which solver to use solidworks

Do i need to refer any output. If anyone could help me with this it would be.

Solving Flow Problems For Several Physics Such As Heat Transfer Species Transport Aerodynamic Combustion And Mult Engineering Problem Solving Cfd Simulation

SOLIDWORKS Simulation has four options for solvers.

. You can use other variable names when you enter them between double quotes. 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. The question may now arise why use the Direct Sparse Solver. Previously when you worked with large sketches the Automatic Solve Mode and Undo would repeatedly turn off in large sketches.

Utilizing the Remote Solver capability can be done with both network and stand-alone SOLIDWORKS Flow Simulation licenses and only a single license is required. If I force linear analysis to complete I get some unexpected large displacements. It doesnt seem to matter which solver my colleague selects. What is direct solver.

When comparing the speed of the solvers the FFEPlus solver was beyond doubt the faster of the two solvers when handling large Degrees of Freedom. Some time ago I had written a blog post comparing two solvers in SolidWorks Simulations FFEPlus and Direct Sparse. Use default setting Independent mesh to mesh bodies separately. Large displacement calculation - Solver failed.

There is a SOLIDWORKS Flow Simulation solver option which can be enabled called Flow Freezing. FFEPlus solver failed for constraint equations. In this case you dont need to do anything simply use independent mesh which is the default setting starting with SOLIDWORKS Simulation 2020. By using this setting the software will mesh each component independently.

The Automatic choice for a solver is the default option for Static Frequency Buckling and Thermal studies. Better to wait more but to have results to watch. While solving the static simulation i got error Solver failed and it show the large displacement. Because of the FFEPlus solver enhancements in SOLIDWORKS Simulation 2021 the overall solution time for this particular model that has 13 surface-to-surface contact elements of all total elements is decreased by more than 50.

JW By John Wayman 030920. This question has a validated answer. SimulationXpress uses FFEPlus solely. All of the solvers are based on LU decomposition.

These solvers will all arrive at the same answer for all well-conditioned finite element problems which is their biggest advantage and can even solve some quite ill-conditioned problems. Use always Direct Sparse or Intel Sparse make sure to have a lot of RAM FFE or other solvers should be used only if you are running out of core not enough RAM Set convergence tolerance to 1e-06. SOLIDWORKS uses the FFEPlus iterative solver by default unless certain conditions are present. The direct solvers used by COMSOL are the MUMPS PARDISO and SPOOLES solvers.

SOLIDWORKS will pick the most efficient and most accurate solver for the particular study automatically. SOLIDWORKS Simulation uses finite element analysis where every study is represented by a set of algebraic equations that must be solved simultaneously. Technology and advanced results visualization tools Dassault Systèmes SolidWorks Corp. Ive tried running linear analysis without large displacements but it suggests that large displacements is needed.

SOLIDWORKS Flow Simulation software provides the ability to share the calculations of a project over a network connection to a SOLIDWORKS Flow Simulation Remote Solver. The solver is literally from a time before GPUs existed and a recode of the solvers probably never floated to the top of the list in the software development team. This is just a guess though. How can i locate the part with large displacement.

This problem is too large for the solver try using a different one. Resources are then freed up on the local computer to continue other work without reduced performance as. Preview SOLIDWORKS USER FORUM Error. My intent with the simulation is to determine the stress generated in the angled bracket whilst restraining two perpendicular concrete lintels which themselves are supported on brickwork.

All you have to do is type in a name with or without double quotes SOLIDWORKS adds them when you dont and a value or equation. You can use the global variables. This option can be used to help speed up both steady-state and transient heat transfer calculations. It will slow down the run but its more probable to finish it.

SOLIDWORKS Simulation offers five possible solver options three direct and one iterative. When Automatic Solve is off a message in the status bar says Auto. Auto FFEPlus Direct Sparse and Large Problem Direct Sparse. Setting up a workstation to be used as a Remote Solver may seem like quite a daunting task however I will show you that this capability can be set up in well under thirty minutes provided you.

Height 12 is a working equation when you define the variable height as well. Under these certain conditions the Direct Sparse solver will be chosen automatically. Autodesk CFD uses a segregated solver. Now in SOLIDWORKS 2018 you can enable and disable SOLIDWORKS Automatic Solve Mode and Undo and modify the threshold limit for sketch entities.

By taking advantage of multi-core multi-processor computers SolidWorks Simulation can solve your engineering problems in an efficient and cost-effective manner. This video shows you how you can use the SolidWorks API and Excel Solver Add-in to work together to solve problems. The code behind the FEA solvers in SOLIDWORKS has its origins in a much older system called COSMOSM or Geostar from the 1990s. If you are new to Simulation always use Auto.

Solidworks Simulation is to switch the solver to Intel Direct Sparse. This example is of a plastic bottle. Has created an advanced simulation platform that can solve challenging analysis problems. The solver may also change during the solve.

There are two different methods to solve these equations direct and iterative. Use your SOLIDWORKS ID or 3DEXPERIENCE ID to log in. Regarding Solidworks and Ansys you need to ask their Technical Support Specialists They should be able to provide you with the right information. I hope this helps.

Im running a linear static analysis for a relatively simple contact problem.
