I want to model two volumes as shown in the graph(see file). One is a solid cylinder and the other is a solid block. In reality, the cylinder is inside the solid block, and the solid block had been rigged a hole first.
The aim is to model the pullout of the cylinder.
However, in ANSYS APDL there are two options to build the geometry
One method is just to create two solid volumes at the same time. Ignore the hole.
Another option is to create the block first, then dig a hole and then recreate the inside cylinder.
Please what is the difference between these two volume creating methods?
Dear Shi Sulun,
I see the most optimal way of doing you need in the next:
block, -1, 1, -1, 1, 0, 1
cyl5, -0.2, -0.2, 0.2, 0.2, 1
vsbv,1,2,sepo,delete,keep
What do you mean when write about the 2nd way? Something like that:
block, -1, 1, -1, 1, 0, 1
cyl5, -0.2, -0.2, 0.2, 0.2, 1
vsbv,1,2
cyl5, -0.2, -0.2, 0.2, 0.2, 1
but it just means the redundant work.
But, maybe, you mean something else, threfore, give more explanations.
Hi Alexey Kuzin
Thanks for the answer. Let me describe it more clearly.
The first method's sequence is just to create two solid volumes, one cylinder, and one solid block. Hence the hole inside the block is not been created.
The second one, in terms of the graphical interface, is to create two solid volumes, one cylinder, and one solid block. Then use the Boolean operation to subtract the solid cylinder volume and finally recreate the inside solid cylinder.
Yes, they are similar. But may affect the modeling result, but I don't know. Hence, are there any differences ?
Shi Sulun ,
Does your first method also mean that the hole in the block is made anyway? If so, I think, there is no difference how do you make bored block and cylinder. At least I do not see the difference from point of view of analysis.
But if you do not make the hole and the bodies intersect one each other this is invalid geometry!
