    Coaxial feed excitation using FEM modal port

    Hello, I have been trying to excite the coax feed using a FEM modal port, however, I am seeing an error, which says "Missing buffer zone for the FEM region when decoupling MoM and FEM". Can somebody please help me understand what this error means and solution to this error ? The outer cylinder of coax is copper and the inner cylinder is a pec. Also, is there anyway in FEKO to accelerate meshing for large structures? Attached is the design that I am working on. I really appreciate any suggestions or help. Thanks. DESIGN_MOM_updated.cfx
  2. Hey Guys! I have faced the next problem when I tried to Import CAD or Fine Element Model With Mass and Inertia in Motion View. The STEP file was imported and you can see on the attached image the „bodies” but the „graphics” aren’t visible. It is written at the Graphical source that "error evaluating". I tried to import in the 2017 version of HW, but it didn't work due to importing/conversion error. What did I do wrong? Could you please help me in this matter? Thank you for your help in advance! Best regards, Tüki

    How can we use FEM line port

    i have used FEM line port but i have gotten the following problem any suggestions, because my purpose is to eliminated the effect of loads (the loads do not be effected by the incident field) thank you
  4. Hi, I want to add temp point on my model and do analysis and then in Nastran output or fem output I can read the analysis (displacement or stress of that point), i mean in output the temp node be like a grid point or sth that analysis performed for that too. Best, Mohammad
  5. Hello all ! This is my first post here, I'm a student doing my master thesis in Mechanical engineering. Here is my issue, I successfully did the tutorial in order to realize dynamic explicit analysis with the "full car" model available in Hypermesh database and also the " Example 51 - Optimization in RADIOSS for B-Pillar (Thickness optimization) " in order to understand how the ESL method works. The next step is to optimize the car crash box using he ESL method, my aim is to optimize the component called " COMP-PSHELL_1 " by Thickness optimization. I wrote the .radopt file but I encountered an issue with the .fem file. See below the error, I was not able to solve the issue. *** See next message about line 14864 from file: fullcarv5.fem "CONTACT,3,3,0,3" *** ERROR # 1000 *** in the input data: Incorrect data in field # 4. See attached the .radopt, the engine/stater file and the .fem file Thanks for your help ! Aub N. fullcarv5.fem fullcarv5.radopt fullcarv5_0000.rad fullcarv5_0001.rad
  6. Hello everyone, The figures below compare the AFDEX predictions and experiments of a bevel gear manufacturing process composed of an enclosed die forging stage and a consecutive sizing stage. As this is a representative process in near-net shape manufacturing, a precision simulation is required. Figure 1: Process 1 - Enclosed Die Forging Figure 2: Process 2 - Sizing Figure 3: Enclosed Die Forging - Comparison Figure 4: Sizing - Comparison Cheers from AFDEX Support Team!

    1D BEAM ANALYSIS

    Hi, I am currently carrying out a 1D beam analysis. My results and the contour on my beam seems patchy and unclear. I have attached the file of the beam and results for you to understand. It is a distributed load of 150N between 32mm-109mm and 222mm-299mm. Could you please tell me how to make the contour line more visible. I have tried to change the range, but it did not make a difference. Thank you, Yousif 1D beam.mvw 1D beam.hm
