gaza Senior Member Przemek Join Date: Jun 2011 Posts: 249 Rep Power: 15	Hi all, I have a question if it is possible to make own monitor-expression which calculates in each iteration the difference of velocities from the current iteration and previous iteration in a whole mesh? If so, is UDF necessary? Can anybody provide sample UDF for that purpose? Any help will be appreciated. __________________ best regards pblasiak
