Hi all, I'm currently working on a contact formulation for solid mechanics, and it requires that I'm able to get information at an arbitrary point on a boundary face on a cell. In particular, I need to get the convected bases at this point (one of them will be the outward normal to the face at the point, while the others, when mapped back to the reference cell, will give the other two isoparametric basis vectors). I see that there is a tool in the mapping class, namely Mapping::transform, that potentially caters for this but requires input information ( const InternalDataBase &internal) that I don't think one has access to through a public interface in either the mapping or fe_values classes.
Is there any function that I can use to get what I need or am I missing something obvious regarding the function I've described above? Thanks in advance for the help. Best regards, Jean-Paul _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
