Hi,

How can I get the number of faces in a boundary zone to use it in a variable in Fluent?

Thanks.

I want to monitor the location of min/max values, lets say pressure over the duration of a simulation with Ansys Fluent. Can anyone please help?

Thank you.

3
Why is the mass flow rate of a chemical species into the domain not equal to the product of the mass fraction and the bulk mass flow rate?
Help.

What turbulence model should I use to model gas-solid fluidized bed in FLUENT?

Thanks.

5
What is the best way to sample the mass flow rate in a transient run in FLUENT?

I get the following error when I changed my multiphase model from VOF to Eulerian in my case setup. Error:Cell_Function_Values: unrecognized function: velocity magnitude.

I need help please.

Fluent / Modify drag coefficient using Fluent UDF
« on: April 25, 2012, 10:15:30 AM »
I want to modify the drag force on the particle tracked using Lagrangian approach based on the concentration of particles in the cell volume. To get the cell information I need to know which cell the particle is in. I can not figure out how to do this in the DEFINE_DPM_DRAG

Can anyone help me please!

Meshing / GAMBIT - "Identifier Currently Open" Error
« on: April 10, 2012, 10:40:06 AM »
Hi,

While I am working in GAMBIT the program crashes and then when trying to relaunch GAMBIT and open the project with which I was working I receive an error message from GAMBIT:ERROR:IDENTIFIER filename CURRENTLY OPEN.

Please help.

Fluent / How to calculate heat transfer rate within UDF?
« on: February 12, 2012, 12:24:19 PM »
Hi,

Within a FLUENT UDF, how can I calculate the total heat transfer rate (radiative + convective), radiation heat transfer rate, or the absorbed radiation flux on surfaces?

gPROMS / gPROMS - Aspen
« on: February 11, 2012, 02:45:24 PM »
Hi

I am trying to use a CO properties package created in Aspen Plus 2006.5 21.0 in gPROMS. Does anyone have any tutorials on how to do this and/or does anyone know the ThermoSystemProgID of Aspen Plus?

Thanks.

I am tracking the particles using the lagrangian approach. Sometimes the temperature of the particles exceed the temperature of the continuous phase. Sometimes it goes to negative kelvin. The velocity of the particles is also weird. I have coupled the momentum exchange terms in Fluent. Particles momentum and fluid phase momentum is exchanged once per iteration.

What am I doing wrong?
