The shareable fsd file solves so the compositions must transfer properly. The error is not reproduced in the shareable fsd file. My point was that the sub-flow sheet structure is the same. So I will accept your answer that the shareable fsd file would not be useful to you. Thought that I would give it a try since the Custom Units function in this instance.
I unraveled the sub-flow sheets in stages in what follows.
Test 1
moved sub 1 into sub 2 flow sheet
now new sub 2 flow sheet
connected streams
result was same error message as when
subs were two levels deep
see below
error: calculate failed for unit OEA Module System:
Failed to flash internal material: CalcEquilibrium failed:
Failed to wrap v1.0 CalcEquilibrium of type "TP" to v.1.1:
CalcEquilibrium failed: CalcEquilibrium failed: TP flash failed:
composition not set for one or more compounds
Test 2
moved new sub 2 into overall flow sheet
sub 1 & sub 2 are both at top level now
(no Custom Units are employed)
connected streams
No error messages
the flow sheet solved without any assistance
During this effort, I eliminated the Custom Units and successfully solved the flow sheet. I hope someone can help determine the problem(s) with the Custom Unit because I would like to use it but cannot for this flow sheet project. I will try to use the Custom Unit again in the future. Please inform me of any developments. Thanks for the help.
