Automatic |
The software selects the solver
based on the study type, analysis options, contact conditions, etc.
Some options and conditions apply only to either the Intel Direct
Sparse or FFEPlus solver. |
Manual |
Select the solver to use for the
simulation. |
Direct sparse solver |
Selects the Direct Sparse solver.
Activate the Direct Sparse when you have enough RAM and multiple
CPUs. For every 200,000 dof, you need 1GB of
RAM for linear static analysis. The Direct sparse solver
requires 10 times more RAM than the FFEPlus solver.
|
FFEPlus |
Selects the FFEPlus solver to run
the study. This solver uses advanced matrix reordering techniques
that make it more efficient for large problems. For every 2, 000,000 dof, you need 1GB of
RAM.
|
Large
Problem Direct Sparse |
By leveraging enhanced memory-allocation
algorithms, the Large Problem Direct
Sparse solver can handle simulation problems
that exceed the physical memory of your computer.
If you initially select the Direct Sparse solver and due to
limited memory resources it has reached an out-of-core solution,
a warning message alerts you to switch to the Large Problem Direct
Sparse.
|
Intel
Direct Sparse |
The Intel Direct Sparse solver is available for static,
thermal, frequency, linear dynamic, and nonlinear studies. By
leveraging enhanced memory-allocation algorithms and multicore
processing capability, the Intel Direct
Sparse solver improves solution speeds for
simulation problems that are solved in-core. The Direct Sparse and Intel Direct Sparse solvers are more
efficient at taking advantage of multiple cores.

Intel
Network Sparse |
Use the Intel Network Sparse
solver to offload running a simulation to another computer connected
to a local network domain. See topic Simulation Help:Offloaded Simulation for more
information. |
