Hello,

Seeking advice on how to modify Flow-3D to dynamically read in angular velocities and linear accelerations from an external table

I am trying to modify the QASDD.F90 Flow-3D file to output forces and torques at specified timesteps, use those forces and torques in a Simulink rigid body dynamics simulation, then the RBD simulation will output angular velocities and linear accelerations which would be read back into Flow-3D.

I have successfully modified the QASDD.F90 file to output the forces and torques and Simulink reads and process them successfully.

I am successfully adding a new line to the Flow-3D "move.inp" file at each timestep.

My struggle in getting Flow-3D to continue reading the move.inp file. It reads in the initial conditions at t=0, t=1, t=2. It will not read further lines past t=2.


Flow 3-D Detailed Log
------------------------
simulation time went past the motion table in movin file:
last data point will be used for the rest of the simulation
time = 2.00512E+00 last data point at 2.00000E+00
