- Demonstration of FieldML 0.2 ? format by Richard Christie, Caton Little and Randall Britten.
Representation using FieldML 0.2 ? format of heart model's geometry, converted from of original heart.exnode/heart.exelem dog heart model using a custom conversion which sampled the original 60 element model geometric field. This model consists of 60 elements with RC coordinates interpolated using tri-quadratic Lagrange basis, original used prolate spheriodal coordinates, with 60 bi-cubic-hermite by linear elements. The fibre field has not been converted yet.
Files:
heart.xml = the fieldml model
heart_mesh.connectivity = bulk connectivity data (27 local to global node indexes for each element)
heart_mesh.node.coordinates = bulk coordinate parameters (3 RC coordinates per node)
fieldml_heart.cmgui = cmgui command file to show (Note: only runs in as yet unreleased development versions of cmgui.)
fieldml_heart.png = image of the triquadratic heart
