Data format:
A single line comprising 13 values
NGAUSSF NGAUSSK ITYPINV EPS_EFFORT ITSO ILA O1 O2 O3 IWS IINT IOPC IMO2
Status :
Optional
Purpose :
To define the number of integration points and the type of storage for the matrix
Details :
| Parameter | Description |
|---|---|
| NGAUSSF | Number of Gauss points for the numerical integration of the external loads on beam and bar elements. Allowable values are : 2,3,4,10. Default value is 3 . |
| NGAUSSK | Not used in this version |
| ITYPINV | Definition of the numerical scheme for the matrix inversion 0 value by default . Matrix band storage with constant stiffness correction term 1 Matrix band storage only 2 Matrix profile storage (recommended for contact problems) 3 Matrix profile storage with constant stiffness correction term |
| EPS_EFFORT | percentage of the effort at the surface. From a depth Zmax, wave effort are not any more calculated. Zmax is equal to: $ Z_{reg} = \frac{g \ln \epsilon}{4 \pi2}T2 $ where \(g\) is the gravity acceleration and T is the period of the wave (for irregular wave it is the maximum period) |
| ITSO | = 0 (default). = 1: line search is activated to optimize displacement (obsolete) |
| ILA | = 0 (default). =1 : Updated Lagrangian formulation (obsolete) |
| O1 / O2 / O3 | =0 (obsolete) |
| IWS | = 0 (default). =1, wave stretching is deactivated |
| IINT | To define the spline order for interpolation of motion(see GMOVE2, GMOVE3). Must be larger than 5. |
| IOPC | = 0 (default); = 1 : Convergence criteria and displacements increments are local; = 2 : Convergence criteria is global and displacements increments is local; = 3 : Convergence criteria is local and displacements increments is global (recommended to use *OPT_CONV instead) |
| IMO2 | = 0 (default); = 1: Drag force is based on the norm of the total velocity multiplied by the normal (resp.tangential) velocity instead of on the norm of the normal (resp.tangential) velocity multiplied by the normal (resp. tangential velocity) |
Note
Numerical integration of the hydro-static and -dynamic forces on elements cutting the water free surface is performed with NGAUSSF points along the wetted length only.
