miladramzy / Vibration-PINNs

This repository presents a series of analysis on the performance of Physics-Informed Neural Networks in vibrational systems. The limitation of PINNs in learning highly nonlinear systems with long temporal domains is discussed and the potential solutions are investigated.

What the function of "loss_velocity" is? #1

The loss_ics and loss_res is the restriction of data and residual. What is the function of "loss_velocity"?

miladramzy commented 6 months ago

Since there are two initial conditions to satisfy (initial displacement and initial velocity), two losses are defined (loss_ics and loss_velocity) to enforce such conditions.
