A modal analysis is first run to determine the natural frequencies and modes shape of a structure. They are intended to complement the SimSolid Fast Start Training Guide with additional instructions on several typical use cases. Simplification of the geometry is common to make meshing easier, but this can lead to errors if critical mass or stiffness features are left out. Q: When creating connections, I get the message, “Last task was completed with messages” and the message reads “Warning: Assembly has XX disconnected groups of parts”. This provides the ability to handle geometrical imperfections, as well as assembly contact imperfections like gaps, penetrations and ragged contact areas. Total time for Typical solution time on an 8-core Intel i7 was 4-minutes.. This will highlight where the missing connections are. SimSolid is really fast and is created … Altair SimSolid tutorial projects contain CAD models, SimSolid project files and complete workflow instructions. 4-step analysis –calculate first 3 flexible modes Import geometry, create connections Apply material property Create modal analysis & run Examine frequencies and mode shapes. The modal analysis calculated the first 10 flexible modes and took an additional 4 minutes. All runs are performed on a standard Intel I7 desktop computer with standard solution settings. A: Not all parts are connected. Complicating this further, many modal eigen-solvers are sensitive to the kind, size and shape of the elements used. SIMSOLID controls solution accuracy using multi-pass adaptive analysis. © 2020 Altair Engineering, Inc. All Rights Reserved. In traditional FEA, finding modes can be problematic. KW: Certainly. We are currently listed on Nasdaq as ALTR. Learn how to use modal participation factors in SIMSOLID. Additionally, the software utilizes distinctive multi-pass adaptive analysis to govern the accuracy of the solution. Modal – Modal analysis in structural mechanics is used to determine the natural mode shapes and frequencies of an object or structure during free or fixed vibration. You've come to the right place.

In SIMSOLID no meshing is required, so the entire process, from FUSION 360 to results, was done in under 10 minutes.SIMSOLID is next generation, high capacity, structural FEA. In SIMSOLID, thermal analysis assumes a … Learn how to perform a random response analysis in Altair SimSolid. Altair SimSolid makes the process of finding modes much easier. All runs are performed on a standard Intel I7 desktop computer with standard solution settings. Altair SimSolid calculates modal participation, effective mass and cumulative mass factors for each mode in a specified global or local coordinate reference frame. Results of a modal analysis on a 400 parts assembly in Altair Inspire, solved with the speed and accuracy of Altair SimSolid Complex solid parts can be analyzed in Altair Inspire without removing any of the geometrical features Thermal – Thermal predicts how thermal effects propagate through the model. Since it works with the full CAD geometry, the true mass and stiffness is better represented. The target with Altair SimSolid Professional edition is to extend our simulation capabilities to support both multi-step and chained analysis solutions. ONLINE SimSolid Introduction Altair SimSolid is a fully-featured structural analysis solution that can analyze complex parts and large assemblies efficiently on a desktop class computer. Improved CAD Integration for SIMSOLID Professional Every incarnation of SIMSOLID is able to integrate CAD. and M.S. Part of the Altair Hyperworks suite, SimSolid is the game-changing simulation technology for designers, engineers, and analysts that performs structural analyses … • First, make sure that the partition lines are visible by clicking on ‘Show part edges’ • Click on ‘Modal analysis’ icon in the horizontal toolbar at the top • Set the number of normal modes to 10 and click OK • Click on ‘Immovable support’ icon as shown below Here is an example of circular steel plate. Finally, here is a video of modes being calculated on a more realistic model. High frequency modes – modes 201 through 206. SimSolid FAST START TRAINING. SIMSOLID is a new generation of structural analysis. Structural analysis with SimSolid's speed and accuracy - as independently validated by NAFEMS - provides the ability to analyze large assemblies and complex parts. Adaptive solution refinement allows a single model to capture low to high frequency modes even for large assemblies. Take, for example, the analysis of a golf club driver. Autodesk Simulation Recommended for you. Sign up and start exploring the latest discoveries from Altair. The modal analysis used the same post constraints and calculated the fundamental frequencies and mode shapes. Integration, model and solve in SIMSOLID done in under 1 minute.SIMSOLID is next generation, high capacity, structural FEA. Demonstration #1: Modal Analysis. Altair will demonstrate additional powerful functionality of SimSolid, preview the upcoming SimSolid 2020 release, and introduce an exciting new integration with Altair Inspire. SIMSOLID modal analysis with modal participation factors of a large space truss — 549 part assembly. Stay Connected. Three modal analyses are performed on the unconstrained model that capture respectively the first 5, 50 and 200 flexible modes. This information is important for understanding the dynamic behavior of a structure. First, let us perform modal analysis on this model. It eliminates geometric simplification and meshing, the two most time-consuming tasks in other simulation software. We Dare You to Find Out! Inspire's award winning user experience for geometry creation and modification can be learned in just a few hours, and delivers dependable Altair solver power. This mode illustrates the ability of SIMSOLID to efficiently analysis a large assembly with parts of varying size scales (small to large) and varying geometric complexity. The crux of this analysis is the way SimSolid accomplishes it more efficiently on any desktop-class computer.
