Hi,

I am trying to run a UDF for a dynamci mehs model on a HPC. I used these two lines to complie and load the udf:

define/user-defined/compiled-functions compile "libudf" yes "udf.c" ""

define/user-defined/compiled-functions load "udf.c"

But I keep getting this error:
Auto-compilation skipped. Could not find "libudf" or input files for creating "libudf" library

 

Any thoughts?

Hello,

is the udf.c file located in the working directory?

Yes my .sh code copies the udf.c to the directory. It created a libudf file with the udf.c in it. 

I created a libudf file in the directory manually before submitting the job bu then the temperature I patch to a part disappears. What is the TUI to patch this:

 

Thanks

I am using this command: 

followup:

/solve/patch () (part-steel_tube) temperature 30

but getting this error:

> /solve/patch () (part-steel_tube)
Error: eval: unbound variable
Error Object: part-steel_tube
 temperature 30

Try running the command locally one step at a time. I think you need to move the brackets. 

/solve/patch () (part-steel_tube) () temperature 30

I tried locally on step at a time and this worked: 
/solve/patch () temperature 30

 

Nevertheless, when I monitor the temperature of the part-steel_tube, it is giving a wierd value:

 

Any thoughts?

 

Thanks,

The output is going to be in Kelvin - all the Fluent UDFs use and monitors tend to return SI units.
