关于变换模拟中出现的警告问题

方林勇 · 发表于 1970-1-1 08:00:00

最近因工作需要，模拟变换装置的流程，在模拟计算中出现如下警告，还请大侠们，看看是什么意思，代码如下：

==================================================================
1、WARNING IN PHYSICAL PROPERTY SYSTEM IN THE "PROP-REPLACE" PARAGRAPH WHICH
   BEGINS ON LINE 468
   USING PROP-REPLACE WITHOUT A BASE PROPERTY-METHOD IS NOT RECOMMENDED
   BECAUSE ALL PROPERTY METHODS INCLUDING SYSOP0 & STEAM TABLES WILL BE
   CHANGED. PLEASE SPECIFY A BASE PROPERTY-METHOD.
2、WARNING IN PHYSICAL PROPERTY SYSTEM
   PARAMETER FREEZEPT/ELEMENT  1 (DATA SET 1)
   UPPER BOUND VIOLATED FOR COMPONENT C
   VALUE = 4300.0 , UPPER BOUND = 4000.0

3、  WARNING WHILE CHECKING INPUT SPECIFICATIONS
   INCONSISTENT PROPERTIES DETECTED FOR 4 STREAMS
4、WARNING
   AT LEAST ONE FEED HAS ZERO FLOW
   BLOCK BYPASSED
5、* WARNING WHILE GENERATING RESULTS FOR UNIT OPERATIONS BLOCK: "E2002"
   (MODEL: "HEATX")
   CALCULATED FEED TEMPERATURE FOR THE HOT SIDE (7.2763946D+02)
   IS INCONSISTENT WITH ITS INLET STREAM VALUE (7.2910657D+02)
   PROBABLE CAUSE: LOOSE FLASH TOLERANCE, OR UPSTREAM BLOCK WITH DIFFERENT
   NPHASE OR PROP SET. THE CALCULATED VALUE WILL BE USED IN CALCULATIONS

  * WARNING WHILE GENERATING RESULTS FOR UNIT OPERATIONS BLOCK: "E2002"
   (MODEL: "HEATX")
   CALCULATED FEED TEMPERATURE FOR THE COLD SIDE (4.6437560D+02)
   IS INCONSISTENT WITH ITS INLET STREAM VALUE (4.6314876D+02)
   PROBABLE CAUSE: LOOSE FLASH TOLERANCE, OR UPSTREAM BLOCK WITH DIFFERENT
   NPHASE OR PROP SET. THE CALCULATED VALUE WILL BE USED IN CALCULATIONS

期待高手解答！

个人觉得这个流程设置出现了问题 4、WARNING
AT LEAST ONE FEED HAS ZERO FLOW
BLOCK BYPASSED
然后导致了一系列的问题。。。如果方便请贴出模拟文件

应该是循环没设初值吧。

来看看
我也在做变换模拟
