Cyclic Symmetry Boundary Conditions Cyclic Symmetry Hypermesh Structure Cadfil Laminated Solid Model (_SOL) The Laminated solid/thick shell (_SOL) option is made of solid brick elements, this has one element through the thickness with the layer being a laminate stack of all the winding layers. ...
For analyzing the coupling relationship at the junction, coupling elements are introduced to build the coupling matrix. Based on a special procedure to deal with the global matrix assembly, the energy flow finite element analysis of the n-shaped plate is performed to solve the energy density. ...
Such an index makes nearest neighbour searches of nodes and elements much faster than sequential scans. An experimental evaluation of the mapping techniques using the index is conducted. The algorithms have been implemented in the open source finite element data exchange system FEDES. 展开 ...

In this chapter, we introduce the parameters needed to describe a node and an element. Next we emphasize the concept of using the simplest types of elements in developing a finite element mesh. We then derive, in detail, element shape functions [ N ] for some of the simplest 1D, 2D, ...
Data parallelism is achieved when each node runs one or many tasks on different pieces of distributed data. As a specific example, assume array A is shared among three machines in a distributed shared-memory system. Consider also a distributed program that simply adds all elements of array A....
Some of the first finite element problems solved were in the area of structural mechanics, and the early programs were written for computers with very little memory. Thus, first-order elements (often with special integration schemes) were used to save memory and clock cycles. However, first-orde...
Figure 7. Global aspect of the final mesh of the whole model with the empty cavities. When performing any analysis using a program based on finite elements, it is essential to select the most appropriate type of elements and attributes, which will depend on the specifications of the problem...
Likewise, each element of the double value set is necessarily also an element of the double-extended-exponent value set. Each extended-exponent value set has a larger range of exponent values than the corresponding standard value set, but does not have more precision. The elements of the ...
