SimSolidでECADを読み込んで熱応力解析
SimSolidは以下のようにECADを読み込むことができます。メッシュ作成をすることなく、少ない手間で熱応力解析を実施し、基板のたわみや応力を求めることができます。 Fig1. 対応CAD PCBのECADを読み込み、素子を熱源として温度境界や体積熱を与え、全体に対流境界を与えて熱伝導解析を実施します。 Fig2. 熱伝導解析の結果 (温度分布) 熱伝導解析で得られた温度分布を温度境界とし、線形静解析により、基板のたわみや応力を計算できます。 Fig3. 熱応力解析(静解析)の結果 (変位)

Simsolid: How to add weldment in a group of parts to have increased adaptive solution on weld
hello, I just started with simsolid. I did a study and it shows the max von mises stress on a seam weld location. Can I increase the solver adaptability on the weldment? I was able to create a group for the part on which the weld sits on for increased solver adaptation; but was not able to select the weld itself. What can…

Real versus actual measurments?
I am new to SimSolid. It seems very capable and has a lot of features I have not explored. But I have one area of concern, how does it relate to real world experience. Below is simple pipe: * 47” long * wall thickness of .065” * Material is as below, Chromoly steel. Note that I get very similar results with AISI 4140 steel…

Bolts resultant force
Hi I have a question. I am making a linear structural analysis for some parts and the results of forces on bolts are strange. Only 1 bolt out of 16, has significantly bigger force. It's weir, cause all bolts are same size, material nad theoretically they should have the same load as they are at same height of a cylindrical…

SimSolidで落下解析にトライ
はじめに SimSolidはCADデータを読み込めばメッシュ作成することなく迅速に解析できます。 しばしば、SimSolidで落下解析はできないか、という問い合わせをいただくことがあります。 そこで、Radiossで落下解析を実施し、剛体壁の反力を荷重として、SimSolidで過渡応答解析を実施し、応力分布を確認します。 ※前に剛体壁反力の1/2を適用としていましたが、誤りのため、訂正させていただきます。 本格的な落下解析をする前のあたりづけとして使うことを目的とします。 右側の添付ファイルに使ったファイルがあります。 解析モデル 以下のようにスマートフォンのカバー2部品を固着接触したものを対象としています。…

Parts that cross others in a separating contact
Hi all, I have a simulation assembly, where I have several parts pushing a tubes (with an separating contact, with a 0,15 of friction coeficient). The tubes are fixed, and the other moves sliding throw 2 guides and for some reason, this part cross the fixed part. In this assembly, I have 12 equal parts doing the same, but…

-How to impose a stiffness and block the degrees of freedom? What is the default stiffness? And what happens if we set the displacement to 0?
Hello, I want to impose a stiffness and block some DOF as a boundry condition but there is only grounded bushing which permit to do it, even i set up grounded bushing the simulation won't turn due to low constraints. I want to impose those boundry conditions.

Importing Revit Geometry in Altair Inspire, SimSolid and HyperMesh
In this video we will examine how we can export 3D Geometry created in Autodesk® Revit® to a STEP file. By exporting to STEP we can then import that fully featured geometry into Altair's Inspire, SimSolid, Hypermesh and more, for a traditional FEA, or mesh-free simulation without the need for any geometry simplification.
