Thank you very much for your help, but I still have a question: What is the difference between TYPE=PIPE ENTRANCE and TYPE=PIPE INOUT? Why do I find it in some of your inp format files (for example, pipe.inp and pipe2.inp), some apply TYPE = PIPE ENTRANCE and TYPE = PIPE INOUT, while some files only have TYPE = PIPE INOUT. So how do I determine how to quote this? Thank you again
