Dear Aniket,
When DREAM.3D creates a synthetic volume the volume is a voxelized structure in memory, meaning at the moment of creation there is not any kind of “Surface Mesh” created. After the synthetic volume is created, say near the end of your current pipeline insert the filter “Quick Surface Mesh” which will generate the surface mesh that you are looking for. Please note that while the generation of the mesh has gotten better in the latest release it is still possible to create a surface mesh that Abaqus may not be able to use properly. If you want to try our latest codes take a look at the nightly builds at http://dream3d.bluequartz.net/binaries/experimental/ then look for a directory with today’s date. Those binaries have some experimental new filters that do a better job of exporting DREAM.3D data structures for import into Simulation codes. The filter is called “Export 3d Solid Mesh”. The filter is still in development so if you have some feedback for the filter developer please let us know.

Dear Sir,
I am currently working with the DREAM 3D filter called "Export Triangle Geometry", but I do not have much idea how to work with it. In the Required Objects section it needs a Data Container which can either be the SyntheticVolumeDataContainer or the StatsGeneratorDataContainer. Selecting either one of the two makes me find either one out of the following two errors:
1) "Data Container Geometry is not Compatible", error code -384
2) "Data Container Geometry is missing", error code -385
I have also tried using the "Export ASCII Data" filter before the "Export Triangle Data" filter. In the "Required Objects" section at the "Attribute Arrays to Export" part , I have tried pointing towards StatsGeneratorDataContainer and the SyntheticVolumeDataContainer, but in neither case does the following filter (i.e., "Export Triangle Geometry" ) is turned on green or is activated.
Please help or suggest something to proceed with.

If you are wanting to export the actual surface mesh to files that you can read into MatLab I would suggest using the "Export Triangle Geometry" filter. It will write 2 files when used. The first is the Vertices and the second are the triangles. You can combine that with the "Export ASCII Data" filter to dump the associated arrays for those triangles and vertices. If you want to read directly from the .dream3d file I can help you locate the information you are looking for. A DREAM.3D file is just a HDF5 file and MATLAB can natively read those files.

Dream 3D,
I have created a mesh for a structure. I have some matlab code that I want to analyse the mesh. specifically I need to a matrix of the mesh nodes location, a matrix of the euler angles of each grain, a matrix of the which nodes are connected to each other and then a matrix that then has the face information (which three lines make a face).
I saw that I can export text files (ASCII) and that I can export the "FaceLables", and "NodeType" can I get all of the information I need from these two sources?
thanks
John
