Hello!<br><br>I am trying to add landmarks to a FEM registration for 3D volumes. When I try it with the existing example for 2D (DeformableRegistration1 with FiniteElementRegistrationParameters2.txt) everything goes fine, but when trying it in 3D it crashes. <br>
<br>For testing purposes I just use one landmark. Everything works (landmark file is read) until the program arrives to AssembleKandM() function of itkFEMSolverCrankNicolson. Inside this function there is a call to the function GetLandmarkContributionMatrix(). The program crashes at this point, it does not even enter the mentioned function.<br>
<br>I am confused about this since the 2D case works, and the only difference for the 3D case (using DeformableRegistration11) is that the element type is itk::fem::Element3DC0LinearHexahedronMembrane instead of Element2DC0LinearQuadrilateralMembrane.<br>
<br>Do you have any idea of what could be the problem?<br><br>Greetings,<br><br>Cristina<br>
