SOLIDWORKS Simulation: Linking Evaluator Results to Studies

EmailFacebookLinkedInTwitterShare

The 2020 release of SOLIDWORKS Simulation includes a new utility for study management. In a prior CATI blog, my colleague, Alon Finkelstein, introduced the Simulation Evaluator, which checks a study’s setup to determine if it will allow a successful simulation. He gave a great description of how the Evaluator verifies the results folder and material assignments and does a comparison of mesh/solid model volumes to ensure accuracy. I wondered about the usefulness of the “Results” section, and if I would […]

SOLIDWORKS Flow Simulation: Hydrology Applications

EmailFacebookLinkedInTwitterShare

With the addition of the free surface capability, SOLIDWORKS Flow Simulation can now perform simulations of more real-world applications. One commonly encountered Civil Engineering application in open-channel flow design is an energy-dissipation phenomenon called hydraulic jump, which occurs when a fast-moving, shallow flow encounters a relatively slow-moving, deep flow field. Fluid Mechanics texts classify open-channel flow using the dimensionless Froude number (Fr), which is a function of the fluid velocity (V) and depth (y) (ref. F. M White, Fluid Mechanics). […]

Everybody loves shortcuts, right? Who doesn’t like to save time and energy? Setup of SOLIDWORKS Simulation studies is no exception, so I’ll show some of my favorite time saving tips in the analysis of my small garden cart. You may notice that most of these tips are really just SOLIDWORKS CAD functions applied to Simulation, which shows just how well Simulation is integrated into the SOLIDWORKS interface! Hide Excluded Bodies: Simulation has its own set of options. Open the Options […]

SOLIDWORKS 2020 What’s New – Plastics Material Updates Summary and 3D Content Central

EmailFacebookLinkedInTwitterShare

There are several exciting changes to the SOLIDWORKS Plastics program for the 2020 release that will increase ease of use. A couple that I want to highlight are related to the database of polymer materials. First, a couple of vendors, specifically Chevron Phillips and RadiciGroup, have added 29 materials to the installed database. These are shown below. Also, 13 obsolete material grades from EMS-Grivory have been removed from the database. Second, 3D Content Central now has a library of polymer […]

SOLIDWORKS 2020 What’s New – Draft and High Quality Mesh Definition

EmailFacebookLinkedInTwitterShare

In the search for faster and more efficient simulations, SOLIDWORKS Simulation 2020 introduces new meshing functionality for linear static studies that is sure to help. We can now mix draft and high quality solid element meshes in the same study. Individual bodies can be meshed with either formulation to help reduce the total degree of freedom (DOF) count, resulting in quicker solutions. If you aren’t familiar with the concept, here’s a brief overview. Tetrahedral-shaped elements are formed when you mesh […]

SOLIDWORKS Flow Simulation: Calculation of Hydrostatic Pressure

EmailFacebookLinkedInTwitterShare

If you are an experienced SOLIDWORKS Flow Simulation user, chances are you’ve turned on the “Gravity” setting to account for buoyancy effects that exist when a fluid’s density changes with temperature. This is a very commonly used feature of the program. Buoyancy is an amazing physics principle that allowed the Montgolfier brothers to make the historic first “lighter than air” flight in Paris in 1783. One thing you may not be aware of is that when the gravity feature is […]

Bike Component Design with Remote Loads in SOLIDWORKS Simulation

EmailFacebookLinkedInTwitterShare

Do you perform analyses of assemblies in SOLIDWORKS Simulation that incorporate off-the-shelf components? We can usually exclude such items in the analysis, since they are typically rated for a certain load limit. I love cycling, so I’ll use the design of a bicycle drive system to demonstrate the use of Simulation’s remote load feature. The system consists of a pedal and crank arm on either side of the bike frame’s bottom bracket and one or more chain rings on the […]

Beam Diagrams in SOLIDWORKS Simulation

Are you aware that you can produce beam shear and bending moment diagrams in SOLIDWORKS Simulation? This useful plot type allows for quick visualization of these results along the entire length of a beam. I’ll show you the functionality using a classic example from any Civil Engineering text on strength of materials, the case of a simply supported beam of length “L” with a centered load “P” applied at the center of the span. In the analytical solution for shear […]

Flow Simulation: Computational Domain Editing Part 2 – Periodicity

EmailFacebookLinkedInTwitterShare

In Part 1 of this blog series, I covered the SOLIDWORKS Flow Simulation computational domain symmetry condition setting to reduce the size of the computational fluid dynamics (CFD) problem to be solved. The result is a decreased solution time and required computer memory. This blog will show how another computational domain condition, periodicity, can be used in those situations where you have a pattern of identical components in the flow field. I’ll continue to use the Lockheed F-117 Nighthawk stealth […]
