custom STL, rename

[iJokerify]

Dear all!

I have created geometry in Blender and exported with STL.
Next, i’ve start to rewrite aorta3D code for my STL.
But the material numbers do not assigning.
The brief verison of code:

T len = 0.0362;
T r0= 0.01815;
T r1 = 0.01805;
...
superGeometry.rename( 0,2,indicator );
superGeometry.rename( 2,1,stlReader );
superGeometry.clean();

Vector<T,3> extend1( 2.*converter.getConversionFactorLength(), len, len );
Vector<T,3> origin1( -r0, -r0, -r0 );
IndicatorCuboid3D<T> cuboidInflow( extend1, origin1 );

//here i had tried 2 for the first parameter, result was not changed
superGeometry.rename( 1,3,cuboidInflow );

Vector<T,3> extend2( 2.*converter.getConversionFactorLength(), len, len );
Vector<T,3> origin2( r1-2.*converter.getConversionFactorLength(), -r0, -r0 );
IndicatorCuboid3D<T> cuboidOutflow( extend2, origin2 );
superGeometry.rename( 1,4,cuboidOutflow );

Geometry is the custom porous media.
Console out show this:

...
conversionFactorLength = 2e-05
[STLmesh] nTriangles=9030; maxDist2=2.592e-05
[STLmesh] minPhysR(StlMesh)=(-0.0018,-0.0018,-0.0018); maxPhysR(StlMesh)-(0.0018,0.0018,0.0018)
[Octree] radios=0.00256; center=(-5e-06,-5e-06,-5e-06)
[STLreader] voxelSize=2e-05; stlSize=0.001
[STLreader] minPhysR(VoxelMesh)=(-0.001795,-0.001795,-0.001795); maxPhysR(VoxelMesh)=(0.001785,0.001785,0.001785)
...
[SuperGeometryStatistics3D] materialNumber=0; count=1; minPhysR=(0.000825,-0.000455,0.001165); maxPhysR=(0.000825,-0.000455,0.001165)
[SuperGeometryStatistics3D] materialNumber=1; count=5812040; minPhysR=(-0.001795,-0.001795,-0.001795); maxPhysR=(0.001785,0.001785,0.001785)
[SuperGeometryStatistics3D] materialNumber=2; count=216527; minPhysR=(-0.001815,-0.001815,-0.001815); maxPhysR=(0.001805,0.001805,0.001805)
[prepareGeometry] Prepare Geometry ... OK
...

The STL mesh is cube with outside-directional normals with 13 porous cells inside with inside-directional normals. It’s like cube with empty cell’s edges.
I have add the cube there because i do not understand how else i can to do this model.
If it’s necessary, i am able to send the .cpp and .stl files from this project.
Help, please!

For me the output looks ok. You sould make sure that the stl is watertight and that the resolution requested really resolves the porous media. Best Mathias

Dear mathias,

what means the watertight? The stl haven’t holes on bounds of material ? Or exists some parameter of stl model which applying the watertight property to stl?

Grateful

when i increasing resolution, the progress is aborting “Killed” when Voxelizing. It means, there are some limit for resolution ?

Dear mathias.

I still cant to solve my problem. Can i send you photo of stl model and several questions about resolution via mail? I’ll be very grateful!

Redgards,

Hi iJoker,

I just send you an email.

Best,
