The Direct Sparse solver requires about 10 times more RAM than the FFEPlus solver. It becomes faster with more memory available on your computer. The Large ...

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 multi-core processing capability, the Intel Direct Sparse solver improves solution speeds for simulation problems that are solved in-core.

If you set a higher value for the frequency shift, the Direct Sparse solver selectively calculates the requested number of frequencies, which are clustered around the shift value. Thus, you can avoid the computation of lower range frequencies (including the rigid body modes), which may be of no interest to your analysis, and save computational time.

Issues with FFEplus and Direct Sparse FEA solvers. I currently have a large FEA of a crane structure I'm doing ... Thanks Solidworks, I wouldn't have known.

27.02.2018 · SOLIDWORKS Simulation provides users with several options when selecting a solver, they include: Direct Sparse, Intel Direct Sparse, Large Problem Direct Sparse, Intel Network Sparse, and FFEPlus. With all these options how does a user know which one is correct for their simulation study? Fortunately, SOLIDWORKS has a procedure to automatically select solvers.

Large Problem Direct Sparse. A direct solver is available that leverages multicore processing capability and improves solution speed for static and nonlinear studies. In the Static or Nonlinear dialog box, under Solver, select Large Problem Direct Sparse. By leveraging enhanced memory-allocation algorithms, the solver can handle simulation ...

Direct Sparse solvers are recommended for Topology studies in particular. As for the Large Problem Direct Sparse, the user does not need to ...

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.

Direct Sparse solver; Large Problem Direct Sparse; Intel Direct Sparse; FFEPlus (iterative). In general, all solvers give comparable results if the required ...

With SOLIDWORKS Simulation 2021, the Intel Direct Sparse solver can now make use of all available memory. If it exceeds the amount of memory ...

Produces a direct solution using exact numerical techniques. “Sparse” refers to the sparsity (zeroes) in the matrices that it uses to find a ...

SOLIDWORKS Simulation offers five possible solver options, three direct and one iterative. To change the solver selection for a particular ...

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. The Direct Sparse and Intel Direct Sparse solvers are more efficient than the FFEPlus and Direct Sparse solvers at taking advantage of multiple cores.

Feb 27, 2018 · SOLIDWORKS will switch from Large Problem Direct Sparse to Direct Sparse if the study contains a moderate amount of no penetration contacts. Let’s look at the different solvers! Direct Sparse Solver. The Direct Sparse solver comes in a few different varieties, so I will explain each type separately.

15.01.2013 · SolidWorks simulation provides two options to solve the set of FEA algebraic equations; iterative or direct solution methods. The iterative solver, FFEPlus, uses approximate techniques to solve the problem. It assumes a solution and then calculates the associated errors. The iterations continue until the errors become acceptable. The direct solver, Direct Sparse, …

The Intel Direct Sparse solver can handle linear static and nonlinear studies with more than 4 million equations. The image shows the total solution time in minutes for a linear static analysis of a large model solved with the FFEPlus Iterative solver. The model has 1.0 million tetrahedron elements and 0.5 million contact elements with friction.

Choosing a Solver The Automatic choice for a solver is the default option for Static, Frequency, Buckling, and Thermal studies. In the case of multi-area contact problems, where the area of contact is found through several contact iterations, the Direct Sparse solver is preferred.

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 multi-core processing capability, the Intel Direct Sparse solver improves solution speeds for simulation problems that are solved in-core.
