Hi,
I am relatively new to ICEM and am wondering if anyone can figure out why I cannot successfully build the topology of an STL file I import into ICEM CFD.

Within ICEM CFD, I do the following:
File -> Import Geometry -> Faceted -> STL

Geometry (tab) -> Repair Geometry -> Build Diagnostic Topology
using a Tolerance of 0.001

I apply this, and get the errors: 'Couldn't find curve point to move'
And "curve _______ edge not in surface _____"
Followed by the program getting hung up.

The STL file, even compressed, is too large to upload. I create the STL file in Mathematica. The code used to generate the 3-D shape is:

Code:
r=(1-Cos[2 theta]^4)^20 * (1-Sin[phi]^4)^20;

g=ParametricPlot3D[{r*Sin[theta]Cos[phi],r*Sin[theta]Sin[phi],r*Cos[theta]},{theta,0,2Pi},{phi,0,2Pi},PlotRange->{{-1,1},{-1,1},{-1,1}},PlotPoints->50];

SetDirectory[NotebookDirectory[]]
Export["fourlobe.stl",g]
I have used this approach before for other 3d shapes successfully.

Thanks,
Joe
