Is it possible, if yes how, to simulate satellite in earth's orbit in MotionView/MotionSolve?
To introduce the problem I want to solve: I want to analyse the deployment of a satellite from a last stage of a rocket. Is it possible to use something like 'inertia relief' in motionview so I can have the satellite 'floating' in space? I want to avoid fixing the satellite to the ground so I can keep a high level of…

How to make multiple *DATABASE_TRACER requests while using LS-Dyna profile
I'm using the LS-Dyna solver interface in HM. I'm doing an ALE simulation and wish to measure pressure at certain points in air domain. In HM I can make a *DATABASE_TRACER keyword command and point it to a point in space ok. However within HM interface there does not seem to be a way i can make multiple entries of this…

How can I inject exported current from a older file to a new metallic rectangular surface?
Suppose I have some exported current values only from the metallic lines from any antenna model. I exported those current values in separate file. Next I created a completely new file in Feko which contains a metallic rectangular planar surface only. Now If I want to apply those exported currents to my new rectangular…

CPW waveport design in feko
Hi, I exported one patch antenna from cst to Feko. My antenna has no ground plane it has CPW feeding which I first modeled in CST. Now for the validation purpose I put it on Feko , I exported the model , define all substrate material then created the CPW feeding in Feko which is different method than CST. I created Edge…

Could you advice me how to determine optimal number of CPUs ?
Hello, My computer has 32 cores logically (16 cores) and 96 GB RAM memory. I am running my model by assigning 24 cores but it uses 30~50% of CPU when seeing the Task Manager. I think that MotionSolve should use 75%(24/32) of CPU or 100%(24/16). 1. Could you tell me the reason of low CPU usage (less than 50% of RAM is being…

Delete and Remesh Options
There was an option in the legacy preferences to delete and remesh modified surfaces. In the new interface, there's "remesh," "rebuild," "delete," and "dissociate." I'm trying to avoid creating an orphan mesh when geometry is modified post-meshing. Any tips for how to achieve this? Thanks, Mandy

Problem with: WARNING: inflow at outflow boundary
Good morning, As a new Altair user I am trying to run some first simulations in SimLab- focused on the flow and heat transfer topics. For the purpose of checking the potentials of the software I took some manifold CAD, we use. I managed to run some simple flow simulations, but while running the simulation with heat…

EDEM API: Custom particle factory
Hi, I am using EDEM 2020.3.1. Is there a way to plugin custom factory API when the model has cylindrical periodic boundary conditions? It is mentioned in the documentation of EDEM 2020.3 that this is not possible. But I also read that IPluginParticleFactoryV2_2_0.h can be used to plugin particle factories with cylindrical…

Estimation Saturation by plotting Torque versus Current
Hi everyone, i'm using Flux 2D to design a high torque motor. The current is high and somewhen there is a saturation (especially at overload). The torque and the current will not proportional to others. I want to draw this torque-current curve. But i dont know, if it's enough when i calculate it with magneto static (at one…

can ALTair products be used to predict heavy gas (Hydrogen Sulfide) concentrations distribution in outdoor environment?
Hydrogen Sulfide emits from tailrace, spillway, and reservoir of a hydroelectric power plant (HEP), disperses in ambient air, and tends to accumulate in low-lying areas. Its emission rate will be measured and its accumulative concentrations in surrounding area of HEP are to be estimated. The study area is a complex terrain…

I cannot open the Hyperworks bundle on my brand-new computer - the computer says it is unsafe. Has anyone else had this problem, and does anyone know a workaround?
I am on a student trial, though I have lost most of my trial days trying to access Hyperworks. The package won't open, as my computer says it is unsafe. It won't even give me the option to open it, which really means unsafe, because usually there's an option to 'open anyway.' I only have a few days left in my trial because…

Export particles' positions to a new EDEM project, to apply new material data
Hi Everyone, Is there any way to export particles (sizes and positions, once they have dropped and settled) to a new EDEM project, in order to study them with the different material properties? The idea is that I need exact same arrangment of particles (could be in large numbers), subject them to same conditions, but with…
