FILLPOOL,[Stiff],[Sensitivity],[EmptyLevels],[ShellArea],[offset],[stiff2]

This command fills a pool with solid water elements, a spring pool water/wall interface and the surface areas of the interface using shells. The pool is filled using an algorithm used in the EXCAV command where the floor of the pool and the wall Z-levels are used to create group solid elements to fill the volume. The interface of the pool wall/water are connected by a set of springs with the stiffness of these springs determined by user input. Finally a shell group is added that approximates the areas of the interface which may be useful in further processing of the pool in ANSYS®.

The user should create a sub-model of the pool to be filled before using this command. The pool model should only contain the walls and floor of a single pool to be filled. The walls and floor must be made of either shells or solids.

• Stiff - Stiffness of the Water wall spring interface parallel to the normal (Default 10⁶)
• Sensitivity - allowable variation in Z on the same Z-level (Default 0)
• EmptyLevels - Number of Z-levels, starting at the highest level, not to be filled by water (Default 0)
• ShellArea - Flag to produce shell areas. (Default -1)
  • ShellArea = 1 - Create the shell areas in the pool model
  • ShellArea ≠ 1 - Do not create the shell areas in the pool model
• offset – node number to start numbering of pool elements. This number should be greater than or equal to last node number from the original model if the user intends to import the water and spring group back into the original model. If the offset is less than or equal to 0 the pool wall node number maximum will be used (Default -1) An error will occur for any positive number that is less than the pool wall node number maximum.
• stiff2 - Stiffness of wall spring interface perpendicular to the normal. perpendicular stiffness used to model non fluid materials that may fill a pool (Default 0)
