Forum: Fluent UDF and Scheme Programming May 24, 2016, 12:40

The problem has been solved. It appears that the mass transfer rate was so small that the simulation needed to be run for an extremely long time to achieve a measurable ...

I get very small values of ml_g being repeated many times. Yes it seems that the UDF is working. It is strange though that I am not observing any transfer from the liquid to the gas phase (it is a...

That solved the problem of allowing me to hook the compiled UDF to the phase interactions panel. But, when I run the compiled UDF, there is no mass transfer occurring (it appears that...

I tried using the simplified code that you suggested, Pak. There are no error messages during building or loading the UDF, until I select "user defined" option from the phase interactions panel and...

To summarise: In interpreted mode: Interprets UDF fine, but produces a segmentation error when I try to initialise. In compiled mode: Builds and loads fine, but isnt visible on phase...

I'd expect the code without the loop to work, which is why i am beginning to think the problem is due to a problem with compilation.

I've noticed something strange that I hadn't realised before. When trying to compile the UDF, it builds and loads without any errors. However, when I try to hook the UDF in the phase interactions...

I tried changing the position of return (m_lg) but it didnt work. I also tried no loop at all but it didnt work. Without a loop it returns a cortex error at initialisation

Yes it looks like you are correct according to the UDF manual. So, I changed it to THREAD_ID(thread)= 2 as the cell zone ID number of the fluid is 2. But this still didn't fix the problem....

Replies: 16 Interfacial species transport UDF in Eulerian model Views: 2,484 Posted By richard222 Interfacial species transport UDF in Eulerian model I am simulating species transport in a 2 phase vapor-liquid bubble column using the Eulerian framework. This UDF is designed to calculate the mass transfer rate of one species from the primary phase...
