Newton unit dimension - MotionView 2022.1
Hello, I have troubles with MV units. Curently, here are my solver units : In my MV model, I want to apply a torque, using a Spring Damper object. The units for the torque properties seems to be : N.mm.s/rad. Am I right for this ? Also, the dimension definition of the N in SI is : kg.m/s². But in MV, is N become kg.mm/s² ?…

How to plot matsum energy in hypergraph for a specific assembly of a full vehicle model(LS-DYNA)?
I have one full vehicle model(LS-DYNA). Which has around 2000 parts. in the vehicle there are various assemblies (e.g. door,tail gate, biw,….) now i want to plot matsum internal energy for these assemblies separately.(assembly contains many parts). FYI plotting matsum internal energy one by one for every part is not…

NOTE 32313: The *.str file is not valid for the current solution (checksum mismatch)
Hello, I am quite new to FEKO. I performed a simulation from start to end for a complex structure. Now I added an additional request on the results and it seems the calculation has to rerun the full solution as I get NOTE 32313: The *.str file is not valid for the current solution (checksum mismatch) Is it normal? Thanks…

PSIM initialization problem for generated code
Hi, I am using PSIM generated code with ADC and PWM initialization by PS_SysInit(2, 20). At same time, I needed to use I2C channel of f28377D. Thats why I used, Device_init() and Board_init() function generated C2000.syscfg. Is it possible to merge two separate initialization function together? The source code of Psbios.h…

/MONVOL/GAS: Monitor volume for tire, tank or air bag, Simple example model.
Overview: /MONVOL/GAS is a monitor volume which uses ideal gas EOS. This is easy to use. I will explain how /MONVOL/GAS works with a simple cube crash simulation. Exanple 01: No /MONVOL/GAS To understand diffarence caused by /MONVOL/GAS, I show a simulation without it. In the simulation, the cube is crashed by the heavy…

Regarding Hyperview Image capturing
Hi, while post processing results in hyperview, I need to capture the images by the default hyperview image capture, rather than capturing myself by using snip or Hyperview capturing options. the thing is like i need to capture multiple images in different hyperview windows, in a same image dimension and i don't want to…

PSD to Time Series OML Utility
Overview: This OML utility generates a time-domain realization of a signal from a PSD given as an input and writes it in a CSV file. It allows for visualization of both PSD and realization of the signal. The input PSD must be stored in a CSV file containing two columns, frequency [Hz] and magnitude. E.g.: 5,1.41E-02…
