Re: udf-time dependant temp boundary
You need to use the user subroutine BCDEFW. First enable this in the Define Boundary menu for any wall requiring temp controlled by the program.

Then write BCDEFW to the ufile sub-directory, and then go and edit it and add whatever time dependant code you want.

Re: time dependant temp boundary
i also have a similar problem w r to defining a time variant temp boundary condition. i tried using the field functions (condition statement) but the s ware while iterating does not seem to take the function and does not follow the defined profile and the temp just keeps increasing

All times are GMT -4. The time now is 02:34.
