Hi, Mehdi. The time of the plot state in d3plot that you’re looking at precedes the time reported in the Warning message. I assume that’s the reason you don’t see evidence of all the deleted elements in the view of the geometry.

Make another run with the hourglass type set to 4 and the hourglass coefficient set to 0.03 (for the timber). If you still get rampant element deletion, it would then be prudent to scrutinize your input for the *MAT.
