Simulation, or virtual prototyping, allows engineers to see the performance of their design in ways even lab testing cannot easily do. Even better, it’s often more cost-effective, more timely, and less laborious than everything you have to do to carry out a physical test. Something that valuable must be expensive and hard to implement, right? Not necessarily.GoEngineer has helped thousands of small to large businesses adopt and upgrade their use of analysis tools.

The material database, or material palette, is the repository for all solid and fluid materials typically associated with structural or fluid analyses. Out of the box, the material database of the 3DEXPERIENCE Platform is empty. To best represent your use case, we recommend creating custom materials based on your material data sheets or material test data. 

 

A beam analysis represents structural members as 1D line elements, with a set of section properties applied to represent the beam’s stiffness. Users benefit from this analysis in a massive reduction in computation time, but downsides are larger assumptions (and thus less detailed results) and more manual setup time. 

A partially filled tanker travels at speed, and then suddenly stops. The liquid inside its tank continues forward, slamming into the walls, then dissipating over time in waves. How much force does it apply on the tank? How long does it take to dissipate? Could a particular baffle design within the tank reduce the overall force, turbulence, and time to settle? We can find out more about tank sloshing using SOLIDWORKS Flow Simulation.

 

When a SOLIDWORKS part file, multibody part file, or assembly fails to mesh, there are a series of troubleshooting steps we can take. Failed mesh usually occurs due to one of three reasons. The mesh can fail for broken or interfering geometry. Use Tools > Evaluate > Check to test for sliver faces, or invalid faces or edges. 

A singularity is a function’s divergence into infinity. Simulation occasionally produces stress (or heat flux) singularities. In this article, we discuss avoiding singularities in SOLIDWORKS Simulation and how and why they occur. How do they singularities occur? Mathematically, the solver uses matrices to represent the elastic field (displacements of the elements).

The Remote Solver in SOLIDWORKS Flow Simulation is used to run flow analyses on a remote computer connected to the network. There are a few requirements including the remote machine must have the same edition and service pack of SOLIDWORKS Flow Simulation, SOLIDWORKS & Flow Simulation may use a network license or one standalone license, and the remote computer would ideally have a better processor and more RAM but does not need a good graphics card.

Complex features, like physically modeled threads, increase the rebuild times of SOLIDWORKS part files. Table 1 shows the rebuild times on a simple part with a thread created using multiple methods. This document will prove these rebuild times and explain the various methods used to create these threads.

 

 

 

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. The rest of this document will contain specifics on when the solvers will be less efficient and less accurate.
