Running examples with the Seismic module

[Xu.Pengfei]

Dear Jason,

@Jason.Jonkman

To include seismic functionality for an offshore wind turbine atop a monopile, the model should be set up similar to the coupled springs model–e.g., see the platform file named NRELOffshrBsline5MW_Platform_Monopile_CS.dat and the associated tower file named NRELOffshrBsline5MW_Tower_Monopile_CS.dat

Thank you. Is that seismic function can only be considered on apparent fixeity model? I still have some questions about this paragraph you mentioned earlier.I am confused about how to simulate the coupling effect of single pile structure hydrodynamics and seismic functionality. To implement hydrodynamics and seismic functionality coupling, you don’t need to recompile, right? But I still have problems at run time, it will reminder me like this:

I have read the previous related topics: Small angle assumption violated in SUBROUTINE SmllRotTrans()
Simulating OC3 phase II coupled springs in FAST v7, but there is nothing about seismic functionality. Could you give me some guidance and suggestions?
