How to check the E-field value for calculating power handling capability of my antenna?[V 2023.1]
Hello, I want to check the power handling capability of my conformal array antenna; for that, I created the near-field surface from the top of the patches to the cylindrical ground plane. I want to check the electric field value at the top of the patch surface, the dielectric layer, and the ground plane, because these…

Flux2D: Coupled Magnetic-Thermal Simulation with Moving Geometry
Hello. I’m working on a project in Flux2D 2023.1 which involves an induction heater that heats a moving laminated core as shon in the picture below. The application is Steady-State AC Magnetic field coupled with a Transient Thermal analysis with a 2D axisymmetric domain. I want the laminated core to move downward over time…

Mesh ratio size
hi everyone, case: 2D transient, flow over cylinder at Re = 20 000 - 100 000, SST Questions: What is the rule of thumb for mesh ratio size from edge to area of interest (nested mesh) to global mesh size? Should i use mesh ratio 1:2? For example, edge size = 1e-3 meter > nested mesh = 2e-3 meter > global = 4e-3 meter? is…

How can I reduce computation time and memory to run this array file ? [FEKO V. 2023.1]
Hi, Currently, I am running this Feko file using MOM with parallel solver, but it is taking more than 48 hours to complete with continuous frequency points and fine meshing. Is there any hybrid solver you can suggest to me in FEKO to run this file with less memory and less amount of time ? [I need fine meshing and a…

Modeling Hinge Joints in HyperMesh/OptiStruct for Linear Static Analysis
I am working on a linear static analysis involving hinge joints, as shown in the attached image. I have attempted multiple modeling approaches in HyperMesh and OptiStruct, but I am not getting realistic stress results. Approaches tried: RBE3 + CBEAM: I modeled the hinge joint using RBE3 elements for load transfer and CBEAM…

Is there a fast way to create lines in HM 2023.1
Hello Everyone, It may be a simple question: I'm looking for an efficient method to create a line in HyperWorks 2023.1. Specifically, I need to generate a line that originates from a designated starting node and extends for a specified length, with its direction defined by two other existing nodes. For example, consider a…

Unable to use tk_messageBox when executed in batch (noGUI) mode
When executing a script in batch (no GUI) mode in Altair HM/HV, using tk_messageBox does not do anything. The script executes the next step without any action. This issue seems to be observed first in v2023. I am using v 2023.1 and have not faced this issue in the previous versions. A solution to this would be much…

Does other loads step affect the result of normal mode analysis?
Description: [I am studying optistruct, and I am doing the analysis of a bracekt with center mass load. I add 2 loadsteps , one is normal mode, and the other is Gload. I found the mode analysis result would be changed per the Gload analysis type. If the Gload analysis type is non-linear static, the modes will be 145HZ…

How to create fastener vectors without geometry.
Hi everyone! This should be a simple question: how can I create fastener vectors without geometry? My component is a curved panel with holes for fasteners. I’ve already inserted RBE2 elements with a central node at each hole. Now I want to create a line/vector/coordinate system normal to the surface at each hole. I found…
