Static Analysis Method
Select the static analysis method to be performed.
The selection of an appropriate analysis method for the size and scale
of the structure affects the efficiency of the analysis.
Skyline
This method is most widely adopted in structural analysis programs. The
method is applicable irrespective of the type of analysis, the scale of
the model and the system settings.
Band
This method is suitable for a small model and a model with an ABD(Almost
Block Diagonal) stiffness matrix. Similar to the Skyline Solver, the method
is applicable irrespective of the type of analysis, the scale of the model
and the system settings.
Multi-Frontal
Sparse Gaussian
The high performance Multi-Frontal Sparse Gaussian Solver(MFSGS) is a latest
addition to the group of MIDAS solvers. The MFSGS uses an optimum frontal
division algorithm to minimize the number of calculations for simultaneous
linear equations.
The MFSGS
is especially useful for those finite elements that contain a large number
of degrees of freedom.
Structures with many nodes can be solved
over 10 times faster depending on the cases. The MFSGS
is a particulary useful solver for the detail analysis of a structure
consisted of plate or solid elements.
Note
For linear buckling analysis, Multi Frontal Sparse Gaussian Solver significantly
reduces the analysis speed.
Multi Processor
Number
of Processors: Enter the number of CPUs.
Note
Multi-Frontal Sparse Gaussian Solver supports the multi-thread capability
in order to enhance the analysis speed. For a computer with 2 CPUs, the
solving time can be reduced between 30-40%.
Memory for Analysis
Enter when the analysis is to be performed
using only a part of the memory in the system.
If Auto is selected, the program uses appropriate
memory for the analysis after it determines the state of memory in the
computer.
