Re: How can I get my simulation results to match my experimental results?
Hello Yolanda,
Based on your simulation result (reflection coefficients are larger than 1), a PIFA antenna and its substrate were not tightly coupled due to not-enough meshes.
Since the number of the unknown of the (MoM) geometry becomes bigger (by finer meshing), I recommend you to change the substract part to the infinite multi-layer structure. (Then you don't have to worry about longer simulation time caused by the finer meshed .)
I ran the simulation with the attached file by using the multilayer as below.
Please check if there is any variation in antenna length or geometry or try more meshes with the attached model.

Re: Computer Performance
Hi Ibrahim
Are you using the system while the simulation is running? If so, the cores could be used by other processes of the machine, and EDEM waits to get the 32 cores (which is the max number). Although a little counterintuitive, you could try reducing the number of cores, and see if that makes any difference.
Also, how many spheres are there in each particle? Is that a big number? I ask this to decide if GPU would yield any better results for you.
Thanks,

Hi Sudip - would you be able to share your model ?

Re: Facing an error as Static Solver could not converge during quasi-static simulation
Hi Sudip,
Unfortunately from the image 'MBD Error.png' it is not really possible to find out what the direct cause is. Your model is not initializing, which means there is a major error which does not let the integrator proceed past time=0.
More information can be gathered by reviewing the messages panel at the bottom of the MotionView interface. This may show errors relating to missing entities or external files that can no longer be found.
As well, you can enable DEBUG mode for the LOG file, which will give more information about residual error in joints and bodies prior to lockup.
Hope this helps!

Re: Facing an error as Static Solver could not converge during quasi-static simulation
Hello Sudip -
Could you please check
- if there are any un-constrained bodies like dummy bodies ? A few ways to verify
-
- Turn on the Suspect data in the MotionView preferences. (If you are using the Classic interface, it will be under Tools > Options menu)
-
- Run a dummy transient run for a small time period. In HyperView, turn on all markers (Systems) and observe if one or more markers are falling off.
- There could be bodies that are not fully constrained, like a rotating body that might not be able to get static equilibrium or the equilibrium position may be too far away from the initial position.
A transient run can reveal these situations.
Hope this helps.

Re: INERTIA RELIEF ANALYSIS
are you running the model in a network? It might be related to slow response from the file transfer where you're running your model.
Avoid running the model into network/cloud drives.

Additionally, after creating a simple measure in HM, you just need to click the measure value again, and it will expand to show the X, Y and Z components.

Hi Zheng Guotao,
Please follow the instructions given in the image. Let me know if you have any difficulties.
FluxMotor HyperStudy connector for thermal behaviour in duty cycle
Hello,
I want to perform a DOE of a specific motor design inside HyperStudy. My goal is to get general information of the machine characteristics inside the base and maximum speed point and then perform a transient thermal study for every motor design (e.g. 120 seconds at a specific working point of each machine).
Inside FluxMotor, in the tab "Test --> Performance Mapping --> Since wave" I can define a duty cycle for the machine and see the transient thermal behaviour. My hope was to get the same functionality inside the HyperStudy connector.
My plan was to create a HyperStudy connector from the performance mapping--> sine wave. Unfortunately, the connector is able to extract general machine characteristics but not the thermal transient behaviour.
How can I implement this inside a HyperStudy project? It seems that FluxMotor is able to do so but once I create the HyperStudy connector, I am loosing this functionality.

Hi Zheng Guotao,
Yes, we have the same option which you can access as shown below. Please follow the instructions given in the image. Let me know if you have any difficulties.
