How to implement HydroStatic Pressure in Ansys Fluent | step by step

In a lot of projects, you should insert hydrostatic pressure into your problem but you don't know how to do this. Some of them are in a long container or at sea/coastal problems.
Hence this video is made for you to solve your problem as easily as possible.

I am wondering that we should define hydrostatic pressure formula as udf file for such a powerful CFD software. isnt there any way to achieve hydrostatic pressure from fluent without using udf file? thanks for your tutorial video and your fluent English accent.

[@libinabraham5644]

yes..u can define operating density as zero and fluent will calculate the hydrostatic pressure hence buoyancy

[@amirtaghizadeh8204]

Thank you for the video. Is it possible for you to send us the code itself too?....i need to include the hydrostatic pressure for my pressure inlet and i think i need the same udf code too.

[@luisaciriaco5338]

I would appreciate if you could send me the code either! I also need to include the hydrostatic pressure in a project!

[@ebnenabi6615]

That was great! Is it possible to analyze the Buoyancy forces in Ansys Fluent?

[@shivamsalokhe2954]

Set your operating density 0 in operating conditions and make your reference density equals to your fluid.

Hello sir, may I know why is it 145000-10000*y ? what does the 10000 represent? is it suppose to be the density of the water?

[@mehmetdelikan4687]

Thank you for this tutorial. I need this code at my dissertation project. Can you share your code with me ?

I am trying to simulate the upward wicking in the porous media. I have defined a capillary forces at interface that pulls interface in upward direction against gravity but I am not able to include the hydrostatic or gravitational forces that balances the capillary forces. Can you suggest something about it??

[@shivamsalokhe2954]

Also, in UDF that you showed, how did you select the value of absolute pressure value to be 145000?

[@messy8852]

At the beginning of the video, I set the height of the domain as 14.5 m. Hence the pressure of the lower place is density*gravity*height = 145000

In which section you can't include hydrostatic pressure? At first iteration, second iteration and above, or whole project.

[@shivamsalokhe2954]

@@messy8852 Thanks for the reply. I was able to figure out the problem. Since I am using vof model, hydrostatic pressure can be included simply by specifying the operating density.

what is file named "water_inlet.c" ?
