Dear all, Sorry for the naive question. In short, I have a system with three variables (first order Lagrangian elements). I thought that for each of the node in the mesh, it would have a DOF attached to it with n_comp==1. However, when I used the following code snippet to check, the n_comp is actually 0 (not 1).
for (auto node : mesh.node_ptr_range()) std::cout << node->n_comp(0, 0) << std::endl; What I was trying to achieve is to iterate through all the nodes, and assign solution values to each variable DOF attached to the node from a Eigen::Vector3d. Then I got the error message about: Assertion `comp < this->n_comp(s,var)' failed. comp = 0 this->n_comp(s,var) = 0 Any help would be appreciated. Thank you!
