A mesh chunk in DVS contains the underlying mesh coordinates and nodal variable information for a specific timestep/rank/chunk. It also is the parent object for [IElementBlock](class_d_v_s_1_1_i_element_block.xhtml "Element Block Interface for DVS Reader API.") objects which contain the element / connectivity information. Mesh chucks can be unstructured or structured (paralellepiped or curvilinear). See [DVS::IHash](class_d_v_s_1_1_i_hash.xhtml "Interface to get hash information from DVS objects.") and [DVS::IVarHash](class_d_v_s_1_1_i_var_hash.xhtml "Interface to get variable hash information from DVS objects.") for the hash object interface.
