import forces hypermesh
I would like to read an external force into HyperMesh and apply it to my model. To do this, I use linear interpolation under Force. However, the problem is that the sum of all forces in HyperMesh is different than when I add up the values in the .csv. Where is the error here?

How can I output the total force acting on a single body in MotionSolve?
I would like to obtain the resultant force (total force vector) acting on a specific body in my MotionSolve simulation. I’m not interested in the contact forces individually, but rather the net force applied to the body from all interactions (contacts, joints, gravity, etc.). I created an output request of…

Hypergraph 2D Plots: Applying a custom function to multiple curves
I have a bunch of test data curves in acceleration (m/S^2) from a UNV file. I want to convert them to velocity in mm/s to compare with CAE pch file results. In this case, this is two operations (scale, then integrate). I general I want to be able to apply any user defined function to curves I have selected to either…

[Flightstream] 무차원화된 M2CN을 로터 디스크에 뽑는 방법
충남대학교 석사과정 박기정입니다. 이전 질문으로 non-dimensional normal force M2Cn을 프롭로터에 대해서 디스크에 contour를 그리는 것에 대한 답변을 받을 수 있어 감사했습니다. 이전에 공유해주신 파일을 이용하여 로터 블레이드가 한 바퀴 회전할 때의 전체 데이터가 blade section별로 나오는 과정은 확인 했으나 제가 원하는 데이터는 로터 블레이드가 한 바퀴 회전할 때 azimuth angle 별로 원하는 blade section의 데이터를 뽑을 수 있는 방법이 궁금합니다. 예를 아래의 사진 자료 통해 공유하겠습니다.

CFD-DEM-FEA three way coupling for water jet cutter
For water jet cutter, first stage is water pressing soil, second stage is cutter push soil, then cycle again.First stage requires EDEM-CFD coupling, while second step requires EDEM-FEA explicit dynamic coupling. as part of head, water jet spin with it. So CFD should change with FEA cutter head. Since there's no three way…

Sampling rate and stress plot
Hi everyone, I would like to ask two questions: I'm trying to increment the sampling rate for acquiring points of the curve by increasing NLOUT, NINT but I'm still getting the same amount of points. Do you know how to properly to this in order to have a smoother curve? In addition, I would like to obtain a plot like this…

Why is my model taking longer to converge even though convergence is good?
I have given DT=0.1, DTMIN=0.0001, I have not specified DTMAX. I don't why it's taking longer time to converge, Is it because of DTMIN? I have given only enforced displacement SPCD=30mm. It's converging but it is taking longer time to get solve. What is the preferred DT, DTMIN and DTMAX value. How the solver takes the time…

Delta Connected Open Windings PMSM
This article discusses how to simulate a delta-connected PMSM in PSIM, but first let me explain some differences of these two topologies. In a star (Y) connection, each phase winding is connected between a line terminal and a common neutral point. As a result, the phase voltage is lower than the line voltage by a factor of…
