Global User Window

With Radioss, it is possible to define a global user window. This is the most general interface between Radioss and external code.

To define a user’s window, two subroutines must be provided. One must be linked with Radioss Starter and the other with Radioss Engine.
  • The Starter subroutine is called USERWIS and is used to read the global data and to initialize global memory.
  • The Engine subroutine is called USERWI and is used to compute the forces and moments.
注: All communication between Radioss and the subroutines takes place within the argument list.
