关于变换模拟中出现的警告问题

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/ELEMENT1 (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

===============================================================

很复杂啊，不明白

此类问题太高端。

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
