Why doesn't the grid on the plane connect to the already constructed grid on the neighboring plane?
I have a three-dimensional geometry ready. The common faces and edges of solid are executed correctly. I checked through the correctness of the geometry in various ways: Surfase Reapair use ctrl+J through the review context menu through the ID of the lines that make up these surfaces From all the checks, I conclude that…

Coax-Fed and Line-Fed Dipole Models in FEKO — Feed Simplification
Hello, I am working on modeling a simple planar dipole antenna in Altair FEKO using two different feeding approaches. My goal is to simplify the feed model for use in array simulations with an infinite ground plane, while ensuring that the results remain consistent with a more physically detailed coaxial feed model and…

Hypermesh CFD _ Rotational Periodic Boundaries
Hello, I am creating a sim using rotational periodic boundaries. Both surfaces are identical in shape and size and have identical meshes. The issue I am having is when the sim is run almost all the nodes on each face as part of the boundaries are shown as undefined which creates the following error repeatedly for all…

what are the difference between coupled solution and the structural solution with mapped temperature
I noticed that the results from the same models with coupled solution and the structural solution with mapped temperature and pressure are different(from pdf of heat transfer analysis training), is it because that within the coupled solution, the displacements of the model will be sent to flow solver to recalculate the…

Best workflow to simulate a free-free modal test with soft springs in HyperMesh
Description: I am moving from a free-free modal analysis to a configuration that should represent a free-free experimental modal test setup. I want to support a plate using very soft springs at its nodes, so the model is held in space but still behaves almost as free-free. My idea is: • the springs should act normal to the…
