Transport Delay in Realtime simulation

Hello,

I set the simulation time to "inf" in order to be able to change the parameters during real-time.

However it seems that Transport Delay block is not working in this mode. When I switch to finite time, it is working, but then I can not change the parameters real-time.

How to solve this?

Thanks

M.

Hi @Mirko Novakovic,

The Transport Delay block pre-allocates a buffer based on the simulation stop time. When the stop time is inf, it cannot allocate the buffer, so it fails to work correctly. Use the Variable Transport Delay or Variable Time Delay blocks, which do not rely on a pre-allocated buffer.

For more details you can go through the following documentation:
