Hi all, it seems the fluid transient module in AutoPIPE works by calculating the differential pressure in each pipe leg and applying the resulting force in a single direction at the point which experiences the higher pressure first. If you're manually working out the THPs and THLs, does anyone know if you can just apply the individual forces at opposite points in the pipe leg and will AutoPIPE calculate the balancing of these forces correctly or is it better to work out the differential pressure and just have it as a single force at one point in the bend?
Greetings Brody,
Please understand the workflow here. With just a few key pieces of information in the Fluid transient dialog, AutoPIPE will automatically generate the THL and THP files for you with all the necessary information formatted correctly.
THL and THP files are simple text files that are specially formatted for AutoPIPE to read while running an dynamic analysis. If there is any missing information in the file, the program will not update these files with that missing information. Also, if anything is not formatted correctly, the software may use a wrong value in the calculations or present an error message.
Again, THL and THP files are just a text file read by AutoPIPE. That is why it is vitally important when manually creating these files that all the required data is available and formatted correctly. If you want to manually generate your own files, then suggest to use the fluid transient utility, fill in any data on the dialog, press OK button, the software will create all the required files that are formatted correctly, open each file in any word editing program (i.e NotePad++, Uletra Edit, MS Word...etc) use overwrite command to update data as needed,l and save for use in AutoPIPE. Highly recommend to maintain column alignment in these files.
