    Simple code in Access

    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...

    New grad engineer - still unemployed!

    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...

    Changing careers - HVAC manufacturing to consulting?

    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...

    How to define path with commands?

    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...

    How to apply multiple materials to different areas?

    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...

    Hiding volumes in postprocessor

    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.

    Modeling cylinders with brick elements - possible?

    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...

    Negative NPSHa!?

    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...

    How to apply distributed loading on a curved line?

    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...

    How to specify size of solid elements?

    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 need help with uncertainty of a curve fit

    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 http://www.eng-tips.com/viewthread.cfm?qid=261269&page=1 But it seems to be that the mean and standard deviation...

    Stress transformation question

    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...

    Uneven meshing density on one area?

    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...

    Determination of Poisson's ratio from axial/transverse strain

    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...

    Pro/E Neutral files

    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";""...

    Multivariable algebrain equations

    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...
