Product: ABAQUS/Standard
Relatively simple configurations were selected for these verification problems to ensure that analytical solutions or tabulated results could be found. In some cases certain parameters such as the distance between two surfaces or the number of elements on a surface were varied to illustrate the effects of these parameters on viewfactor calculations within ABAQUS. To duplicate the tabulated results for the cases where parameters were varied, the user can modify the input files provided with the ABAQUS release.
The number of elements along the bottom area can be varied to obtain the following results:
DCAX4 elements are used to discretize the surfaces of the cavity; one element for the top surface and two elements for the bottom surface.
The number of elements on each face can be increased to obtain the additional results:
Four DCAX4 elements are used to discretize each surface of the cavity. The infinite extent of the cavity is modeled by repeating the elements in the z-direction using periodic symmetry (NR = 10).
DCAX4 elements are used to discretize the surfaces of the cavity; one element for the top area, and two elements for the bottom area.
