I want to make a time average plot from 2D DEM data. In that case, I follow the following steps but when I applied these steps paraview window automatically closed. I don’t know why this is happening. please help me.
DES.FB1.RES in Mfix reader
DES.FB1.DES.VTK
Temporal statics
Extract region surface
plot over line.
