TurbSim 2.1 simulation time

Hi,

I have cloned openfast from github, from which I have compiled turbsim using intel fortran compiler in visual studio. The compilation process goes through just fine, but I experience that the running times with the generated executable is quite a lot longer than the executable I have downloaded directly on NREL’s website. For a given .inp file the simulation took 250 s vs 30 s. Is this due to some mistake I have done in the compilation or is this behavior expected?

Best regards Pål Sandnes

Dear Pål,

I would not expect that. The TurbSim executable available from the NWTC Information Portal is compiled in release mode in single precision. Perhaps your compiling in debug mode or double precision?

Best regards,

Thank you Jason! Indeed it runs as expected now that I switched to Release configuration in visual studio.

Best regards
Pål
