Thank you very much ! Please share within your group !

[@shubhamlakhpati6477]

Your videos are very helpful sir...In today's world no no one gives such a free and effective teaching..Thank you once again... Do you conduct any online training course..??If so then I am ready to pay for it..Please let me know..

[@graspengineering9249]

Thank you for appreciation ! We do online training but at present we are working on ANSYS Online Coarse which will be very useful in terms on learning, getting confidence in ANSYS & FEA.

what is the use of solid extension (beta) you have used in 8:00 min of the video

[@graspengineering9249]

Hello Naresh, It is for solid extension. If you are doing any solid extension then we need to use this function.

Sir when I extrude head to 10inch and click generate the result still shows 1 Part, 1 Body but in your video it becomes 2 Part, 2 Body. Is there any setting for this.

[@graspengineering9249]

While doing extrude use Add frozen option instead of Add material, Add frozen means it will not merge the bodies but will create separate bodies.

Can i swich my model Designmoduler to mechanical window and vice versa

[@graspengineering9249]

Yes, You can Do changes in design modeler and then update the mechanical window. But design changes are not done in mechanical, it will be done only in design modeler.

[@nisargchauhan6595]

@@graspengineering9249 ok,i wanna change system coordinate first in mechanical window Nd then i want to go with this same changes in design moduler .how can i do that?

[@graspengineering9249]

@@nisargchauhan6595 Hello Can you plz define your purpose of doing this ?

[@graspengineering9249]

Create plane in design modeler (using X & Y axis coordinates)and export that coordinate (having option below..keep yes), you will see same coordinate in mechanical window

Sir, please add meshing tutorial for this geometry.

[@graspengineering9249]

You can refer meshing videos on our channel page. We have nozzle shell junction, pressure vessels meshing videos.

@@graspengineering9249 Thank you very much for your reply, Sir. I have seen that video. I would like to know if any special mesh control we need to provide for offset nozzle to generate uniform meshing.

Offside nozzle layout

[@graspengineering9249]

what ?

[@davidbrowne89]

Hi there, apologies in advance but technically so performing any analysis to help reduce stress at the nozzle-to-shell connection is bad engineering practice. Furthermore, from a Code perspective, re-pads are implemented to compensate removing the metal representing the internal nozzle bore area (otherwise known as the "area replacement method"). The underside of a re-pad to ellipsoidal head surface is in fact frictional (0.2 typically for steel-to-steel). The weld elements are actually "joining" the ellipsoidal head to pad to nozzle components. In practice, any displacements incurred due to nozzles loads for example will cause the pad underside surface to "slip" against the ellipsoidal head surface while the welds essentially absorb that induced stress. Trying to claim any stress reduction from a solid pad and shell is strictly not accurate and cannot be used for Code purposes.

[@graspengineering9249]

Hello ! Adding re-pad means adding local stiffness which help to strengthen the local area resulting reduction in stresses and deformation. You can define friction between pad and shell (near nozzle area) but both will going to come in contact due to applied loads so better to consider glued connection. Which code says stress reduction is not accurate due to Re-pad ?
