Hello everyone,

I am working on advanced nuclear power plantas, so I have been trying to create Pb and Na as compounds to perform thermodynamic analysis of liquid metal fast reactors. I have used the CAS number of each component, but an error window is displayed with the following message "one or more errors occured". Afterward I tryed import them from thermo python librarie but with the same result "error",

Any suggestion to add them to Dwsim? or any tutorial useful to recomend?

Best regards,
Luis
