Hello Chris. If you want the software installation installation package, it is available on the FVS website (https://www.fs.usda.gov/fvs/index.shtml). The FVS source code is now in a GitHub repository with the public version here (https://github.com/USDAForestService/ForestVegetationSimulator)

Good morning Erin, Thank you for providing your data and keywords for my testing. The modification I have placed in the code does alleviate the underflow error and the run did crash for me as well using the current release FVSop. The way the timing for the run is set up in the keyword file is incorrect and I am actually a little surprised that it did not trigger an error, but the CycleAt keywords make FVS reassign number of cycles and cycle lengths overriding the error of assigning a single cycle...

Thank you, Erin. I got your TestRun.zip.

Hello Erin, Regarding the FVS ticket #64 with the underflow error at 16 cycles. I have added code for the FVSop variant, but I have no data or keywords that would cause that error. I would like to process your failing run with current release and confirm the error happens for me and then test the new code to make sure the error has been averted. Can you provide the keyword file and data that caused the crash? Thank you Lance From: tickets@open-fvs.p.re.sourceforge.net tickets@open-fvs.p.re.sourceforge.net...
