Hi Vikas,

I don’t know Meshlab that well, so I’m not sure of all the steps you are doing, nor is the included image very clear, but it seems that your mesh isn’t the right type.  You need to have a have a volume mesh (I think it needs to be tetvols).  If your field is a volume mesh, then there seems to be a lot empty space, which will not only make it difficult to place the dipole within the volume, but it will not allow any meaningful calculations.  If you send  the type of data that you start with in your obj file (tetvol mesh?  surface mesh?), I could probably give you some ideas to help you get what you want.  

cheers,
Jess

Respected sir,

I am trying to create mesh from CT images (.nrrd file or .fld file)..

Cleaver software is not working in my workstation. So I am trying the meshlab software.

1. I am writing the field output as .obj file.
2. Importing the .obj file in Meshlab.
3. From a simple tutorial, I did these steps to convert the field to mesh : Poisson disk sampling, compute normals, remeshing it with ball pivoting surface reconstruction.
4.I am exporting the mesh as .stl binary.
5. My question is, when I import in SCIRUN and applyFEMcurrentsource for a dipole inside the created mesh, the error is that dipole is not located within the mesh.


Please help me,  what mistake did I do in meshing   
I have attached the view scene of the torso mesh in SCIRUN created from meshlab

Waiting for your kind reply.
