Plastics Tech Tip: Is the Plastics Solver Able to Use Multiple Cores?

EmailFacebookLinkedInTwitterShare

I often get asked for hardware recommendations for our simulation products and if  the solvers are able to utilize multiple cores.  One great value with our solvers like Plastics and Flow is that you do not get charged for using multiple cores and both solvers show great scalability when adding cores.  I wanted to quantify that scalability with a quick test today.My general recommendation and rule of thumb is that clock speed/number of cores affect solve times and memory affects […]

SOLIDWORKS Flow Simulation: Lift Up Your Design If you have ever done any aerodynamic testing, you know that wind tunnels (or time in one) are expensive and requires a lot of pre-testing setup and a lot of data gathering. After running the tests all day, next comes the arduous task of data analysis from the limited data you have collected. SOLIDWORKS Flow Simulation can help reduce the time and effort required to gather data about a potential aerodynamics problem. To […]

SOLIDWORKS SIMULATION TECH TIP: Transferring Flow Loads to Shell Elements

EmailFacebookLinkedInTwitterShare

In SOLIDWORKS, we have the ability to take advantage of an integrated interface where we can use multiple simulation tools. If you are using Flow Simulation and Simulation (FEA), you can export Flow Simulation loads to FEA studies. In the following example, I ran flow over a truck body and exported the pressure loads to SOLIDWORKS Simulation. The goal of this particular problem is to identify the displacement of a truck cap as a function of the aerodynamic pressures. In […]

OxyArm: Engineering a Medical First with Simulation How many problems do you need to solve while bringing a new product to market? Probably more than you want to think about right now. However, despite setbacks, looming deadlines and unforeseen circumstances, you manage to get the job done. When it’s over, you feel great. Well, I want to make it possible for you to feel better earlier in the design process with help from virtual testing. In this multi-part blog series, […]

SOLIDWORKS Flow Simulation: Coffee Cup Mixing and Cooling

EmailFacebookLinkedInTwitterShare

SOLIDWORKS Flow Simulation SolidWorks Flow Simulation is a very powerful tool.  Sometimes it can be fun to use a very powerful tool to simulate an everyday occurrence, just to see the results and to sharpen one’s simulation skills.  In this case, I have added an untold amount of milk and cream to coffee over the years and watched the beautiful swirls it makes as it mixes.  This article shows such a simulation using an assembly containing a cup on a table […]

SOLIDWORKS TECH TIP: Meshing Tips and Tools for Better Results (Part 1)

EmailFacebookLinkedInTwitterShare

Part 2 – Part 2 – Part 3 Since I am always being asked “what makes a good mesh?” I decided once again to blog about a list I put together a while ago. This was a general list, in no particular order, of things you can do, things you can use, and things you can look for, in creating a mesh.  And knowing you have a good mesh, you can feel better about the results you are getting. This […]

SOLIDWORKS PLASTICS TECH TIP: Counter Deformed Geometry Export to Counteract Warpage

EmailFacebookLinkedInTwitterShare

The primary goals of any plastics part designer and molder are to manage costs and hit critical tolerances. SolidWorks Plastics can help us predict part warpage and therefore optimize our design and process to minimize its occurrence. There are many factors that affect part warpage. Here are just a handful: – Part Geometry – Material – Fill time – Cool Time – Pack Time – Ambient Temperature – Gate Locations When we have done everything in our control to minimize […]

SOLIDWORKS Simulation 2014: New Features

EmailFacebookLinkedInTwitterShare

It’s time to start taking advantage of the new features in the 2014 release of SolidWorks Simulation that will make our lives easier. For 2014, I’ve compiled a quick video highlighting the what’s new features that simulation users will find exciting. I’ve grouped them into three main categories. Performance, Post Processing and Efficiency enhancements. Performance: Loading of Simulation Studies Solver Enhancements (non linear, iterative solver speed, new large problem direct sparse solver) Post Processing Results: Contact Pressure Plots in 2D […]

SIMULATION TECH TIP: Visualizing Results on Full Model of Analysis Using Symmetry (Sim 2014)

EmailFacebookLinkedInTwitterShare

SolidWorks Simulation 2014 will let you visualize results on the full model of an analysis using symmetry. In an analysis, you can use symmetry to create a portion of the model instead of using the full model. You just need to cut the model in half and apply Symmetry restraints on all the cut faces. Also, when appropriate, taking advantage of symmetry can help you reduce the size of the problem and obtain more accurate results. Up until now, results […]

SIMULATION TECH TIP: Contact Visualization Plot (Sim 2014)

EmailFacebookLinkedInTwitterShare

If you haven’t already heard, SolidWorks Simulation 2014 helps you visualize the applied contacts within your assembly analysis. With the new contact visualization plot, you can view how bodies are connected in multibody parts and assemblies. Before you run the analysis, you can detect the areas of contact applied by the global contact settings and any local contact sets. Not only does this ensure that you have created all the contacts that you need, but also confirms that you have […]
