The question is in fact that does the local coordinate system of the analytical surface have to be cartesian system.
Any export here having experience upon this can help me out?
i am trying to generate an analytical surface for contact problem. According to the keyword reference manual, the coordinates of there points, a,b,c, should be provided to establish a local coordinate system. Then, define a curve (straight or curved) in the local x-y plane. The curve on the...
If we want to consider VIV issues for submerged structures, we need to calculate the in-line and cross-flow frequencies of the pipeline/jumper/riser. Caesar II have mode analysis and can provide the natural frequencies of the structure.
As we learnt from classical vibration mechanics, the...
