3D dynamic mesh tutorial
 

Hi people,

I was attempting the 3D adiabatic compression tutorial with dynamic meshing and I haven't got the file cyl3d_new.msh. If anyone can send me the file please it will be greatly appreciated. Thanks.

Hi, I am trying to simulate the 3-D flow dynamics of bubble column (gas-liquid flow using euler-lagrange simulation) using FLUENT. I am filling only half the column with water and trying rest to patch with air.
Could anyone suggest the right way to patch gas-liquid in the bubble column? Also, how do you really model gas-liquid free surface flow in Bubble Column? Thanks.

I appreciate your help.

My problem is similar to the one discussed here. I need to specify the flux of scalars at the boundary. They are neither constant nor are they known before hand.
I followed the procedure suggested by you. I use the define_profile to initialise the flux value to zero and write the zone id and uds id to a file. This is happening.
I then access the corresponding files depending on the thread id, read the values from the files and use F_PROFILE to assign the flux values from stored memory.
I have used solve/set/expert to save the gradients.
When i hook the ADJUST udf and run, fluent shuts down.
What could be the problem?
Thanks in advance

Not using Fluent these days
 

Hi, and thanks for the interest in this thread. I should let you know that I am not an active Fluent user anymore (for 3 years now) and will not be able to respond to further inquiry at present.

Hello,

I want to change UDS boundary value i mean i want to use transient value , you know how can i do this with Define Adjust?

Regards,

Hello,
do you get any information on your problems? My problem is the same as you. Thank you in advanced!

use DEFINE_PROFILE macro

Hello,Alexander
I need to apply the gradient of C_UDSI on the surface, does DEFINE_PROFILE work? I find that the GUI have two options, which is Flux and Value for UDS boundary condition.

Hey guys,

I'm working on something similar, was wondering if maybe you solved yours.

I've got a simple flow problem with:
INLET = Pressure
OUTLET = mass flow rate

at some location I've got a user surface where I can calculate flow velocity.
I want a UDF that can update the mass flow rate at the outlet based on the velocity calculated at the user surface.

Any thoughts? do I need to use the DEFINE_ADJUST macro?
