Thanks David. The remeshing worked but there were still a few triangles/tetras. How do I convert these to quads/hexas?<div><br></div><div>Ted</div><div><br></div><div><div><br><div class="gmail_quote">On 27 November 2010 13:51, David Colignon <span dir="ltr"><<a href="mailto:David.Colignon@ulg.ac.be">David.Colignon@ulg.ac.be</a>></span> wrote:<br>

read carefully the output:<br>

<br>
you forgot the ";" after Mesh.RemeshAlgorithm=1<br>
so you get a syntax error on the next line: Recombine...<br>

I tried used the following geo file to remesh my STL file using quads/hexas:<br>
<br>
Mesh.CharacteristicLengthFactor=0.25;<br>
Merge "mesh.stl";<br>
CreateTopology;<br>
<br>
Compound Surface(200)={1};<br>
<br>
Mesh.RemeshAlgorithm=1<br>
<br>
Recombine Surface {200};<br>
Physical Surface("newSurfaceMesh")={200};<br>
<br>
but I get this error even after adding 'Mesh.RemeshAlgorithm=1':<br>
