Hello community, today i tried to follow some tutorials for SimLab with Flux for Magnetic AC Simulations. Therefore it is needed to use the Circuit Designer to setup the Current Source. Unfortunately it is not possible to move, edit by double click, delete or move the Circuit Components. I also tried SimLab v2024.1 - same…
Hello, I would like to restart my simulation from a previously run state and treat it as a new initial condition. Specifically, I run the simulation for 10 seconds, then I want to take that state and restart the simulation again from 0 seconds, applying different conditions or changes from that point onward. Could you…
I have a board now, and I need to move it up 50mm in the first working condition. In the second working condition, I need to move it up 20mm on the basis of working condition one. In the first load step, I used SPCD to move it up 50mm, and in the second load step, I used forced displacement to move 20mm and continuous load…

SLC Support REQUEST I’ve been trying to get ODS POWERPOINT to work, but I couldn’t get it running even in the simplest example. Below is the error message I encountered. Could you please take a look and advise? It might be related to the required Apache POI JAR files. Based on my understanding, installing the necessary…
Hello, I am trying to simulate a thin plate whose thickness has to go smaller and smaller. I have a problem because FEKO keeps meshing the edge of my structure with thin triangles : I understand that since there is a lateral face of small thickness, FEKO tries to keep the ratio of my triangles reasonable. However, I really…

Hi everyone, I am working on a motor and have completed the 2D electromagnetic design in SimLab. Now, I need to perform a thermal analysis to identify internal hotspots and verify the effectiveness of my water cooling. My strategy is to start with a 2D workflow for fast iterations before moving to a full 3D model. I have…
Dear support team' We are facing an installation issue while installing hyperworks version 2022.1 in our newly brought workstations. Please find the attached error images for your reference. We can have a webex meeting for solving this issue.

Dear , I am trying to model CGAP to model the clearance in bolted joints. This element is used to connect CQUAD4 with CBUSH on both extremities of the joints. I am checking this modeling techinique with a simple model before implementing it in a detailed model. In this model, the load is not transferred through the bolts…
Issue Description: > I am encountering a termination error in the RADIOSS Starter when attempting to use a custom material law (/MAT/USER01). Despite having the compiled DLL in the working directory and specifying it in the solver console, the solver fails to find the user interface routine. Error Log: > ** ERROR IN USER…
PSIM을 사용하던 중 라이센스 만료일이 다 되어 라이센스를 갱신하기 위해 기존 라이센스를 비활성화 하지 않고 새로 라이센스를 받아 PSIM에 입력하였습니다. 하지만 새로운 라이센스는 입력되지 않았고 기존라이센스가 계속 유효한 상황입니다. 그래서 비활성화를 위해 기존 라이센스 파일 및 코드를 확인해보려 하였으나 기존 라이센스 파일은 사라져있고 기존 라이센스 번호도 모르는 상황입니다. 이 경우 어떻게 조치해야하나요? 현재 확인되는 라이센스 파일은 새로 발급받은 라이센스 파일입니다.
Dear Team, In the e-drive motor control project (open-loop and closed-loop), we initially worked with Launchpad F280049C mcu using the GANINV board, and the system was working fine….In this setup, the *main motor control is executed on interrupt, configured with *ADCBINT1 and EOC2 mode. Later, we converted the same project…
Hello, I have been working through the EDEM API tutorial and successfully ran 3_Variable_Cohesion. I would like to apply this tutorial to a simulation with three different particle types. Could you please advise which files need to be modified and how they should be changed in order to support three particle types instead…
