Softening Butter with SOLIDWORKS Flow Simulation.

EmailFacebookLinkedInTwitterShare

When it comes to the Warren household, cookies are the dessert of choice (mine anyway), specifically Snickerdoodles. Nothing compares to the soft and buttery, cinnamon-sugar coated discs of deliciousness. I make these from scratch, and usually on a whim. This leaves me with one problem every time I make the cookies; the cold hard butter. I always forget to take the butter out of the fridge and give it time to soften. Then I must wait even longer to enjoy […]

SOLIDWORKS Flow Simulation Add-on Module Benefits – HVAC Part 2

EmailFacebookLinkedInTwitterShare

This is part 2 of a SOLIDWORKS Flow blog series. If you would like to read part 1 first, which I recommend, here is the link: SOLIDWORKS Flow Simulation Add-on Module Benefits – HVAC Part 1. The HVAC part 1 blog focused on solar absorption in transparent materials. Let’s focus on human comfort parameters for part 2. The Setup We use the same model from the part 1 blog with the addition of a simple desk and the figure of […]

SOLIDWORKS Flow Simulation Add-on Module Benefits – HVAC Part 1

EmailFacebookLinkedInTwitterShare

SOLIDWORKS Flow Simulation is a powerful computational fluid dynamics (CFD) tool. Two separately purchased add-on modules geared to the electronics and HVAC industries significantly enhance the program’s capabilities through functional and engineering database library additions. The focus of this blog is on one of the many tools added in the HVAC module – the effect of radiation absorption in transparent materials. To demonstrate, here is a room with 3 windows, an overhead HVAC vent and an open door. It is […]

SOLIDWORKS Simulation: Draft Quality and High Quality Elements – Part 1

EmailFacebookLinkedInTwitterShare

It’s all about the nodes and the equations!   At least that’s what my office mate, Chris, says. I’m not going to disagree with him, rather I am going to show that he is correct.  That statement arose while discussing meshing in SOLIDWORKS Simulation and getting reasonably accurate results with Finite Element Analysis.  That leads to the simple question “can I achieve accurate results using a draft quality mesh”? In SOLIDWORKS Simulation, the easiest method of differentiating between a draft quality […]

SOLIDWORKS Flow Simulation: Joule Heating

EmailFacebookLinkedInTwitterShare

SOLIDWORKS Flow simulation is a fantastic tool for simulating internal or external fluid flows. It also features very robust conjugate heat transfer capabilities; including conduction, convection, and radiation. The combination of these capabilities has made SOLIDWORKS Flow Simulation the go-to program to simulate cooling electronic components. It does this fantastically right out of the box, but with the addition of the Electronics Cooling Module, it gets even better! Today I’d like to cover one of the flagship capabilities of the […]

SOLIDWORKS Simulation: Reaction Moment Using Solid Element

EmailFacebookLinkedInTwitterShare

When running an FEA on an assembly or large part the first thing we normally do is reduce the complexity of the geometry so that the calculation times remain short. At times this would mean that we would get rid of the main structure and only calculate the reaction forces and moments on a subassembly or smaller region of a part. While doing this we may end up using tetrahedron elements, or solid elements, to mesh our geometry. Solid elements […]

SOLIDWORKS Plastics Venting Analysis

EmailFacebookLinkedInTwitterShare

Recently, I was helping one of our customers work through a large injection molding analysis using SOLIDWORKS Plastics. He wanted to verify weld lines and air traps as he was still planning gate and vent locations on the tooling. The part he was analyzing included many features, such as mounting bosses and stiffening ribs, on the inside. These features will all be on the core of the mold. The exterior of the part will have a near-smooth finish, an “appearance” […]

SOLIDWORKS Simulation Premium: An Overview of Dynamic Damping

EmailFacebookLinkedInTwitterShare

In this blog, I will provide an overview of dynamic damping, show examples of a system under various levels of damping, and give some insight on how to define damping in a SOLIDWORKS Dynamic simulation. For those seeking a deep dive into damping, this is not that blog article. What is Damping: According to Isaac Newton, “…an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.” This “unbalanced […]

SOLIDWORKS Simulation: Causes of Incremental Strain Error

EmailFacebookLinkedInTwitterShare

This problem comes in during the calculation of two consecutive time steps in a nonlinear analysis. If the material deforms drastically without some proportional stress increase, then the software will stop the calculation and throw up an error message. The message may read something along the lines of “Incremental plastic strain is too large”. The solution may not be straightforward as to turning on an option. When you’re working with metals or non-rubber like materials, you should dig into the model […]

SOLIDWORKS Plastics – Cooling Analysis Basics

EmailFacebookLinkedInTwitterShare

If you are in the business of designing plastic parts, you are probably well aware of the multistep injection molding process. SOLIDWORKS Plastics can simulate this process. Three different offerings (Standard – Professional – Premium) allow increasing levels of functionality. All of them can simulate the plastic injection flow stage; Plastics Professional adds the pack stage, and other capabilities and Plastics Premium includes the calculations related to the cool and warp stages. One thing you might not know about this simulation […]
