我最近也遇到了类似的问题,真空收敛没问题,但是一上溶剂模型就给出“ PCMQM: There is more than one cavity, setting IComp=0. Inv3: Mode=3 IEnd= 39044.”,然后就不继续往下算了。在网上找到了一个回答,但是似乎还是不能解决问题:
This is telling you that there is more than one cavity in the "solvent" model. Essentially, the PCM model is sensing that there are two distinct entities rather than a continuous system. Given that you are optimizing a vdW type complex, this message makes sense.
The minimum you obtain with PCM should be different from the non-PCM (i.e. gas phase) optimization as the local environment is, by definition, different in that case.
