Dear Jason,

Could I know how can I generate DLC 1.4 in turbsim? or when I use the IECwind to generate this DLC 1.4 (extreme coherent gust with direction change), it says "this app can't run on your PC". Could you please suggest me on this.

Thanks and regards,

Dear Jason, I have query regarding the calculation of LUlt in MLife. I have calculated the LUlt by calculating the maximum loads or moments(Interface and mudline) based on 10 load cases in MExtrermes and multiplying this value by factor of 5 to get the LUlt. Is this the correct way of finding out th...

Dear Jason,

Could I know what does "Gage" here refers to? what type of sensor (accelerometer?).

Thanks,

Dear Jason,

Thanks for your reply.

Could I know how I can normalize in terms of sign by getting the output in similar s-s and f-a directions.

Thanks,
Satish J

Dear Jason,

Thanks for your reply.

I will try it and let you know if anything comes up.

Thanks,
Satish J

Dear Jason,

Thanks for your reply.

Could I know where might be wrong as I am getting the different direction mode shapes (1st s-s and f-a) when I considered from the mudline. I have attached the plots of both modes for both cases (modeshapes from mudline and interface level).

Thanks,
Satish J

Dear Jason, Thanks for your reply. 1. Is it correct input file(attached file - BModes_ip.rtf) if I want to get the modesahpes from the mudline and considering rigid foundation. I have considered hub_conn to 1 and hydro_M, hydro_K and mooring_K to zero matrix. 2. If I want to consider the soil model ...

Dear Jason, Thanks for your reply. It is working, thanks! I am getting following error when run the tests in the cert folder. ======= Test_03 ======= Running MExtremes (v1.01.00a-gjh, 20-Oct-2015) Reading ".\Data\DLC2.3_1.out" (1.409390 MB). Rows=1201, Cols=133 Done Reading ".\Data\DL...

Dear Jason,

Thanks for your reply.

Got the solution by reducing the time step, thanks!

Thanks,

Dear Jason, Thanks for your reply. I changed the diameter which it was in mm before (It was my mistake), thanks for that. After changing the diameter to meter, I am getting the following error.

Dear Jason,

Thanks for your reply.

So no need to consider the mass and stiffness matrix from subdyn to BModes right (that means zero in hydro_K and hydro_M), if we are considering both tower and monopile in BModes as above.

Thanks,
Satish J

Dear Jason,

Thanks for your reply.

Actually, I wanted to generate the modeshapes from mudline, so any other option in fast itself or BModes that I can get from mudline. Could you please suggest me on this.

Thanks,
Satish J
