Disable function that stops the simulation at tower strike

Hi,

I do not want that FAST is abording the simulation when a tower strike happens. It should complete the simulation.

In which files are which changes are necessary? I searched for “tower strike” in the files and only found it in Aerodyn.f90 and AeroSubs.f90

I hope someone can help me!

Best regards
Kemal

Hi Kemal,

It is the following code in AeroDyn.f90 that is causing FAST to abort upon the tower strike:

if ( TwrClrnc <= 0.0_ReKi ) then call SetErrStat(ErrID_Fatal, "Tower strike.", ErrStat, ErrMsg, RoutineName) end if
You could change ErrID_Fatal to ErrID_Warn and recompile to issue a warning that will not result in the simulation aborting. Of course, the simulation may not be realistic during the tower strike because FAST does not model the impact forcing.

Best regards,
