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

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.
