Ashes 3.16

• Validation/verification report published online 
• Mass, shear and elastic center offsets for blades 
• Cross-section widget for blades 
• IEA 15-MW wind turbine provided 
• Precompiled ROSCO controller provided
• Parameters can be passed on to python controllers 
• Improvements in error handling for input files

2 Known issues and workarounds

• Initial pitch has been disabled for this version. To have a structural pitch, use the pitch actuators and the PID controller for the demanded pitch scheme 
• Exporting and importing the floater makes mooring lines disappear. The suggested workaround is to add the mooring lines with the 'Configure moorings' action button
  
• The DTU 10-MW RNA saved in the RNA database has a wrong gearbox ratio: it should be 50 instead of 97
  
• The IEA 15-MW RNA saved in the RNA database has a wrong nacelle mass: it should be 630 888 kg instead of 360 888 kg
  

3 Bugs fixed

• Importing floater created two tubular towers 
• Element with unspecified geometry had Area in vbox info 
• Incorrect error message in batch when path to controller is wrong 
• Structure was re-created when importing support sections in batch 
• Blade structure was not saved with the model 
• Point mass at the Nacelle Center of Mass node was not shown 
• Hydro coefficients were applied below sea bed
