I want to access the level-set function within a UDF for an interface. Please tell me if there an any macro for that.

Thank you.

Is there any way of accessing the value of a global maximum value in the domain using a UDF in fluent?

Thank you in advance.

Fluent / Is there any UDF to access inter-phase mass transfer rate
« on: September 24, 2020, 04:46:00 PM »
I need to access the inter-phase mass transfer rate using a UDF in Fluent for further processing. Is there any macro or other method in fluent to access that?

Thank you in advance.

Hi,

I need to access the level-set function in Fluent using the UDF. Is there any function for this?

Thank you.

How can I get time-dependend information about aerodynamic forces and moments, like lift, drag, euler angle, CG, of moving and stationary walls in FLUENT?

Thanks.

You can convert the equation:
vθ = vx cos θ + vy sin θ

into Cartesian coordinate.
x = r cos θ
y = r sin θ

I get the following when I load the case and data file:

999999 (..\src\mpsystem.c@1149): mpt_read: failed: errno = 10054

999999: mpt_read: error: read failed trying to read 4 bytes: No such file or directory
MPI Application rank 0 exited before MPI_Finalize() with status -1073741819
 The Parallel FLUENT process could not be started.


Can any one give suggestion?

Thanks.

Fluent / VOF to model draining tank, swirling fluid, vortex?
« on: May 13, 2012, 11:16:43 AM »
Hi,

It is possible to model a draining tank filled with a swirling liquid, and to capture the vortex that forms at the drain. The goal is to pinpoint the time at which the first gas reaches the drain.

Please help.

Thanks.
