This came up the other day as well. A Node is a DofObject, so you can call node->n_comp(sys_num, var_num) to see how many components are associated with the node. So you just need to make sure that node->n_comp(sys_num, var_num) > 0 before you try to call node->dof_number. David On 02/18/201

[Libmesh-users] loop over nodes in mesh

2013-02-18 Thread Jens Lohne Eftang
I'm looping over nodes in a mesh. My mesh has HEX20 elements to accommodate 2nd-order approximation, but currently my approximation is 1st order. What's the proper way to loop over the nodes in the mesh (to get the dof indices) in this case? Currently I'm doing for( MeshBase::node_iterator nod
