Dear All, I'm conducting EDEM simulations with the various number of processors, for instance, 4, 8, 12, 16, 32 and 40 processors (CPU cores) in Unix computer of my university. In my simulation, there are 518 steel particles of 1 mm in diameter and they are getting attacked by sonotrode that vibrates with 20kHz. Even…
Hello, I'm working on a model with impactors in it. After defining the engine file(control Cards) and running the model, I can't find the strain and stress values in the .h3d. Can anyone help me figure out what to put in the engine file to have stress and strain?
i have downloaded thea for SketchUp however when i render it shows its watermarked and i haven't been able to access the licence agreement cant find it in my computer what should i do so that i can use thea without having its logo show up on my renders?
Subject: Unable to Load Component or File Error Description: Hello, I am encountering an issue while using hypermesh. When trying to load or run the program, an error message saying “No such file or directory” appears in the lower left corner of the interface, and I am unable to proceed with loading the model or component.…
Hi, I'm trying to do a time variant simulation in WinProp but I only found an example of moving the antenna through a trajactory. I think it's more practical that the antanna site is at a fixed position while the pattern is changing, or rotating. I wonder if there is a method to do so in Proman? Or actually Aman? I also…
Hello, I'm using EDEM and MotionView to simulate multibody link for shaking vessle. The motions are gived to joint like sin(Time). I want to use hyperstudy for change motions changing amplitude and frequency of motion like 2sin(time) or sin(time/2) How can I use two programs in hyperstudy?
Hi everyone! I'm trying to implement this transfer function in PSIM as shown below where K is the gain and t1, T1, and T2 are time constants that can be changed. This is based on the Generalized Droop Control for Inverters. - sample - I have tried simplifying the denominator into a second order equation and used a S-Domain…
I am running a multiple linear regression process on RapidMiner. It works. But now I want to calculate the Mean Absolute Error and I have to generate my own attribute to do this. So What I have done is I have connected Generate Attributes operator to the Apply Model Operator. The Generate Attributes operator has the column…
Hello, Where can I find/download the collection of indoor databases/files (Campus.idb, Small.idb, ...) that I can use while I try to learn WinProp and WallMan? These are referenced in the Altair WinProp 2023 Example Guide (08/18/2023) page 14. -Katherine
Dear all, I am extracting the mass matrix of a structure modeled with shell elements (CQUAD4) using OUTPUT,MATRIX,FULL,SPARSE. However, the rotational inertia corresponding to the nodes (with 6 DoF) is omitted in the .full.mat file. Below is an example of the results I am getting, for a lumped mass matrix, where the…
