ROMブロックの信号をベクトル化するスクリプト
Overview Altair ActivateのAPIを用いて、ROMブロックの信号をベクトル化するスクリプトを作成しました。 romAIやHyper StudyからのPyfitモデル、FMUのブロックは入出力ポートの数が多く、接続が大変な場合があります。 今回のスクリプトを使用すると、入出力ポートをmux, demuxブロックによりベクトル化しますので、接続が容易になります。 Pre-Requisite スクリプトとサンプルモデルはこちらです。 Usage/Installation Instructions Post-Requisite 使用製品：Altair Activate よくあるエンジニアからの質問はこちら

Script for Computing Shear Rates From a 3D Grid in EDEM
Overview This Python script computes shear rates for each point in a 3D grid in six tensor directions (zx,xz,zy,xy,yz,yx), as shown in Figure 1, using finite difference approximation. Shear rates for points at the boundaries of the grid are calculated by either forward or backward difference, and central difference is used…

Script for computing the temporal evolution of particle momentum along a vector in EDEM
Overview This python script computes the positive, negative, and total momentum of particles in a simulation, with reference to a specified vector. The script calculates the total, mean, standard deviation, minimum, and maximum magnitudes for each momentum type. The scripts calculates the momentum by multiplying the mass…
