Abstract
EXTRACT is a computer program designed to extract a portion of a large finite element model to obtain more detailed displacements and stresses. In addition the program applies boundary conditions to the extracted region in the form of prescribed displacements obtained from a previous analysis of the large model. The extracted portion can be refined by the use of a special refining program or by hand modelling. Hydrostatic pressure on the portion, due to balance-on-a-wave loading, is applied by EXTRACT. The extracted model created, along with its associated boundary and load conditions, is in a form suitable for a finite element analysis to obtain displacements and stresses.
