aspen出现问题

请问一下，为什么运行之后就出现错误（附件中有aspen流程）Block: P2       Model: PUMP**ERROR WHILE GENERATING RESULTS FOR UNIT OPERATIONS BLOCK: "P2" (MODEL:
      "PUMP")
      BUBBLE POINT CALCULATIONS CANNOT BE PERFORMED BECAUSE THE SPECIFIED

      FAILED TO CONVERGE. NPSH AVAILABLE IS UNRELIABLE.

不收敛啊，好像不是泵的问题，是三进三出换热器的问题！

好复杂啊，不懂

应该是条件有问题

应该是一定压力下，泵的进料温度的问题吧，可以试试
