EDEM API Contact Model | Not working correctly: Bonded-Particle Contact Model V3.5.0
Hi Everyone, I have been trying to implement the Bonded-Particle contact model (v3.5.0) API provided by EDEM (from its previous EDEMSimulation forums), then it works fine. But when I tried to import the geometry model(.mesh file), the bead chain model created using the (v3.5.0)API broke into particles when it collided with…

How are the position at t=0 and gamma defined in Flux, and how is end winding impedance calculated?
Hi I am following the example "Flux - Twin Activate Coupling: IPM Motor Speed Control", focusing on Case 3, where the initial rotor position at t=0t = 0t=0 is set to 7.5°. I understand this is determined as the zero-crossing point of the phase-one voltage through back EMF analysis, as explained in the example "Brushless…

Altair SLC can read Excel spreadsheets, but can it read OpenDocument spreadsheets (*.ods)?
Altair SLC can read Excel spreadsheets, but can it read OpenDocument spreadsheets (*.ods)? Since installing OpenOffice.org/LibreOffice for office documents I have only had to use Excel files on client sites. OpenDocument spreadsheets (*.ods) are compressed XML file collections similar to *.xlsx files, so reading them…

Error activating license: License already exists in license store
Good day I tried to download and activate PSim on a new device on Monday (02/12/2024), I later realized that this is one of the limitations of the student license. I queried by emailing academicsupport@altair.com on Monday (02/12), however I needed to go on with work and I decided to use my old device until the license…

How to change the number of significant digits in the exported near fields file in Altair FEKO.
I've tried absolutely everything and can't find any information. When exporting near fields (*.efe and *.hfe) the number of digits after the decimal point is always 8, I need to increase it to 16. In the settings of the solver I specified to save data with double arithmetic precision.

NanoFluidX post-processing in Simlab
Is it possible to post-process NanoFluidX results within Simlab and not exporting them for a post-process in ParaView? It seems possible to me, since ParaView is considered an auxiliary tool and I have seen tutorial with post-processing operations in Simlab, but, can someone confirm it? Then another question would be: are…

PollexのPCB-level EMI DFEについて
こんにちは皆さん。 松川と申します。 題記の件2024/12/04にFekoに関するセミナーを受講しました。 その際資料のなかで以下が示されました。 使用によればGNDのスリットについてその際が示されています。 通常このようなスリットはアナログGNDとデジタルGNDを分割し その影響を受けないようにすることに用いられつと認識しています。 種々の情報からPollexではクロック信号のようなデジタル信号以外 電流分布は解析できず、Fekoへのデータエクスポートもできないと 理解しています。 上記の資料は正しいのでしょうか？認識が違えばご教授頂けますと 助かります。

PCB-level EMI checking with PollEx DFE
I was told by a Japanese distributor that Pollex cannot calculate the PCB current of analog signals. Looking at the top right of Page42, the difference in radiation noise due to the presence or absence of a GND slit is shown. In the PCB on the top left of Page42, it appears that the analog GND and digital GND are probably…

Is the Tab key no longer used?
I've recently upgraded to the 2024 version of HyperWorks from the 2022 edition. In previous versions of the "new" GUI, you could use the 'Tab' key to transfer from one selection field to the next. For example, in the split by surface tool you could select one surface and then click tab to move to the other surface…
