Running CSP simulation with API won't run: set year and month. was created by ampodgorski

After clicking Generate Code for Python 3 and running the simulation as a test for using the SDK with CSP Molten Tower, an error message is developed:

S_decode ==> Please fix the year: 0 [1950-2050]
S_decode ==> Please fix the day-of-year: 0

How can the year / day-of-year be set? I cannot find an answer in the documentation and I have tried setting it using the normal ssc.data_set_number() method.

Thanks,
Adam

Dear Adam,

You can ignore those two errors.

This is an issue with some of the power tower model's underlying code, specifically in the S_decode function in solpos.cpp , which writes a series of messages to

stderr

. The function reports the two errors you mention even when the weather file is valid, so that is a bug in the code that we will fix.

Depending on how you are executing your Python code, you may or may not see the

stderr

messages. If you are seeing the messages and want to suppress them, you can use the following from the command line to redirect the messages, assuming your Python code is in a file named "untitled.py":

python untitled.py 2> out

Best regards,
Paul.
