Kan, you are right: it works on another PC... I am going to investigate. Thank you for your input!

Hi all, Has anyone experienced problems plotting graphs with Ansys V12 (APDL)? I am creating a short table (2 col, 4 rows) and want to plot one column as function of the other. The following code works fine with V11, but with V12 only the name of the table and the title of my graph are...

Hello all, I need to make some machining on carbon/epoxy composite parts, so i have to buy some diamond-coated endmills. I found two types of coatings in the catalogs: diamond and diamondlike coatings, with diamondlike being half the price of diamond. Has anyone already tried diamondlike-coated...

@CompositePro Silver Sharpie works great! Thanks a lot...

Thanks for your tip, I'm going to try it. I have already tried white colored Sharpie Paint, but the "ink" seems to impregnate the fibers and almost disappear.

Hello all, Does anyone know any type of paint/primer/whatever that can be sprayed on top of carbon fabric, without altering the resin infusion properties and mechanical properties (fiber/resin adherence, resin strength, and so on...)? I would like to "draw" the shape of the carbon/epoxy samples...

Hello all, Does anyone know a command that could allow me to know the maximum allowed length of a command line in M-files? I have a very long expression to solve and I would like to know if I have to cut it into smaller expressions. Thanks!

Thanks ElectricPete, I used your hint #2 and it works fine!

Hello all, My question relates to Matlab syntax and the way Matlab communicates between M-files and function files. I am trying to solve a system of 2 non-linear equations (with 2 unknowns) using the fsolve command. I wrote a function (function solu = myequations(guess)) that contains my 2...

Hello everyone, I am currently designing a structure made of carbon fiber composite plates (the resin is epoxy) incorporating some Ti-Ni inserts. Ti-Ni is a shape memory alloy. I am wondering if there could be a galvanic corrosion problem with this design (carbon with Ti-Ni). The structure is...

Hi all, This is not my first post on that subject, but I don't find any input. So I will try here to simplify my problem. I want to extract the interlaminar stresses at an interface between 2 layers, for a composite plate under uniaxial extension. For instance, if I take a [45/-45]s laminate...

Hi everyone, Here is a question about interlaminar stresses in Ansys. As you know, obtaining interlaminar stresses between two layers of a composite is quite tricky in FE analysis. But I'm wondering about the right way to get Sxz (shear interlaminar stress) at a particular interface. In my...

Hora, Yes, I can use the Setup, but the reason for which I asked the question is that I would like to write a simple code in "Relations", from which my students could change the system of units by setting a variable to 0 or 1, for example. And then the part (a gear tooth) would be updated...

Hi all, I'm wondering if it is possible to switch from a system of units to another by programming in the "Relations" menu. I know I can write "If" commands and so on, but is there a system variable that specifies the system of units and that I could change in the Relations code? Thanks in...

I just want to give you some precisions about my model. Let's consider a rectangular plate (with Length >> width). The length is -Length/2 < X < 0 and the width is -width/2 < Y < 0. There are two symmetry planes (length and width), so only a quarter of the plate is modelled. The layup is...

Hi to all, I'm trying to calculate interlaminar stresses in a composite plate (Sxz, Syz), and I compare my results with those from other authors. I'm using Solid46 elements with 2 elements through thickness for each layer. the case is very simple: a rectangular plate under uniaxial tension...

I think you're right, cbrn. Thanks for your helpful tips!

Thanks Cbrn and Stringmaker. I will write a Newton-Raphson algorithm. But it would have been interesting to solve with an existing solver! Regards.

Stringmaker, Is there any APDL command for solving equations?

Hi, I need to solve an equation (numerically) in Ansys... May I call a Matlab session from an Ansys input file, and then use the solution from Matlab to continue the process in Ansys? In other words, I must find the value(s) of x for which f(x)=y, with y known. I mention that f(x) is a...
