huge temporary files
Hello Altair Communuity, I built a large finite element (FE) model and want to evaluate the stresses in the components. The problem is that HyperWorks creates a large number of temporary files during the calculation, which causes the calculation to break down when only a few elements are output (less than 100,000). If the…

Meta Particle Rotation
Good day, Please, I am a little confused about the rotation of a glued particle or similar shape when building a meta particle. When I try to rotate (30, 60, 90) the meta-particles around the X-axis, there seems to be no obvious change in the orientation because it remains in the same horizontal position as shown in the…

/INTER/TYPE{7,11,19,25} で、エッジでの接触の挙動の違いを理解する例題
始めに 本記事では、節点対エッジ(要素辺)、エッジ対エッジ接触が、/INTER/TYPE{7,11,19,25} でそれぞれどのような挙動になるのか、例題を通じて理解していきます。 なお、長くなるので、本記事では、/INTER カードについての細かい説明はしません。 例題の説明 ダウンロード: このように、3個のパターンで、青のシェル要素に緑のシェル要素をぶつけてみます。 節点対要素面接触 /INTER/TYPE7 節点体要素面接触の /INTER/TYPE7 です。 こちらの記事で、やはり節点体要素面接触である /INTER/TYPE25 との比較を行っています。 メッシュは 1mm 離して作っています。Igap=0 と…

Using the Flow Simulator Variable Editor
The variable editor in Flow Simulator (FS) is an easy yet powerful way to change many inputs quickly. If many model inputs use the same number (a hole diameter for example), consider using a variable to parameterize the input. Variables can be simple numeric input or an equation that can calculate an input based on other…

Linear Cohesion V2 Model Scientific Literature Reference
Hi all, I'm using the Linear Cohesion V2 model in Altair EDEM and trying to identify a scientific source to cite. The model adds a cohesive force of the form: F = k * A where A = π * R * δ, with R the reduced radius and δ the normal overlap. The cohesion parameter k is defined in J/m³ (cohesion energy density), similar to…
