Hello,

I am trying to create a 1 hour wind file using TurbSim with the following input file and am getting an error allocating 1396MB for the velocity array.

Is this related to the allocation in the fortran code or the limits of a windows 32bit system with 3.16GB RAM? TurbSim managed a 30minute simulation although it was some hours…

Thanks,

Rebecca
