Happy New Year to all. I am doing quite long simulations, and I would like to know if there is a way that saves all the calculated information to later load the saved information and continue calculating where the simulation has been. For example, I do a simulation of 10 seconds, I analyze it and now I want to simulate up to 20 seconds but starting from the 10 seconds already calculated Thanks a lot

Thanks for your reply, Marcel: How could I get information about Local Truncation Error when I used the solver Trap? Is there a specific command in NGSpice? R1 1 2 0.1 R2 2 0 1 R3 2 3 1 R4 3 0 1 R5 3 4 1 R6 4 0 1 V1 1 0 10 .op .end Joaquín

Thank you very much Marcel: I am testing a simple example and it seems that I already understand the information. With the Sparse package, can I get information about accuracy and LTE ?? How can the full Sparse package be used? Joaquín

Hi all: The matrix A, I understand that it is the one corresponding to the following relation Ax = b, in the mdump file, the following 3 lines appear: Warning : The following matrix is factored in to LU form. Circuit Matrix 3 real 3 1 1 1 1 5e-08 2 1 -5e-08 1 3 1 1 2 -5e-08 2 2 0.00124998020426496 0 0 0.0 Is it possible to have more information about the mdump matrix? How is it built? What does each line and column mean? Thanks

Hi Holger: I have tried to store the number of iterations but I can't. With rusage all> ru.txt I get information like the previous image, but how can I get a .txt where all the iterations come out? I would like to make an analysis of the error made but without this information I cannot estimate it

Good afternoon: I run my RC model and I have the information from the attached figure. It is possible to save the information from the figure? e.g. total iterations or matrix Thanks in advance

Thanks a lot. I will try what you have recommended to me

Good afternoon everyone: I am new to using NGSpice and I am starting with simple simulations and I have some doubts: 1-I have an RC circuit and I would like to know if I can obtain in a .txt document the iterations used for convergence 2-I have read in several messages that niiter.c can be used, but how can I implement this file? Exist any example? Thank you
