Ansys Maxwell simulation problem

Click For Summary

Discussion Overview

The discussion revolves around issues encountered while using Ansys 18.2 Maxwell 2D for transformer analysis, specifically regarding unexpected simulation behavior where analyses complete too quickly without producing results. Participants explore potential causes and solutions related to simulation setup and installation errors.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant reports that simulations that typically take about half an hour are now completing in just a few seconds without errors or results, suggesting a potential issue with the solver.
  • Another participant questions how there can be no error, result, or solution, and suggests posting screenshots for comparison.
  • A participant mentions that the problem occurred immediately and notes an error at the end of the installation, indicating it may be specific to Maxwell as other simulations worked fine.
  • One participant proposes reverting to a previously functioning model to compare inputs and setups to identify discrepancies.
  • There are repeated requests for information from a user who may have encountered a similar installation issue, indicating a desire for shared solutions.

Areas of Agreement / Disagreement

Participants express varying experiences with the software, with some suggesting installation issues while others focus on simulation setup. No consensus is reached on the root cause or solution to the problem.

Contextual Notes

Limitations include potential missing assumptions regarding the simulation setup, the specific nature of installation errors, and the lack of detailed troubleshooting steps provided by participants.

I am using Ansys 18.2 Maxwell 2D to analyze a transformer by using transient and magnetostatic solvers. Normally the analyses were completed correctly and took time like a half an our . But right now the simulations are comleted suddenly(in few seccond) and there is no error no result and no solution. I mean, I guess the program not solve the simmulation but there is no error, Everything looks like correct. Is there anybody to help me to fix this situation.
Thank you...

Welcome to the PF.

Is it having trouble converging in the initial conditions? How can there be no error, no result and no solution? Can you post screenshots of what it used to look like and what is happening now?
 
These are from the latest analyze
There is no error or warning. The simmulation is completed in 3 or 4 second (Normally it takes about half an hour especially for transient solver

)
The following images from older simmulation (different simmulation). It was run correctly, I obtained all results correctly. Also this analyze is not working, Same situation is appeared when I reanalyzed

Did you find the solution for this problem ?
 
I assume you had it working and then it stopped working?

If that is the case then why not revert to a functioning model, and then compare all model inputs, excitation, analysis setup, mesh etc to see where the dif lies?
 
In my case, the problem has occurred straight away.
However, i found out that there were an error at the end of the installation (see picture below) :

The problem only occurs with Maxwell. I tried to solve a simple circuit with simplorer and it worked just fine.

@ ilCapitano can you tell me how did you solve the above problem at the end of installation?

Welcome to PhysicsForums. :smile:

It looks like @ilCapitano has not been back here for a couple of years, so you may want to start your own thread with your question.
 
This thread has become a necropost magnet, so I'll tie it off now.
