Hi Oliver,
t = 1.4; al = Pi/12; umin = 1; umax = 13; vmin = 3; vmax = 5;rho =
Sqrt[u^2 + v^2]; th[u_, v_, gt_] := ArcTan[u Cos[gt] - v Sin[gt], u
Sin[gt] + v Cos[gt]];
RectStrpCone = rho*{Sin[al] Cos[th[u, v, t]/Sin[al]], Sin[al]
Sin[th[u, v, t]/Sin[al]], Cos[al]} ;
ParametricPlot3D[RectStrpCone, {u, umin, umax}, {v, vmin, vmax},
PlotPoints -> {31, 6}, Mesh -> All, MaxRecursion -> 0]
E.g., I define curvilinear coordinated parametric points as above in
Mathematica and after deciding to accept it for further Ansys
geometric Modeling I wish to transfer nodes, keypoints and shell
elements through a Table to Ansys with Mesh Data.
And :) of course, after a common coordinate system is defined,
directly Cutting and Pasting the Mathematica 3-D patch image directly
into Ansys screen... by right click or GUI.. that is my final Graphics
Import (Important) dream ! Anyhow Mathematica can now itself identify
tangents, normals and binormals, useful for defining of load
application along correct directions, to arrest not required DOFs etc.
