Urgent: ANSYS modeling – how to round the inner and outer walls at the junction of a cylinder and a nozzle?

This of yours should be solid modeling. The AFillT command can be used to select the two intersecting surfaces that need to be chamfered, and then a solid model can be created using those chamfered surfaces along with the cylinder’s mating surface; subsequent volume addition operations can be performed. Here’s a small example you can take a look at! ***************Environment Settings************************ finish /clear /filn, E42 /title, FEA of connecting zone of nozzle to cylinder /units,si ! Use international units! *********Parameter Settings********* Rci=1000 ! Inner radius of cylinder tc=30 ! Thickness of cylinder Rco=Rci+tc ! Outer radius of cylinder Lc=4000 ! Length of cylinder Rno=530 ! Outer radius of fitting tn=15 ! Thickness of fitting Rni=Rno-tn ! Inner radius of fitting Li=193 ! Inner extension length of fitting Ln=500 ! Outer extension length of fitting rr1=30 ! Radius of the fillet on the outside of the weld rr2=15 ! Radius of the fillet on the inside of the weld pi=1.2 ! Internal pressure pc=pi*Rci**2/(Rco**2-Rci**2) ! Axial equilibrium force at the cylinder ends! ****************Preprocessing*************************** /prep7 et,1,95 !

I can’t understand the command stream; it’s frustrating

Not bad, not bad. I am also learning *ANSYS; for now, I can only create models manually. Where can I find the command stream?
