Hi

I added Volume and Physical volume to the geo file (see below):

Mesh.CharacteristicLengthFactor=0.25;
//Mesh.Algorithm3D = 4; //Frontal (4) Delaunay(1)
Mesh.RemeshParametrization=0; //(0) harmonic (1) conformal
Mesh.RemeshAlgorithm=1;

Mesh.RecombinationAlgorithm=1;//blossom
Mesh.RecombineAll=1; //all

Mesh.Algorithm=8;//delquad mesher

Merge "offset_mesh.stl";
CreateTopology;

Compound Surface(200)={1};

//Surface Loop(300)={200};
Volume(301)={300};

Physical Surface (501)={200};
Physical Volume(502)={301};
=====

but I get the error:

Error:  The point set is trivial.
Error   : Self intersecting surface mesh, computing intersections (this
could take a while)
Error:  The point set is trivial.
Error   : Surface mesh is wrong, cannot do the 3D mesh
===

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.

Many thanks,
