Please share that files to me. I'm not good at cfd so I want to show your work and understand how to do it.

can you please help me with udf? as it is not working. some of the syntax shows unknown.

Hi , would it be possible to get your contact information?

I am running a 2D transient simulation(VOF Fluent) in which vapor bubbles are generated at the bottom surface of a rectangular domain that is initially full of water with heat flux given at the bottom wall. I was trying to patch a single vapor bubble by creating a hemispherical region. I can see my volume fraction contour with the bubble after patching a hemispherical region at the bottom of the liquid. The simulation is also running perfectly when I click on "Run Calculation". When I do this same bubble patch operation through a DEFINE_INIT UDF, I can see the bubble getting patched in the vapor phase contour, but the calculation is not running. It is giving the following error in the 1st iteration itself. Divergence detected in AMG solver: vof-1 Divergence detected in AMG solver: x-momentum Divergence detected in AMG solver: y-momentum Divergence detected in AMG solver: pressure correction Divergence detected in AMG solver: pressure correction Divergence detected in AMG solver: temperature UDF code #include "udf.h" DEFINE_INIT (init2, domain1) { Message("solution initialised"); cell_t cell; Thread *cell_thread; Domain *subdomain; int phase_domain_index; //Initialisation of heater layer sub_domain_loop(subdomain, domain1, phase_domain_index) { if(DOMAIN_ID(subdomain) == 2) { thread_loop_c (cell_thread,subdomain) { begin_c_loop_all (cell,cell_thread) { real arr[ND_ND]; C_CENTROID(arr,cell,cell_thread); if (sqrt(ND_SUM(pow(arr[0],2),pow(arr[1],2), pow(arr[2],2)))<=0.00000002) { C_VOF (cell, cell_thread) = 0. ; C_P(cell, cell_thread)= 5846400; } else { C_VOF (cell, cell_thread) = 1. ; } } end_c_loop_all (cell,cell_thread); } } } } When I am running the calculation I am getting this error, but there is no error when I am patching it without udf by creating a region. I want this patching operation to be done via udf, so I can generate new bubbles after every time step in a specific pattern. (I will be using EXECUTE_AT_END for that ). I would be grateful if you can help me sir.

Which model of ANSYS is this that contains ICE

Hi, can you suggest how can I simulate the moisture transport from grains to air? Thanks.

Hello Shavan Technology, I'm sorry to bother you, but could I possibly get the UDF code you used? I desperately need the UDF code to simulate the phenomena caused by laser welding. Could you please help me just this once?

The file shared in the description does not exist. Can you please re-upload the file?

Dr Shavan you are genius..

anyone pls tell how to open the file in discription on workbench

hello can you send me the geometry and UDF please

hello sir I am working on coriolis flow meter simulation project . My doubt is how to connect fluent with modal analysis and harmonic analysis

how to know drag coeffcient for 6DOF? in every pitch, roll, yaw, heave, sway, surge??

Dear sir, can we obtain/calculate film thickness as a result of this simulation? If the answer is yes, could your explain how to do it?

How to provide x tends to infinite and y tends to infinite bc on a rectangular fluid domain using fluent sit

Hi, thanks for the great tutorial. Unfortunately when I'm setting the Wall lubrification model to Tomiyama et al I'm getting "A valid 'turbulent dispersion coefficient' (burns-et-al or lopez-de-bertodano) must be set for the appropriate phase-pair when selecting the tomiyama-et-al wall lubrication model." Do you or sombody else have any tips on how to solve this? It would be really really appreciated!

Can you we use bussenique approximation for hydrogen if hydrogen entering into a chamber with heater. To calculate the thermal convection of hydrogen from cold junction to hot junction?

Can you make a video water electrostatic spray through micro nozzle. Water breaking under high voltage?

Hey, Thank you for the informative video. I would to know how we add solid material into the mixture template or how to take solid material into account during crystallization?

Nice explanation... thank you sir ..💐

Nice work

Nice explanation 👏👏

Bro good example and globalwarm

Great Video， BYW I cannot open your google drive at all. Could you please share it again?

why I can't calculate ,it shows that Divergence detected in AMG solver: pressure coupled Divergence detected in AMG solver: k Divergence detected in AMG solver: epsilon Divergence detected in AMG solver: temperature

have you done a pitting corrosion example on ANSYS fluent? How would I do this?

thank you

helpful❤

the link which you provided is not opening sir can you please give me an other one

Can I get your mail id to contact you I have few questions

Can I get your mail id to contact you I have few questions

can u tell me the units of the specific heat in the UDF

Sir, kindly perform an simulation of moving hull with variable speed and correspondingly obtaining hull drag, sea keeping etc results

Great help! Thank U sincerely!

Hello, can you please tell me how the position of node was related to the corrosion? I mean what was the mathematical basis? Is it the size of node(Area, volume,etc) related to the size of eroded molecules? Also thanks a lot for such a detailed video.

hi can i change the value off momentum at 9m 53 s from 0.5 to 0.2 whithout any problem becose i had a good converged contiuity whith this value 0.2

hey can u show how to make that model

Thank u!

how to write udf code for heat flux can you put one video

-1e6 pa ???

RESPECT BROTHER🤖

Not able to get results even I am doing the same thing as guided, is there any additional things to do with simulation

Keep up the good work Can you please email the UDF code that u use for this tutorial

Can you provide the udf for this tutorial.

Would you please inform me that in a 6 dof wave-structure interaction, should I preserve the tool bodies in Boolean operation or not? I think I have a similar project

Hello bro , I Would like to contact you , can you provide details
