Yes, just a diameter change along the length of a cylinder

Hello Vumat and thanks again for the very helpful advice. Yes that is correct, i am tryin to generate a cylinder. However, i want to generate a cylinder with a changing cross-sectional area. Do you have any advice on how i could do this?

Thanks for your invaluabale advice again. You've been really helpful!! I want to try extruding the quarter circle to give a quarter cylinder. However, i'm having difficulty in doing this as i'm unsure on how i would do the node numbering. Do you have any tips on how i could do this?

Hello Vumat and thanks for your help. Do you by any chance have the original input file? (not parameterized). The thing is that i actually want to perform a parametric study on a cylinder rather then on a circle? If i am able to make a circle from your quarter circle example, then is it...

Hello Mr goldthorpe and thanks for your replies. However, my real problem is that i don't no how to generate the elements incrementally for the circle. Do you know how i could go about this? I know how to do this for squares, but i just cant do it for the circle!! Thanks again an advance!

Hello Vumat and thanks again for your reply. So yes, i am first creating a 'user-defined input file', and i am using various examples (such as section "8.3 Investigating the skew sensitivity of shell elements") to help me acheive this. I then want to parameterize this input file using the...

Hi Vumat and thanx for your reply. Your right. I will be doin my parametric study using python scripting. However i am not completely sure of how i would apply the mesh using co-ordinates. If it's not too much trouble, would you be able to explain this, by applying this to my input file...

Hello I need to be able to define the circle in the input file as i want to perform a parametric study. I cannot do this in CAE, as otherwise this comes up as co-ordinate data in the input file, which is far more difficult for me to parameterize. Do you know how to define a circle in the...

Hello ultimately i would like to create a circular face with a mesh that converges in on the circle's centre. Is this possible?

Hello everyone. Does anyone know how to define a circle (a face) in the input file. I have been able to define the basic shape of a semi-circle, but i am having difficulty with generating the nodes and elements. Any help would be greatly appreciated Thank You!

Hi everyone. I am using abaqus 6.8 and have been able to import Abaqus's user defined input files (For example, the skew sensitivity of shell poblem). However, lately i have been unable to do this, and i am really unsure of why. Now when i try to open the files, I get an error message saying...

I want to perform a parametric study, where the geometry of an object is varied. However, the only catch is that I need to be able to do this by parametrizing the input file. I have given an example below to more clearly explain, what I am trying to say. Let’s just say i have a cube, and i...

Hi and thanks for your reply. My cylinder is an axisymmetric deformable model. I have fixed it with an encastre, and a applied a moment at the top edge (I have included an image of this in the attachment). I have also tried to apply the moment from the top of the cylinder center (on the...

Hello everyone. I need to apply a torsional load to the top face of a cylinder. I try doing this but my analysis doesnt run. I am using Abaqus 6.7 EF-1. Can anyone help?

Hey thanks for ur help people. I have got this problem sorted now. Thanx again!!

Hello mrgoldthorpe, and thanks for your help. The thing is i cannot actually import the model. So i cannot do a datacheck, as there is no model defined. Or am i doing somthing wrong. Sorry if you mean something else. I am still a fairly new user to Abaqus.

Hello. I am trying to open parametrized input files. I do this by importing them as models. However when i do this, a warning message always comes up: WARNING: The input file contains one or more data items which have been parameterized. Parameterized input files can not yet be imported into...
