3D Solid FEM

3D FEM analysis using linear tetrahedral elements. Also a modal analysis is shown.

Description

The precise method of setting prediscribed boundary conditions, point loads, line tractions, surface tractions, volume forces and the shown eigenmode, can be derived easily from taking a carefull look at the main program.

• Required Products: MATLAB
• MATLAB release: MATLAB 7.14 (R2012a)

I got the same error when using the Matlab 2008 version, but it worked fine with the R2011a version. In my case the error was circumvented anyway because I obtained the facevertex data of the tetrahedra (for my geometry) through other functions so did not have to use the Delaunay triangulation.

There some error. For ex:
??? Error using ==> cgprechecks at 14
OPTIONS should be a cell array of strings.

Error in ==> delaunayn at 48
cgprechecks(x, nargin, cg_opt);

Error in ==> delaunay at 48
tri = delaunayn([x(:) y(:)],options);

Error in ==> MainProgram at 17
CM=delaunay(X(:),Y(:),Z(:))';

Could you help me?
