15.09.2014 · SOLIDWORKS Simulation has four options for solvers: Auto, FFEPlus, Direct Sparse, and Large Problem Direct Sparse. SimulationXpress uses FFEPlus solely. If you are new to Simulation, always use Auto. SOLIDWORKS will pick the most efficient and most accurate solver for the particular study automatically.
SOLIDWORKS Simulation offers four solvers: Direct Sparse solver Large Problem Direct Sparse Intel Direct Sparse FFEPlus (iterative) In general, all solvers give comparable results if the required solver options are supported. While all solvers are efficient for small problems (25,000 degrees of freedom or less), big differences in performance (speed and memory usage) occur in […]
Feb 27, 2018 · To use the Intel Direct Sparse solver, the user must manually select the solver in the study properties. Direct Sparse solvers are recommended for Topology studies in particular. As for the Large Problem Direct Sparse, the user does not need to select this solver as SOLIDWORKS will automatically switch to it if the selected Direct Sparse solver ...
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. While all solvers are efficient for small problems (25,000 DOFs or less), there can be big differences in performance (speed and memory usage) in solving large problems.
By leveraging enhanced memory-allocation algorithms and multi-core processing capability, the Intel Direct Sparse solver improves solution speeds for simulation ...

2018 SOLIDWORKS Help - Analysis Solvers ... The Direct Sparse solver requires about 10 times more RAM than the FFEPlus solver. It becomes faster with more memory ...
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. While all solvers are efficient for small problems (25,000 DOFs or less), there can be big differences in performance (speed and memory usage) in solving large problems.
27.02.2018 · SOLIDWORKS uses the FFEPlus iterative solver by default unless certain conditions are present. Under these “ certain conditions ” the Direct Sparse solver will be chosen automatically. The solver may also change during the solve …
Direct Sparse solver; Large Problem Direct Sparse; Intel Direct Sparse; FFEPlus (iterative). In general, all solvers give comparable results if the required ...
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.
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.
15.01.2013 · The direct solver, Direct Sparse, solves the set of equations directly without any approximations and hence there are no errors associated with the solution process. There will still be discretization errors which are present both in iterative or direct solvers. A solver may be selected changing the study properties from the study feature tree.
