Hi,
I have a Unisim connector and I am trying to parse a Unisim model with several flowsheets. It works when the model only have one flowsheet, but not when it has several. Is it possible to work with Unisim models containing several flowsheets?

Just browsing through Honeywell API docs.
There is a property called “fsname” - USD Flowsheet name.
Maybe it should be incorporated into the Cognite UniSim Connector?

@belaz19 ​@Marthe do we have any logs or error messages that we can see to get more context out of this.
