R0) and the glass disc (at 5 multiples of R0). The initial width of the exposed glass disc is then 4 multiples of R0.

Its possible to simulate von mises stress in a underwater drone?

Its showing avoid inverted mesh elements please help me

Mam please demostrate Transient Elastohydrodynamic squeeze film interaction

Thanks for this amaizing video , can you send parameter files please

Hi I want to simulate some nested cylinders that inner of them is a heat source. how can I do geometry of it? can you help me please?

Hey Jessica! Can you explain why u multiplied by 2 the p_laser? I mean how u got 2, before the p_laser.

Please find reference pdf in video description. Also, as additional resources have been requested in comments, please reference my thesis publicly available at repository.mines.edu/handle/11124/172355

hi! can you mae a tutorial for particle deposition inside a sphere or porous media ?

Hello good night can you share file geometry taylor cone?

Firstly, I would like to say ' Thanks so much'. Can I have this reference pdf? Please🙏

Can you please share the pdf

Wonderful tutorial! Ms. Hoffman, Thanks very much.

Hi, thanks for the lesson! When I enter a1=k_ads*c*(Gamma_s-cs)-k_des*cs in the field, it writes "unknown variable cs". Because of this, the compute button throws an error. In addition, in the Flux1 field I have No,c written instead of J0,c. Please tell me what's wrong? I'm using version 5.1

May you make a tutorial for droplet movement when charged fibre generates an electrostatic field?

Thank you for your nice explanation!

Hi ! can you make tutorial about unit -cell with nodes and different forms .. in COMSOL

Thank for the inspiring video..Could you teach me how to change the gas?
