    Contact between bolt shank and hole

    Dear all, I am trying to model the bolted connection between two pipes with friction contacts involved. I am a new one in contact analyse. I am modeling the contact between two end plates, contacts between head, nut and end plates and contact between the shank of the bolt and hole. First one...

    contour plot as gradient triad display

    Hi, I would like to plot the pressures in postprocessor as gradient triad display in Ansys 13.0 for my 2D model. I set the powergraphics OFF as suggested in ansys help for /CTYPE, but display did not changed...Any suggestions ? Lubo

    node in particular position on line

    Hi, I am going to create a beam model of quite complex building. I would like to first create a solid model (keypoints+lines) which will be meshed with beam elements. But on some lines I need to have a node in special position ( I do not need an advice like "divide this line to have two lines"...

    declaration of functions

    Hi, I am a new one in Matlab, but I have previous experience from Ansys-APDL and Mathcad. I have a question: In the attached there are two m-files with declaration of function. Function Alpha_2(Lambda_1, Lambda_2) works on interval: for Alpha_2(0.4, 0.4) returns correct value and for let us...

    EN 1993-1-8 table 6.7 challenge ...

    Hi, I only hope there is someone to help me with this one... In the attached table I marked two identical formulas ( by the way do you know the stupid game "find ten differencies" ? :-) ). I can only guess that there is somewhere a mistake in incides... Does someone know whether it is...

    link 180 + beam 44

    Hi, I want to use a tapered beam element for main structure and link element for modeling tension-only cables. So I created a model with beam 188 and link 180 which works well, but I realized that with beam 188 takes my non-linear slow-dynamic transient analysis considerably longer compared...

    The file could not be opened for reading...more memory ?

    Hi, I have a table of values in excel which contains over 16000 rows. I would like to read it to Mathcad, but error message "The file could not be opened for reading. Make sure the file exists and is not in use by another application" pops up. Only when I reduce the number of rows in excel I...

    highlighted selected items

    Hi, Generally, if you select some items, only these items are visible, but is there a way how to see the rest of items as well let us say grayed or shaded ?

    This function refers to itself inconsistently

    hi, on the left in attached there is a piece of code working correctly for parameter h=1,2,3 written on the begining. So I would like to automatize this process and changing h automaticly with another for-loop. And this simple extension is placed on the right in attached, but as you can see...

    function composed from another functions - "solve" does not work

    Hi, I have a function composed from another 3 functions and I like to obtain points where f(x) = 0. So in attached I expect 4 values, but solve does not work. Please help. Regards

    fitting curve doed not work

    Hi, I have a set of data in tabular form. I would like to fit a function over this set and then derive this function. I have checked a manual and found I think appropriate commands - bspline and interp, but when plotted in one graph I can see it is not correct... I usually use 1 as array...

    shear studs - negative moment

    Hi, ...just simple question. Let us consider composite (steel and concrete) one span beam. In case of simply supported beam I design number of shear studs from min(Ac*0.85*fc, Aa*fy). Then divided by length of the beam and by number of studs in one transversal row. Then I can this longitudinal...

    The same problem, different approaches - different results - HATE IT !

    Hi, I created a piece of code, which automaticly return maximal internal forces from a file. Then I realized that I can simplify my code with built-in mathcad functions. So I created a new code but then I realize that results are different...I tried to set higher precision, but it did not work.

    rotated supports

    Hi, maybe just simple question, but now i solve simultaneously some another partial problems, and currently i am not able to solve this one. i model a cable by link10 going under a angle according to attached picture. I do not care about upper support, but in lower suppor i want to apply a...

    3D array generated by for-command error

    Hi, I have a set of input data which contains internal forces of number of beams together. I created a code which sorts these data automaticly. I think I wrote it correctly, but it seems mathcad does not agree... The first piece of code identified that there are 4 beams and for each of them...

    calculation via graphic card

    Hi I am just curious. Is there a possibility to run ansys solution via graphic card ? I found some general basic information on google, I tried find on ansys.com and on this page, but with no success. I only know that it is possible with Matlab.

    2D wind flow over cylinder

    Hi I made a simple 2D model of cylinder to verify coefficients of pressure according to Eurocode EN1991-1-4. In this code the coefficients of pressure are plotted for Reynolds number 10000000 what fits to wind velocity 21.71m/s with diameter of cylinder 4m. So I made a 2D model which fits to...

    Guidelines on an analysis

    Hi I need to verify a design of automobile lifting device (attached file 01.tif). I have never done such an analysis before and unfortunately I do not have any experience or someone to ask. So I ask YOU to help me with some guidelines. As you can see there is a runner (diameter of roller...

    xml output format

    Hi, I use Mathcad to generate me a table in format requested for xml. But actually this is only txt file with suffix xml. When I import it I obtain an error message sais me that change of encoding is not allowed. Then I realised that on the start of file is: <?xml version="1.0"...

    num2string command problem

    Hi, I would like to export the result from my calculation in Mathcad to file for use in another software. But I need a special format of exported values. In an attached file I enter a value h0 for calculation, but I need the format of it for export with use of num2string command as shown in...
