tem_property_module Module

Module to describe additional elmental properties, like boundary conditions.

Every element in the octree structure can be assigned several properties. The description of the properties is kept abstract, such that very different properties can be assigned to elements in a similar manner. As 64 bits are available to describe additional properties, we could attach 64 different kinds of data to each element and each one combinable with all other properties. The most important data that has to be attached to elements in nearly every mesh are the boundary conditions in tem_bc_module, others are for example vertex displacements in tem_vrtx_module and regional influences. As the boundary conditions are such a basic part of the general mesh description, we present their property implementation exemplary in more detail. Each property is indicated by a bit in the property bit-mask. Which bit is attached to what kind of property is defined in the header file. The property might then be linked to further information stored in additional files. See tem_bc_module for details of the boundary implementation.

The amount and kind of additional data that might be attached to the elements by the properties is arbitrary and could involve several more indirections. For example an additional non-elemental file is typically required to describe vertex displacements of elements. Thus, for elements, where the vertices should be moved, there is an elemental list of integers indicating which vertices to use for the eight corners of the element. The actual coordinates are stored in a separate file with the coordinates for each vertex.

Element properties: each element might have up to 64 properties attached to it the bitpos indicates just the position of the bit in the field indicating, which should flag the corresponding property A 0 indicates the absence of the property and a 1 the presence Thus, an element with all bits set to 0 has no additional properties Must be smaller than 64, because the respective bits will be set in a 64-bit integer.

deallocate the property and header lists accordingly.
