Transient analysis in Multisim is a type of simulation that allows engineers and designers to analyze the behavior of an electronic circuit over a specific period of time. This analysis is useful for understanding how the circuit will respond to various stimuli, such as changes in input signals or changes in environmental conditions.
One of the main benefits of transient analysis in Multisim is that it can provide a more accurate representation of a circuit's behavior compared to other types of simulation, such as DC or AC analysis. This is because transient analysis takes into account the time-varying nature of signals and the inherent delays that occur within a circuit.
To perform a transient analysis in Multisim, the user must first set up the circuit to be simulated and define the time frame over which the analysis will be performed. This can be done by specifying the simulation time, the time step, and the type of analysis to be performed (such as DC or AC). The user can then apply various stimuli to the circuit, such as input signals or voltage sources, and analyze the response of the circuit over time.
One of the key features of transient analysis in Multisim is the ability to create and analyze different types of waveforms, such as sinusoidal or square waves. This allows the user to study the behavior of the circuit under different types of input signals and understand how the circuit will respond to different types of stimuli.
Overall, transient analysis in Multisim is a powerful tool that allows engineers and designers to accurately predict the behavior of electronic circuits over time. By taking into account the time-varying nature of signals and the inherent delays within a circuit, transient analysis provides a more accurate representation of a circuit's behavior compared to other types of simulation. This makes it an essential tool for understanding and optimizing the performance of electronic circuits.
Transient Analysis not happening in real time
The Transient Analysis window opens. The system keeps taking the data in incredible small steps, less than one micro second and approximately 1 mili second correspond to one actual second, so I am still puzzled. However changes to TMAX or TSTOP cause the high voltage results. Isn´t that too large? I'm a long time 20yr pspice user who is converting over to Multisim. In this example you executed the simulation three times in order to get the step responses of the RLC circuit, however, you can also use.
Run a Transient Analysis on the Multisim circuit in Fig. 7
Analysis parameters for the Transient Analysis. The SPICE model probably is going to behave differently, ignoring conditions that in real life will not work like having 1000 A running through a resistor I have exchanged the resistor on your circuit and the transient worked correctly. I do not think the issue is the model or the topology. For Initial time step: Time step must be greater than 1e-12 and less than or equal to the maximum time step. Diego H National Instruments Thanks very much Diego! In fact, in Multisim Live, this sentence "Simulation does not occur in real time.
Thanks for your time to help me out with this Diego. Finally, the results, voltage versus time, are presented in the Grapher View. I'll make sure to use the general Multisim resistors from now on. You will need 360,000,000 memory locations 1,440,000,000 bytes using single-precision floating-point data type per quantity probed. I found that my original NI Multisim 14 schematic bombed out at about 100 millisecond.

Each input cycle is divided into intervals. You can reset all the parameters to their default values by clicking the Reset to default button. Instead, the results just drop to zero unexpectedly , so it points towards a software glitch - maybe. The reactance of C2 at the resonant frequency is ~36 ohms. There may be other means to do this, but this is all I could find for now. This abstracts away the complexities associated with SPICE syntax and configuration of an analysis. This analysis divides the time into segments and calculates the voltage and current levels for each given interval.
It's likely that the default is microseconds. End time TSTOP End time of Transient Analysis. These analyses range from the basic to sophisticated. This would then present the output as current vs time on the grapher display. This analysis divides the time into segments and calculates the voltage and current levels for each given interval. As you can see, this is the typical underdamped response of a series RLC circuit. This is from the sample circuits inside Multisim.
Must be greater than start time. But in other circuits it worked for the time we wanted. I want to be able to run current vs time but the currents aren't part of the variables list. Since α depends on the value of the resistance, you will use three different values for R: 40 W, 200 W and 1 kW. However, in my simulation, there is no pop-up message that indicates a simulation error.
You are right about the timestep. The Transient window shows the units for TSTOP, TSTEP, etc are in seconds, your idea that maybe behind the scenes the time unit were micro seconds was clever but it seems that is not the case. Multisim performs Transient Analysis using the following process: 1. Each tutorial in this series provides you with stepbystep instructions on how to configure and run the different SPICE analyses available in Multisim. I just want one data point per second because the discharge is rather slow, however the simulation keeps occurring in micro seconds steps.
Thanks for trying to help me out here. The issue occurs when I the resistor is present - in series with the inductor. . These analyses range from the basic to sophisticated. Configuring a Transient Analysis in Multisim Publish Date: Mar 27, 2012 3 Ratings 5. To measure the phase shift between nodes V 2 and V 1 , two cursors are needed Step 1: Place cursor 1 slightly to the left of a maximum of the V 1 trace. The Grapher View window opens.
