the NAFEMS paper looks like a vendor sponsored paper but is not. To ensure that you get the most efficient and productive CAD Software for your business, you should compare products available on the market. They said to me that SIMSOLID is not FEA but instead it is an FEM software which doesnt use meshing scheme. For these models the total solution time (including meshing time in SOLIDWORKS) is significantly less in SimSolid. Altair SimSolid utilizes the method of External Approximations. Simsolid’s technology is truly a revolutionary breakthrough which will have a profound impact on the future of product design. SIMSOLID is a fast application that is ideal for users that need to prepare models within minutes. With SimSolid, weld modeling is much easier, according to Welch. Fatigue can also play a significant part in a weld failure. Showing all 3 reviews. SimSolid provides a dialog interface to display reaction force and moment vectors for a combination of support, connection or parts. Overall: FEA analysis software at a great price. Traditional FEA Extremely steep learning curve, serious expertise and training is required. the latter is especially beneficial to individuals and groups who are watching their overhead costs. For example, here it is possible to match SimWise 4D’s overall score of 6.6 against SimSolid’s score of 6.5.

SimSolid is different. The objective of the training class is to provide knowledge of Altair® SimSolid for structural analysis. HyperMesh was used to transfer the CAD model into a FEA model, which was then used to run dedicated analysis and simulation tasks. ANSYS DesignModeler. Automotive chassis model with welds represented as cylindrical tubes. Get Results in Seconds to Minutes. Often, the weld is critical. However, the savings in model preparation were dramatic. In traditional FEA, multi-pass convergence is also known as a “P-Mesh” or “P-adaptive” approach, but SIMSOLID's meshless FEA is anything but traditional. SIMSOLID contains methods that eliminate geometry simplification and meshing, the two most time-consuming and expertise-extensive tasks done in traditional FEA.

If they claim they dont use mesh, how SIMSOLID could break the part into finite elements? Senior Vice President Business Development – SimSolid, Benchmark Establishes Significant Analysis Speedup in the Last Three Years. The last 3 models are relatively large and the timing for SOLIDWORKS vs. SimSolid is described below. The computational engine is based on breakthrough extensions to the theory of external approximations. In such a mesh, each point has a fixed number of predefined neighbors, and this connectivity between neighbors can be used to define mathematical operators like the derivative.These operators are then used to construct the equations … CAE Experts Needed to Make Engineering Apps, The Real-World Cost of a 3D-Printed Prototype, Engineering Design Platforms and Simulation in-CAD Benefit Product Development Teams, How to Design the Lightest Possible Bike – And Still Sleep at Night, Why Engineering Apps? The result is shown in Fig. Ken holds a B.S. For many engineers that use finite element analysis or FEA, it very important to know how to is properly model and obtain accurate solutions for complicated loading conditions such as shock loading. Remove All Products Add Product Share. These metrics are quite often a way to see how popular every service is and how extensive is its online presence. We are planning on adding 32GB RAM and an SSD. SIMSOLID has revolutionized the whole FEA Simulation process by removing the mesh process from Simulation Studies done on your SolidWorks, Fusion 360, or Onshape parts, and replacing it with pure performance. You have to spend hours eliminating details that, if left in, would choke the solver with a ridiculous number of tiny elements. About; Latest Posts; Ken Welch . Compare your results to your traditional or CAD embedded FEA and see for yourself what the thousands of satisfied SimSolid users across the globe have already learned. Detailed result settings were used – 6 adaptive solution passes for SimSolid and 1.93 million second order TETS for the reference FE analysis. All opinions are mine. Get Results in … SimSolid Both fast and accurate. Will I need to purchase a new CPU (like Xeon) if our FEA simulations will be pretty light, will just a RAM and SSD upgrade suffice? All told, the FEA solution took 27 times longer to model and analyze. “Since SimSolid only works on full 3D CAD geometry, fasteners are easier to apply, and this is extended further by several automation workflows. Altair has sponsored this post. SCORES FEATURES PRICING PRICING MODEL INTEGRATIONS. the NAFEMS paper looks like a vendor sponsored paper but is not. There is skepticism about SimSolid because it seems too good to be true, but it is for real. We currently have an i7-4790k and 8GB RAM. Hey! Altair has launched SimSolid 2019.0.1, is structural analysis software developed specifically for design engineers. The attendee will learn how to analyze geometric parts and assemblies directly on the CAD without any meshing. According to Greg: "Compared to FEA in SolidWorks, SIMSOLID by far gives us more data, reactions, things like that but we were using it within 30 minutes with no training. Components can be selected individually or in groups and forces/moments can be summed to understand load balance and free body forces. It inspects complex parts and large assemblies, using theoretical and traditional FEA. Both fast and accurate, SimSolid controls solution accuracy using a unique multi-pass adaptive analysis. Is SimSolid Accurate? 1 Results for FEA analysis using an extremely fine mesh. SIMSOLID is a new generation of structural analysis. Get Results in Seconds to Minutes SimSolid is fast, real fast.

SimSolid provides a simple one-dialog interface to display reaction force and moment vectors for any combination of supports, connections or parts. SourceForge ranks the best alternatives to Altair SimSolid in 2020. This is typical of joints commonly found in industry and from past experience I have found that conventional FEA codes have a difficult time achieving accurate results at stress concentration points, such as at the intersection of the two tube sections in this model. All default settings were used. In fact, studies have shown that this accounts for up to 70 percent of the time spent in FE modeling and analysis. All of this while performing a multi-pass convergence. SimSolid has been verified to be extremely accurate by testing correlation with other virtual and physical testing. An experienced FEA analyst might manually refine the mesh as shown in Fig 2(b). Is FEA linked to meshing? The original geometry representing the weld is suppressed. Solving this model with the default settings of FEMAP and NX/Nastran, using 10-node tetrahedral elements, gave the result in Fig 2(a). My initial experience with Altair SimSolid was positive. The Altair SimSolid result for the maximum stress was 10,477 psi, accurate to my reference result within 1.7%.

To fulfill the requirements for crash and modal analysis, the company used OptiStruct to optimize the component, RADIOSS and other external solver to run the calculations and HyperView for the post processing. Best of all, I found the adaptive analysis gave an accurate result in the high stress regions without all the hassle of meshing and remeshing that is typical with traditional FEA. Embrace the skepticism, download the free trial of SimSolid and do exactly what we did, test it out on your own models. Most FEA packages incorporate h-method, but only one historically, Pro/Mechanica, has relied on p-method. Result of meshless adaptive analysis in Altair SimSolid. What’s the Right Workstation for SOLIDWORKS. In recent years, these companies have been able to correlate the club head’s natural frequencies with the sound it makes when it strikes the ball and modal analysis has become an important part of the club head design process. Instead of using a mesh made of regular simple shaped elements it divides the model into arbitrarily shaped volumes. Permalink Submitted by ganesh.anandakumar on Mon, 2009-08-31 15:54. In addition, it doesn’t utilizes the point-wise DOF, popular with the traditional FEA.
