Making Simulation Time Fast

This depends mainly on your hardware (CPU; RAM etc)

hello aadil,
It has been already discussed. I believe simulation time , apart from power level used for transmission , is directly proportional to the number of sweeps we are using and the system complexity ( number of components and the type of components we are using in our system).
Please refer to the link below it may give you an idea about different factors.

SIMULATION TIME

Also as mentioned by Alistu in one of the comments that It really depends on how much the sequence length is reduced. An the bigger the network, the more time is saved when using a shorter sequence, since the signal is processed as a discrete vectors in any of these components and the shorter the signal, the more reduction in the time it is processed.

Hi aadilqau

As far as i have observed the simulation time mostly depends on the power level you are using in your system design.
Try simulating a system with 40 iterations at low power level and compare it with a system with less number of system sweeps but use a high value of power in this case.The simulation time of the first case will be small compared to the second one even when the first case is using large number of sweeps.
Reason being the fiber takes a very long time to allow a high power signal to transmit.

But ofcourse it is not always possible to work at very low power levels just to have a faster simulation.So even if sometimes a system takes long to simulate it is worth to wait to achieve a the required performance.

Thanks and regards

Hi Aadil..

That sure shall take quite a long time to get simulated. Well I’m sure you won’t be able to bring changes in the design to reduce the time. But I think you should divide the no. of sweeps, like you could have 10 iterations in one simulation and the rest of the 10 in another. This would at least help you in analyzing half of your results without having to wait for more than an hour.

In addition to this , you could refer to the link posted by Aabid in reply #32484.

Hi Aadil..

That’s not what I exactly meant. I meant that you could simulate for 10 iterations first. And then after that for another 10.
For parallel simulations, I am not aware if optisystem could have that inherent feature, but you could practically do that in case you can use two systems at the same time. You could use one system for 10 iterations, and another system for another 10 and simulate your projects in parallel.

Also, I believe if we have two operating systems in our PC, and Optisystem installed in both, we could divide our task on the two . I hope I have made myself clear.

HI AADILQUA….
As discussed already the simulation time depends on input power level.High power levels will indeed make the simulation time very long.
As already told by Damain in one of his comments that you can try modifying the Numerical parameters in the optical fiber parameters to tailor the engine. You can also try to enable CUDA simulation with your graphics card to speed up the simulation as it also depends on your hardware specifications.
with regards

Hi aadilqau,
The simulation time depends on system complexity and also on RAM of our Personal Computer. E.g if we use 3R regenerator in place of PBRS and NRZ/RZ , system will be less complex and hence takes less time, It also depends upon no. of sweep we are using.
