Whats the problem in simulation in multisim

[samikhan0105]

I want to know that when i try to simulate it gives me error can anyone please tell me whats the problem is?

Hi Sami,

Are you running into a convergence error?

I was able to simulate your circuit by changing some of the simulation settings:

In Multisim 14.0, click the Simulate menu, and click Analyses and Simulation. 

Click Interactive simulation and click the Analysis options tab.

Click the Use custom settings radio button and click Customize...

Set the RELTOL value to 0.01. This should allow you to simulate without convergence errors. 

For more information about simulation errors, see How Do I Solve Simulation Errors in Multisim?

Cheers,

Jeff

Dear Sir,

I have applied the following settings which you told me in the link.. But I am still facing the same problem.

It gives me the error of Covorgence Assistant and when i run it , then it say

"Multisim Convergence Assistant Log

Step 1: Verifying Error Scenario
...could not reproduce the error
" and after words when i try to simulate it give me same problem.

I don't know whats the problem in it...

What version of Multisim are you using? 10.1?

Jcham I am using 14.0

Try setting your initial conditions to zero in addition to the above changes:

It seems this circuit is particularly sensitive to convergence issues. 

Also if you are using 14.0, the new measurement probes can be a very useful alternative to instruments and can help when running into convergence issues. 

Let me know if that helps,

Jeff

Thanks I find these above tool useful and the circuit is i dont know why is sensitive to convergence issue but above setting helped me out.

Thanks
