Hi @lkirit2000
"It takes a long time to meshing."
- What is a long time? 10 seconds? 10 minutes? 10 hours?
- What mesh size are you using? Does changing the mesh size help?
- I suggest that you use the YZ Plane to split all of the surfaces of the model. When you do that, the mesh is fast. (I think the meshing has issues when the surface area is very large. By splitting all of the faces, the meshing has smaller regions to work with.)
"Load is applied vertical axial direction ?
Is this approach is correct or any other approach is available?"
- What are you trying to simulate? No one can say that it is correct or not when we do not know what the real situation is that you are trying duplicate.
- Your load does not makes sense to me. The force is applied to the top of the tube and to one edge of the entire thread along the 650 mm long tube. How do you do that in real life?
- What are you trying to calculate? What result do you want from the analysis? For example, is the stress too high? Will it buckle? Will it get too hot? What???
"Please see the attached image."
- There was no image attached. The model was attached, but that does not explain what you are trying to simulate. It only shows us the component that you are trying to analyze.
