the direction-dependent properties of objects, such as drag and added mass coefficients, moments of inertia, etc.the coordinates of points which move with the object, such as the vertices of a vessel or the connection point of an object connected to a buoy OrcaFlex uses a number of frames of reference, each of which consists of a reference origin and a set of axes directions, to represent different coordinate.0101 - Alabama East 0102 - Alabama West 0201 - Arizona East 0202 - Arizona Central 0203 - Arizona West 0301 - Arkansas North 0302 - Arkansas. Type in the zone number or select from the list. View the results on this web page or fly there on Google Earth. to convert from the output coordinate system at 0,0,0 to the cg. Convert Latitude and Longitude to State Plane. The most common object-relative items are Now that the latest version of OrcaFlex (11.0) includes a BEM solver (OrcaWave). positions of objects, for example the position of the vessel is defined by giving the global coordinates of the vessel origin $V$.data defining the sea, such as the mean sea surface $Z$ coordinate and the current and wave directions.This enables you to see the local axes and check that they are as wanted.ĭata and results are usually given relative to the global axes, including You can ask OrcaFlex to draw the local axes on the 3D view. The standard import process is then carried out automatically to populate the hydrodynamic data for the newly created vessel types. The reference origin is the global origin and $G\urm$ etc. The vessels are placed in the coordinate system defined in the OrcaWave file (with the global origins of the OrcaWave and OrcaFlex coordinate systems assumed to be coincident).
Orcaflex coordinate conversion how to#
I will also show you how to get the correct angle by plotting the graph. OrcaFlex uses a number of frames of reference, each of which consists of a reference origin and a set of axes directions, to represent different coordinate systems.įirstly, we have one global frame of reference which we denote $\GXYZ$. In this video you will learn how to convert Cartesian coordinate to Polar coordinate.
