• graph bot getting generated

  Dear Sir/Madam,I am not able to generate response for R-L circuit using electrical components-R,L, Ground, Power supply, cscope and clock.Basically, final integration time in set up is not getting set to 30 as per the cscope parameters.Though the circuit does not show any error but the graph is not generated as it should be.However, using transfer function and step input, I am able to generate but I want using R and L components.Pl help

• How to get an error message in XCOS?

  I have one simulation model and still did not figure it out what is the error as error message is not showing up. Thank youThe error is that my simulation work only for 0 second which is error but I dont how to overcome it. I will pay 400INR  for it if someone solve the error and explain me like tutions. Thank you  "[verboseMessage] time = 0] {} Kalman_Filter_SIM: Calling with flag Ending(5)"  "End of simulation for Kalman Filter block."  "[verboseMessage] time = 0] {} System_SIM: Calling with flag Ending(5)"</span>

• Require more spoken tutorial regarding Xcos

  As the descriptions are not available regarding the options available in palette, it is difficult to solve the assignment. And the physics of the question has to be understood before solving it.
