<div>Hi</div><div><br></div><div>I added Volume and Physical volume to the geo file (see below):</div><div><br></div><div><div>Mesh.CharacteristicLengthFactor=0.25;</div><div>//Mesh.Algorithm3D = 4; //Frontal (4) Delaunay(1)</div>
<div>Mesh.RemeshParametrization=0; //(0) harmonic (1) conformal</div><div>Mesh.RemeshAlgorithm=1;</div><div><br></div><div>Mesh.RecombinationAlgorithm=1;//blossom</div><div>Mesh.RecombineAll=1; //all</div><div><br></div><div>
Mesh.Algorithm=8;//delquad mesher</div><div><br></div><div>Merge "offset_mesh.stl";</div><div>CreateTopology;</div><div><br></div><div>Compound Surface(200)={1};</div><div><br></div><div>//Surface Loop(300)={200};</div>
<div>Volume(301)={300};</div><div><br></div><div>Physical Surface (501)={200};</div><div>Physical Volume(502)={301};</div></div><div>=====</div><div><br></div><div>but I get the error:</div><div><br></div><div><div>Error: The point set is trivial.</div>
<div>Error : Self intersecting surface mesh, computing intersections (this could take a while)</div><div>Error: The point set is trivial.</div><div>Error : Surface mesh is wrong, cannot do the 3D mesh</div></div><div>
===</div><div><br></div><div>I tried it using 'pelvis.stl" and I get the same error. Could someone advise me on how to fix this. It may be a naive and/or easy question but I'd appreciate some help.</div><div>
<br></div>-- <br>Many thanks,<div><br></div><div>Theodore K</div><div><br></div><br>
