How can I remove the hole in ground plane and add the wire probe in this step file ? [v 2023.1]
Here I am attaching the Step file of a probe fed microstrip patch. This step file already have a cylindrical probe attached with the patch. Also there is a hole in the ground plane of the antenna. How can I remove the cylindrical probe from this file and can add wire probe? How can I fill up this ground plane hole in this…

POWER CALCULATION FOR array antenna(V 2023.1)
Hello I am using an "active port" simulation for a 4x1 conformal probe-fed antenna array. My question is: when we select the voltage source for each port (see the screenshot), it is 1 V for each port in my array. Then what is actually the input power of my total array ? For doing the active port simulation, see my other…

EDEM CUDA API：How to specify particle names in an EDEM CUDA file
I have developed an EDEM body force API whose function is to apply force to particles named "FIX". My API code is correct, but I encountered an issue when writing the .cu file—the .cu file fails to recognize the particles named "FIX". I would like to ask how to implement this function in the .cu file? I have attached my…

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…

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…

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…
