Winprop question，can Aman convert the phase of the antenna pattern?
I experimented with the converting 2*2D antenna pattern to 3D antenna pattern in Aman, however, I found that the 2D antenna pattern only contains angle and magnitude information, without phase. Does the result of 3D antenna pattern have phase? Can Aman convert the phase of the antenna pattern, or do all the antenna pattern…

How to select particular column while importing CSV file for field mapping in Hypermesh
Hi, I am having csv file with sl.no., X, Y, Z, Value data. Totally 5 columns in csv file. While doing pressure mapping by default HM will take only 4th column value as pressure data. but here the 4th column is Z coordinate values. I need to select 5th column instead of 4th column. Is there any provision available in…

Question about Acusolve-EDEM coupling
Dear experts, I would like to raise a question regarding Acusolve-EDEM coupling. As we know, the volume filtering method is employed to handle the fluid-particle interaction calculations during coupled simulations. However, if I want to simulate variable-density fluids (such as reactive flows, saline flows, etc.), has the…

Is there a way to deactivate my license without the original device?
My previous laptop, which I had been using, completely broke down. After purchasing a new one, I tried to deactivate the license via the tool in order to reissue it, but I got the following message "Error activating license: This license was already activated using different HostIDs." Since the old device is completely…

EDEM 2025: Spinning Friction Model
Description: While using EDEM 2025, I created spherocylinder particles. When adding physical models, according to the help documentation, the spinning friction model is not applicable in the friction model section. Therefore, I selected the standard rolling friction model. However, I noticed that within the standard…

Hypermesh Two different solids node connectivity issues
Hi I'm trying to model reinforced concrete. The pink area is going to concrete and the yellow part is for steel. I sketched a square and cut a hole, and then in a different component, I drew a circle. I extruded the whole 2D sketch and made it a solid. I meshed the yellow part in size 3.5 and the pink area average 8. I…

Is it possible to deactivate a license for renewal without access to the previous device?
I recently had my hard drive corrupt and when I went to open up Feko again to use my student license, it said "Error activating license: This license was already activated using different HostIDs." However, I don't have access to the other one so I can't deactivate it. Is there an easy way to get around that?

接触の微小な初期干渉を除去する ADJUST オプションの使用例
はじめに 理想を言えば、初期干渉のないモデルを作ることが理想ですが、どんなにキレイに CAD やメッシュを作成しても、それ等自身も、ある程度の交差を持って作成されたデータですし、実際に計算を実行する OptiStruct にしてもコンピュータ自身にしても、数値の丸め誤差があるので、初期干渉と、判定されてしまうことはあります。 目に見えて判断できるようなものは、メッシュで取り除いた方がよいとしても、あまり細かいところまで気にしていると、いつまでもモデルが完成しないので、ここは、OptiStruct 自身が持つ初期干渉調整機能を使うのがよいかと思います。 例題1、初期干渉をしてしまうモデル ダウンロード:…

EDEM visualizing cross section of a particle
Hi, When I make a slice plane of particles in EDEM, I want to visualize a cut-through of the particle if it lies between the clipping plane. It will be nice to color the outer shell of the particle and the core of the particle differently, so that viewers know what's happening at the particular cross section. ex) the outer…
