"Allocating Space" error in running Fast

Wind & Water Computer-Aided Engineering Software Tools

Hello!

Recently I faced a problem in running FAST.
I built a model for an offshore wind turbine. I also used FAST V8.08. It used to work properly, however recently I got this error.

When I use FAST_Win32 I face:
"
Message from HydroDyn_Init:
HydroDyn_Init: Error allocating space for the distributed inertial forces/moments array.

FAST encountered an error at initialization.
Simulation Error level: FATAL ERROR

Aborting FAST.
"

And also when I use FAST_x64 I face:
"
Message from MAP_Init:
MSQS_Init not available using dummy MAP dll.

MSQS_End not available using dummy MAP dll.
FAST encountered an error at initialization.
Simulation Error level: FATAL ERROR

Aborting FAST.
"

It is worth mentioning that my Windows is a 64-bit one, 10 version (Windows 10).

Please kindly let me know about these two matters:

  1. How can I fix this problem?
  2. As all the files are prepared in FAST V8.08, is it possible to run them using the latest version of FAST? Should I change anything or only use the executable file and MAP file?

Thanks for your time.

The first error indicates that you’re exceeding ~2 GB (it should be a little larger that that on your 64-bit PC because it knows about “large” addresses, but it is still limited). If it was working before, you’ve probably changed something in the model that makes it use more memory–different discretization, larger wind files, larger simulation length (with waves), etc.

If you update to the latest version of FAST, you can use the 64-bit version and run MAP (I think it was version 8.10 where we got a working 64-bit version of the MAP dll). You’ll have to update your input files, too. There is some documentation on what changed and how you can update your input files to the latest version on the FAST 8 website.
