Hi,

(It appears I hit 'send' before I answered your second question.) If you want to write out a DenseMatrix, you can use the SCIRun::Math::CastMatrix module to cast it to a DenseMatrix before you send it to the MatrixWriter.

Cheers,
Dave

Hello

I am trying to extract the stiffness matrix from the low resolution mesh of the torso. I have the mesh.tvt.fld file being read in by the FieldReader. I have the FieldReader going to the SetupFEMatrix module and then both of these modules feeding into the BuildFEMatrixQuadratic module. I then have the BuildFEMatrixQuadratic feeding into the MatrixWriter module. I am getting an error that the field input to the BuildFEMatrixQuadratic has to be a TetVol type, not a TetVolField<int>. I have tried to convert the output from the FieldReader to a TetVol type, but with no luck.

Also, can I write the matrix to something other than a sparse matrix .mat file? How about a dense matrix .mat or something else?

Thank you very much.

Mark
