chrono::fea::ChNodeFEAfieldXYZ Class Reference
Description
Class for a node of a generic 3D finite element node with x,y,z position.
This is the typical node that can be used for tetrahedrons, etc. Note: this type of multiphysics node do not carry any ChVariable with it, because attaching ChVariables is up to some ChField. See also ChDomain.
