模拟中出现下列错误是什么意思? 同样的流程,同样的规定,我又从头到尾重新输入了一遍,将严格塔换为简捷塔后,lng换热器的定义无法与塔冷凝器的热负荷关联,只能与fenske index for section1关联,其它完全一样,但是还是不通, 1 error(s), 5 warning(s), and 0 message(s) detected: ** warning ** solids are present in the flowsheet. unit 8, 'e1e2' - an lng exchanger cannot handle solid-phase components. ** warning ** solids are present in the flowsheet. unit 9, 'lng' - an lng exchanger cannot handle solid-phase components. ** warning ** stream '5'-- the thermodynamic method set for this stream is not the same as the method set for unit 'hp'. ** warning ** stream '8'-- the thermodynamic method set for this stream is not the same as the method set for unit 'e2'. ** warning ** stream '12'-- the thermodynamic method set for this stream is not the same as the method set for unit 'e1'. *** error *** controller unit 13, 'con' variable is invalid because value was not input in unit 'lng'. 具体是什么意思啊? 望高手指教。查看更多
