(It's definitely possible to use some better format here)<br /> 2) I use my own Python script which takes *.obj file and extracts mesh with specified material name from it. (effectively splitting the *.obj file into parts by material)<br /> 3) I use another Python script to take each part and "voxelize" it using VTK. Then I create 3D array and fill in material propreties corresponding to "voxelized" mesh into it (one by one).<br /> 4) Finally generated 3D array can be stored in HDF5 and loaded into MATLAB where it can be processed as usual.</p> <p>I should be able to provide example scripts for parsing *.obj files and "voxelization" using VTK, but it would still take some work to store voxelized results so they can be loaded in MATLAB.</p> <p>Filip Vaverka </p> http://www.k-wave.org/forum/topic/meshing-complicated-geometry#post-6918 Tue, 25 Jun 2019 09:02:58 +0000 Bradley Treeby 6918@http://www.k-wave.org/forum/ <p>Hi Firdaus,</p> <p>We don't have anything working out the box at this point.

What is the best way to prepare the CAD drawing and to do the meshing for k-wave simulation? Any step by step explanation?</p> <p>Thanks.</p> <p>Firdaus </p>
