Hello Dave,

thanks for the hint.

I used /config,noeldb,0 after the solve right before I leave /solu and enter /prep7, unfortunately I didn’t change anything.

 

…

D,bednodes,temp,Tbed

allsel,all
outres,all

Time,i*dt
solve

save


finish
/config,noeldb,0


/prep7
/GOPR  
/com,Start surf152 for radiation

esel,s,….
….
….
esurf
allsel,all

/com,End surf152 generation for radiation


! Restart of solution phase
/solu

…

 

If I plot the Temperature of the AM process I discovered something strange, the first three time steps are looking good. Material is extruded and then with the 4th time step the activation of the elements is no longer correct, suddenly elements are deleted again. I do not understand why 

Step 1

 

Step 2

 

Step 3
