Journal file UDF

p.1 · November 27, 2020, 16:16

Hi, there's a way to write a journal file for compiling a UDF (without hooking the function), run calculate for one time step, hooking the function and run calculate for other time steps?

Yes.
Use the TUI to find out which commands you need to use. Honestly, it's very annoying to do (everything has to be 100% correct to work), but it can be done, I have done similar things before.

I can not give concrete code, I'm sorry.

Where I can find the commands I have to use?

Press enter in the TUI, you get a menu with options. Think logically which submenu is most likely to have what you want, and continue from there.

Code:

(ti-menu-load-string (format #f "define user-defined compiled-functions compile? name_of_my_udf_library yes my_udf_source.c \n \n " ))
(ti-menu-load-string (format #f "solve initialize initialize-flow"))
(ti-menu-load-string (format #f "solve set t-s 1"))  ;;;timestep size 1 sec
(ti-menu-load-string (format #f "solve d-t-i 1 30"))  ;;;make 1 time step with 30 iterations inside
(ti-menu-load-string (format #f "define user-defined compiled-functions load name_of_my_udf_library" ))
(ti-menu-load-string (format #f "define user-defined function-hooks adjust  \"my_adjust_tebha::name_of_my_udf_library\" \n" ))
(ti-menu-load-string (format #f "solve set t-s 10"))  ;;;timestep size 10 sec
(ti-menu-load-string (format #f "solve d-t-i 100 30"))  ;;;make 100 time step with 30 iterations inside
