I’m trying to simulate some faults using the BLDC Circuit in the PLECS Library. One of the faults is instantaneous power stop, which is pretty much a loss of power in the midst of the simulation. However, I am unable to … --- ## [Parameterize function-block via m-File](https://forum.plexim.com/t/parameterize-function-block-via-m-file/1196)

Hi, I use a m-File to write a function in the function-block in PLECS. The input variable of the function has to be a value that is recalculated in each simulation-step in PLECS. The problem is that I need to have this … --- ## [Change Sample Time during simulation in PLECS Blockset](https://forum.plexim.com/t/change-sample-time-during-simulation-in-plecs-blockset/732)
