Hello,
First of all, I am going to admit that I have no idea how to program in VBA. In fact, I don’t even think I entirely understand what Access does. My programming experience has been mostly MATLAB (nothing more than simple loops and conditionals and whatnot, plus the Control System Toolbox...
I live in the Alberta province of Canada, and I graduated just recently from the local university this spring with a BSc in mechanical engineering. I have around a year of experience as a research assistant at the university, but nothing else beside that. I missed the September hiring season...
I'm at a bit of a crossroads at the moment. Having just finished my mechanical engineering degree this spring, I've been offered a position with an HVAC equipment manufacturing company (for pretty decent pay, no less). I like the company environment, and the work they do does seem very...
Hi everyone,
I'm trying to define a path along a curved line in a 2D model in ANSYS. This would normally be easy with the GUI, except I have hundreds of nodes on the curved line that are randomly numbered.
I checked the commands log that's produced by GUI operations, and the program used a...
Hi all,
I'm trying to construct a beam made of 2 sections joined together, one part is steel while the other part is epoxy. I'm using axisymmetric PLANE83 to model the beams in 2D.
Initially, I defined each material property set first, using MP,1,... and MP,2,.... Then, I used MAT to move the...
Hi all,
I used a roughly meshed volume in ANSYS for the purpose of load application, but I would like to hide it for postprocessing. Is this possible? Any help would be appreciated.
Hi,
I'm trying to mesh a hollow cylinder in ANSYS using mapped meshing, but ANSYS doesn't seem to be able to do this. According to the documentation, it appears that this is because ANSYS requires 3 sets of 2 opposite faces on the model, like a cube.
So I guess my question is, how exactly may...
Hi guys,
I'm designing a pumping system to pump out water from a well, and the water level is around 50 ft below grade. Since 50 ft. is more than the atmospheric pressure in feet of water (around 32 ft of water), I get negative NPSHa, which means the pumps suffer from cavitation. How would I go...
I'm modeling a connecting rod in an engine with a line and 2 circles, which are for connecting to the piston pin and the crankshaft. I want to model the piston and crankshaft loads as distributed loads, but using PRES applies a load that's perpendicular to the line everywhere.
So my question...
First of all, I'd like to admit that I've only really used ANSYS (seriously anyway) for a few weeks in a FEA course, and I have absolutely no idea what I'm doing.
Basically, I want to mesh a very basic solid model that's in the shape of a rectangular block with a couple of holes on it. The...
I'd like to know how I can find the uncertainty in "m" and "b", the two constants you get when you make a linear curve fit "y=mx+b".
I know there's a similar topic just below here

But it seems to be that the mean and standard deviation...
I have normal stresses in x, y, and z along with shear stress in x-y. I am rotating the coordinates about the z axis, so the normal stress in the z direction should be the same in the new coordinate system as in the old.
My question is, since the stress in z does not change, and since all the...
I'm modeling a cylindrical specimen made of two sections of different materials, attached end-to-end, and loaded in tension. There should be a stress concentration at the outer edge of the bi-material interface. I'm modeling the whole situation as an axisymmetric problem in ANSYS.
The problem...
I just did a tensile test on a piece of cold-rolled 1018 steel specimen to determine the properties of the batch of steel. With all the data in Excel, I have a column for axial strain, and a column for transverse strain.
To find the Poisson's ratio of the material, would it be better to find...
Can anyone help me figure out what "Pro/E neutral" files are for? I just downloaded some 3D part models from FAG Bearing's website, and they came as zip files with a bunch of .neu.1 files and a single text file, which reads
"Symbol";"Value";"Unit";
"DESIGN";"Angular contact ball bearings";""...
I'm trying to do Castigliano's theorem in Mathcad. Integrating in Mathcad is pretty easy, but is there a way to implicitly define functions?
For example, I would like to be able to enter
-M + F*0.026m + Q*0.036m = 0
(which is a force balance on a free body diagram)
and let Mathcad turn the...
