inputs.validation.WECSim.normalizeBEM(hydro)

Function normalizeBEM()

Parameters:

hydro – function from WECSim

Returns:

function from WECSim

Normalizes BEM hydrodynamic coefficients in the same manner that WAMIT outputs are normalized. Specifically, the linear restoring stiffness is normalized as \(C_{i,j}/(\rho g)\); added mass is normalized as \(A_{i,j}/\rho\); radiation damping is normalized as \(B_{i,j}/(\rho \omega)\); and, exciting forces are normalized as \(X_i/(\rho g)\). And, if necessary, sort data according to ascending frequency.

This function is not called directly by the user; it is automatically implemented within the readWAMIT(), readCAPYTAINE, readNEMOH, and readAQWA functions.

Parameters

hydro[1 x 1] struct

Structure of hydro data that will be normalized and sorted depending on the value of hydro.code

Returns

hydro[1 x 1] struct

Normalized hydro data

inputs.validation.WECSim.myWecSimFcn(imcr, mcr, pctDir, totalNumOfWorkers, X, p)

Function wecSimFcn

Parameters:

  • imcr – imcr

  • mcr – mcr

  • pctDir – pctDir

  • totalNumOfWorkers – totalNumOfWorkers

  • X – Design variable vector

  • p – Parameter struct

Returns:

output

wecSimFcn WEC-Sim from function executable+

inputs.validation.WECSim.readWAMIT(hydro, filename, exCoeff)

Function readWAMIT()

Parameters:

  • hydro – function from WECSim

  • filename – filename

  • exCoeff – exCoeff

Returns:

function from WECSim

Reads data from a WAMIT output file.

If generalized body modes are used, the output directory must also include the *.cfg, *.mmx, and *.hst files. If simu.nonlinearHydro = 3 will be used, the output directory must also include the *.3fk and *.3sc files.

See WEC-Sim/examples/BEMIO/WAMIT for examples of usage.

Parameters

hydrostruct

Structure of hydro data that WAMIT input data will be appended to

filenamestring

Path to the WAMIT output file

exCoeffinteger

Flag indicating the type of excitation force coefficients to read, ‘diffraction’ (default), ‘haskind’, or ‘rao’

Returns

hydrostruct

Structure of hydro data with WAMIT data appended
