im writing a program for an optimisation, which uses lsdyna for the calculation. Im using the Nodout option to get the coordinates and displacement of the nodes and use them further. But in the ascii file are only 6 significant digits written. Is there a way to increase the amound of significant digits, to get a higher precision in my follow up calculation?
I do not have a ready answer. However, I have a comment that might be food for thought: How many inputs do you have going into the model? What is the uncertainty in your inputs? As you know full well, the model itself is a highly idealized representation of the reality. Once you consider these aspects, 6 significant digits might be more than adequate.
In my experience, there are more significant digits when the data is exported/saved (to a .csv, for example) than what is shown in the ASCII plots. It seems like LSPP may round the data to declutter the plots.
My elout data in my most recent simulations reads ' 5.1223385526e-05', while the ASCII data in LS-PrePost shows only 6 digits, like you indicated. I hope this helps!
