It is specifically designed for rapid events of this type, and introduces a more robust, and less time-consuming approach to drop and shock actions. SIMULIA Abaqus also features an implicit solver routine, but for these types of problems weвЂ™ll typically look to the Explicit solver. SOLIDWORKS Simulation generally uses an implicit solver approach, where each step in an analysis is fully converged and resolved вЂ“ great for static events, and gradually applied loads, but the timescales in something like a drop action are much smaller, making them harder to resolve.

Very rapid events вЂ“ shock, drop, impact, especially if they include nonlinear material behaviorДЇor todayвЂ™s handheld devices, drop testing is a critical part of the qualification process, and there are many other applications where a rapidly occurring event is an important action to test against.

The contact capability of SIMULIA Abaqus was a huge asset in resolving a very accurate solution to the problem, but additionally identifying contact features for each of those faces would not have been logistically feasible in SOLIDWORKS вЂ“ just like it would be challenging in the Jenga example pictured below. We recently completed an analysis project that featured contact interaction between a scanned model of a portion of the human body and a therapeutic device вЂ“ in all there were 50,000 unique faces interacting with each other. SIMULIA Abaqus offers a function called General Contact that will scan the model at each step, and automatically determine which faces may come into contact with each other as the analysis progresses. ThereвЂ™s also a usability difference in these situations вЂ“ SOLIDWORKS Simulation requires explicit definition of contact pairs between faces that might come into contact, which means each potential interaction between two surfaces has to be defined as a feature. SIMULIA Abaqus has a more robust contact solver, which allows us to resolve these contact interactions more effectively, and has richer control over some of the contact interaction options.

Seasoned Simulation Premium users will be familiar with occasional warning messages that indicate that the software is struggling with convergence at each step. Nonlinear problems with several contact interactions:Д®very nonlinear analysis tool has its limit over the amount of complexity it can successfully resolve, and SOLIDWORKS Simulation Premium starts to reach its limit as you include several вЂњNo PenetrationвЂќ contact interactions in a nonlinear analysis.However, there are a few classes of problem where weвЂ™ll typically prefer to start the problem with SIMULIA Abaqus, and here IвЂ™ve listed our top three. From there, weвЂ™ll spend additional time verifying the accuracy of our assumptions, confirming we have a suitable mesh, and exploring design alternatives (and all the other due-diligence that is an important part of making sure youвЂ™ve got a realistic and accurate solution). With direct integration with SOLIDWORKS CAD, and an analysis system that makes smart decisions for you, we can often have an initial analysis case, and first-pass results done within minutes of starting.

Hawk Ridge Systems has recently launched special SIMULIA Abaqus pricing for existing SOLIDWORKS Simulation customers, and the most common question we hear is how to decide which tool is best for a given situation вЂ“ so I thought IвЂ™d share the process we go through to select the appropriate tool to get an accurate result in the least amount of time when weвЂ™re working on applications for our analysis consulting customers.ДЇor analysis situations that involve linear stress analysis, estimations of natural frequency, or linear dynamic responses to shock or vibration, weвЂ™ll normally solve the problem using one of the SOLIDWORKS Simulation packages. These options offer solutions to problems that are outside the capability of SOLIDWORKS Simulation, or that would be significantly more time consuming to solve using that tool. You may or may not be aware that Hawk Ridge Systems provides two types of stress analysis tool and technical service to companies we work with вЂ“ the SOLIDWORKS Simulation range of stress analysis packages, which provide comprehensive stress analysis capabilities within the SOLIDWORKS CAD interface, and SIMULIA Abaqus, an incredibly powerful standalone analysis environment with a dizzying array of mesh, material, and analysis type options.
