【已解决】关于书中第六章例题（RPlug反应器严格模型）的问题
本帖最后由 方林勇 于 2019-7-22 09:19 编辑各位马友好：我在做本书第六章的模拟例题时，输入完组分后，进行分析时，提示如下问题：
STRUCTURE FOR COMPONENT CH3COCH3 HAS NOT BEEN DEFINED.
PCES CANNOT USE GROUP-CONTRIBUTION METHODS TO ESTIMATE MISSING PROPERTIES
USE THE STRUCTURES PARAGRAPH TO DEFINE STRUCTURES OF THIS COMPONENT.
后面进行RPlug流程模拟时，不能完成收敛，还请各位高手看看咋回事。
Block: PFR Model: RPLUG
* WARNING
TOTAL FLOW IS ZERO
**ERROR
RPLUG EXITED BECAUSE INTEGRATION FAILED. INDEX = (-3)
PROBABLE CAUSE IS INCORRECT KINETICS. CHECK RATE-CON
PARAMETERS AND MOLAR VOLUME CALCULATIONS.
*** SEVERE ERROR
FORTRAN DIVIDE BY ZERO ENCOUNTERED.
**ERROR
BLOCK PFR IS NOT IN MASS BALANCE:
MASS INLET FLOW = 0.21805556E+01, MASS OUTLET FLOW = 0.00000000E+00
ABSOLUTE DIFFERENCE = 0.21805556E+01
CHECK INTEGRATION TOLERANCE AND STOICHIOMETRY OR MOLECULAR WEIGHTS
问题已经解决：原来是活化能E的单位搞错了。应该是kj/kmol,我输入成了kj/mol.
真是细节决定成败。

就是的，还折腾我好几天。眼睛都看花了
