Error in connectivity

[Monica_Gao]

Dear Professor David,
    When I calculate the Rosenbluth Weight of water in a box with a size of 30 * 30 * 30, it fails and shows "No atoms can be grown, check the connectivity of your molecule", Could you tell me how to sovle this problem? It happends in both the water defination files defined by me and the original file in RASPA.

The file defined by me:

Another thing it that, some articles published in journals involves multi-component adsorption, but I tried yestaday, but it failed with an error, so could you please tell me how to work it out?

I will be very grateful if you give me some instructions and advices, thank you very much.
Best Regard,
Monica Gao.

Dear professor David,
  I have found the mistakes in both water definition files, so if you read this problem please ignore the first question and to the second question.
  Could you please give me some advices to calculate multi-component adsorption with at least three components?
  I am very grateful and look forward to your answer.

Best regard.
Monica, Gao

Check the manual and examples. There are explicit examples for mixtures and adsorption mixtures,
for example:
examples/Basic/MC_BinaryMixture_in_Box
examples/Non-Basic/Adsorption_of_Binary_mixture_CO2_CH4_in_IRMOF-1

Dear professor David,
Thank you very much. And Merry Chrisma  ;D
