  1. When I tried to run one of the tutorials associated with the Modelica set that comes with Activate , I received an error message shown in the attached screenshot file. That message indicates "Modelica compiler requires Visual C++ compiler version >= 10". If I download and install the "Microsoft Visual C++ 2015 Redistributable Update 3 RC", do you expect that will resolve this error?
  2. Dear Experts, My Modelica sript contains the following equation: tan(gamma) = (y - y_b)/(x - x_b); where y, x, x_b, y_b are variables. Please let me have your advice how to avoid zero-division (to avoid to become x=x_b) in Modelica script. When I tried to insert the following statements in Modelica argorithm section: if abs(x-x_b) <= 0.01 then x := x_b + 0.01; end if; of cource, as you expected, Activate issued the error: system is overdetermined. Regards, Minoru Yubuchi
  3. Dear Experts, I would like to know how to switch two Modelica blocks based on a situation of the simulation. For example, please assume two SpringDamper blocks, A and B are contained in an Actibvate model which are applied at the same location. SpringDamper block (A or B)used in the simulation is decided based on situation of simulation and might be changed during the simulation. I created a model (attached) where MoCustomComponent based on Spring is used. In the model, spring constant of the Spring block can be switched during simulation but Spring block cannot be switched in this way? Are there any ways to switch Modelica blocks? Regards, Minoru Yubuchi Model5.scm
  4. Dear Experts, When I ran a Modelica script through MoCustomBlock in Activate, Activate issued the following error: [fmi2GetEventIndicators]: Error at t=7.5262725398123784e+000: index-1 and derivative evaluation failure Failed in updating zero-crossing surfaces. In what case, is this error issued and what should I fix generally? Regards, Minoru Yubuchi
  5. Dear Experts, I built a simple model that contains a MoCustomComponent block that represent a mass (see attached Activate model). The script in the block is just copied from Mass modelica block. The model issued the error (see the picture attched). What should I modify? Thanks, Minoru Yubuchi Samples_Modelica.scm
  6. 1Dモデリング & システムシミュレーション入門を開催します。 本シリーズでは、アーム機構の回転制御を例題として、Activateの基本操作および、Signalモデリング、Modelicaモデリング、連成シミュレーション、最適化方法を学びます。 対象のモデルはDCモータに接続されたアームを制御するものとし、シグナルブロックの制御モデル、Modelicaブロックの電気回路モデルおよびMotionSolveの機構解析を用いたアームもモデルが含まれますので、これらの接続方法を習得できます。また、Activateの最適化ブロックやHyperStudyとの連携による最適化手法も紹介します。小分けに解説動画およびモデルを配布していきますので、是非ご利用ください。 なお、本コースでは solidThinking Activate 2017.3 HyperWorks 2017.2 を使用しています。 1DシミュレーションツールAltair Activate : http://solidthinking.jp/product/activate/ マルチボディソルバAltair MotionSolve : https://www.altairhyperworks.jp/product/motionsolve activate_training_00_intro.mp4
